Thermal Circuit Breaker
The BMPlus module has a Thermal circuit breaker that protects the module(s) from shorts in the damper and thermostat field wiring. It will not protect against shorts in the HVAC system wiring.
CAUTION: When the circuit breaker is tripped it will get quite hot. To reset the breaker: Shut off power to the panel. Find and repair the short. Restore the 24VAC power. Any zone can activate the indoor fan and only the dampers in zones calling for continuous fan operation will open. Continuous fan operation will only occur when there are no active or pending, heat or cool demands. A dip switch is provided to enable automatic fan operation in heat mode. Useful for straight electric heat or hydronic heat applications. Fan operation is seamless and occurs without interruption from Cool to Heat mode. 1 FAX 732-446-5362 E-Mail-

BMPlus 3000 FIRMWARE/HARDWARE FEATURES The panel has seven built-in Delay Timers that insure safe & reliable operation.
*Built-In Timer Settings
* Start-up Delay Timer = 3 minutes-fixed * Short Cycle Timer = 3 minutes-fixed * Change Over Timer = 4 minutes-fixed * Opposing Call Timer = 20minutes-fixed * 2nd Stage Timer = OFF, 7-42 min. -Adj. * Supply Air Limit Timer = 3minutes-fixed * Purge Delay Timer = 90 seconds-fixed
*Startup Delay Timer
The panel will not activate a cooling or heating operation until the startup delay has expired. This occurs after any initial power up, after any power failure or after pressing the Reset button for 7 seconds.
*Short Cycle Timer
When the system is satisfied, the panel will not resume the same mode for a minimum of 3 minutes.
*Changeover Timer
*Opposing Call Delay Timer
A 20 minute delay must expire, or the active zone(s) must satisfy, before the panel will honor a thermostat demand to changeover to the opposite mode of system operation.
*2nd Stage Timer / OAS
The 2nd STAGE TIMER sets the amount of continuous call time in 1st stage, before second stage heat or cool is energized. NOTE: The potentiometer also serves as the 2nd stage Heat Outside Air Changeover Setting.

28 35 42
OFF 2nd STAGE Timer / OAS
OFF, 7 to 42 minutes or 7 to 42 degrees F. Any setting below 7 is off! DO NOT set to off if using OAS
*Supply Air Limit Delay Timer
*Purge Delay Timer 2
A built-in timer prevents the system from rapidly switching between heating and cooling modes. At the end of a call, a 4 minute timer is started and the panel will not switch to the opposing mode until the timer has expired.
The BMPlus 3000 can inhibit 2nd stage heat based on a Timer or Outside Air Temperature. NOTE: An Optional OAS Sensor is required to use the OAS feature. NOTE: 2nd stage cool delay defaults to 15 minutes, if OAS is chosen to inhibit 2nd stage Heat. The time delay of 3 minutes must expire before the BMPlus 3000 will re-energize heat or cool mode. This occurs when the processor detects the supply air temperature is higher or lower than the High or Low temperature limit settings. The last Damper(s) will be held Open for 90 seconds at the end of every call allowing a system purge into the last zone that was calling.

Example: Hi Temp. Limit =130°F plus 2nd stg. DT= 40°F New Limit = 170°F.
Reset BUTTON
RESET Always reset the CPU anytime you make dip-switch changes to the BMP3000 panel! DO NOT use a sharp object to press the button! Your finger tip will work fine.
The Adjustable Cooling Limit potentiometer sets the supply air temperature at which the cooling is cycled off and the fan continues to run, allowing the coil to warm up. The Adjustable Heating Limit potentiometer sets the 1st stage heat supply air temperature, at which the heating is cycled off and the fan continues to run, allowing the heat exchanger or coil to cool down. The Adjustable 2nd stage heat differential potentiometer sets the 2nd stage heat supply air temperature, at which the heating is cycled off and the fan continues to run, allowing the heat exchanger or coil to cool down. NOTE: Allows the supply air sensor to be installed in the supply air plenum, regardless of the coil/heat exchanger configuration. Allows the installer to fine tune virtually any 2 stage heating system! The separate reset buttons on the old BMP3000 have been replaced by a single button with dual functions. Momentarily pressing the RESET button clears the built-in timers controlling the Startup delay timer, Short cycle timer, W2 timer, Supply air sensor timer and the Changeover timer. This enables you to test the installation faster. Caution should be observed when using this button.
Pressing the RESET button for 7 seconds will reset the CPU for the entire zone system.
Emergency Heat Switch
An On-Board Switch is provided that allows the Customer to set the system to the Emergency heat mode.
EM
This switch is shown in the NORMAL position.
NORM
This switch would be used for Heat Pump applications where the Customer chooses to use Regular Heat/Cool thermostats instead of Heat Pump thermostats.

HP < SYSTEM > GAS Choose the type of HVAC system you want to control. Select HP, if your system is any type of heat pump. Select GAS, if your system is a standard Gas or Oil furnace. Also applies to straight electric furnaces or hydronic (hot water coil) heating systems. NOTE: If HP is selected at dip switch 1, Y2 is not available. Y2 is only available in GAS mode.
DF < HP > CONV Choose the type of Heat Pump you want to control. Select DF, if your system is a dual fuel heat pump with gas or oil furnace backup heat. Select CONV, if your system is a conventional heat pump with electric resistance backup heat. Also applies to Ground source/Geothermal heat pumps.
HC < TSTATS > HP Select HC, if you want to use regular Heat/Cool thermostats on your job. Select HP, if you want to use Heat Pump thermostats on your job. Remember that you can use standard HC T-stats on a Heat Pump application. IMPORTANT NOTE: The BMPlus 3000 Zone Control System allows Heat Pump thermostats to be connected to all zones. When doing so, make sure you turn the 2nd stage timer to the “OFF” position. Using heat pump thermostats means that the zone panel will obey thermostatic demands and ignore Timer operations. This comfort over-ride feature provides a level of versatility to your zoning system and gives the homeowner comfort control over the system, instead of waiting for the adjustable timer to energize 2nd stage heat.
O < RV > B Select the correct Reversing Valve signal for your particular Heat Pump. Choose “O” for any heat pump that energizes the RV in the cooling mode. Choose “B” for any heat pump that energizes the RV in heating mode.
OAS < 2nd STAGE > TIMER Select OAS, if you want to delay 2nd stage heat based on the outside air temperature sensor. Select TIMER, if you want to delay 2nd stage heat & cool based on the adjustable on-board timer. NOTE: 2nd stage cool defaults to a 15 minute delay, when OAS is chosen. NOTE: An optional Outside Air Sensor (OAS) is required to use the OAS feature.
OFF < 50%RULE > ON Select OFF, if you do not want to inhibit 2nd stage heat/cool based on the total number of zones calling. Select ON, if you want to inhibit 2nd stage heat/cool based on the total number of zones calling. More than half the total zones must be calling for the same mode, or 2nd stage will not activate. If DF or OAS has been selected, the 50% rule will apply to cooling operations only. 2nd stage heat will not be affected. The 50% rule will always dominate the 2nd stage timer or thermostat demands unless Emergency mode is active.
OFF < SAS > ON
Select OFF, if you do not want to use the supply air sensor included with the BMPlus Zone Control system. Select ON, if you intend to use the included supply air sensor. Refer to the data sheet included with the supply air sensor for details.
GAS < FAN > HYDRONIC Select GAS, if your HVAC system is a gas or oil forced air furnace. Select HYDRONIC, if your HVAC system has a hot water coil, or straight electric heat with no indoor blower support. Useful when you need the indoor blower to run automatically in heat mode, just like it does in cool mode. NOTE: When you select HP on dip switch #1, the indoor fan mode is automatically set for you. There is no need to move this switch when setting up for Heat Pump operations. EWC Controls Inc. 385 Highway 33 Englishtown, NJ 07726 800-446-3110 FAX 732-446-5362

The BMPlus will accept heat pump style thermostats in all zones. This allows you to energize 2nd stage heat thermostatically instead of through the W2 timer. Also, Emergency heat can be activated from any zone.
NOTE: The New BMPlus 3000 allows the user to install Heat Pump thermostats on all zones. This allows the user to turn off the W2 Timer and energize the auxiliary heat via thermostatic demand! You may still use regular Heat/Cool type thermostats with a Heat Pump system and use the W2 Timer to energize the auxiliary heat. Doing so may save more energy. This new design simplifies the thermostat selection process and allows the installer to easily adapt the BMPlus 3000 to any residential applications.

Dual Fuel Heat Pump with “O” Type Reversing Valve **
Figure 10 Single stage heat pump and 1or 2 stage furnace. **Note that a Conventional & Dual fuel heat pump wire up more or less the same. The difference is how 2nd stage heat operates. In a Conventional system, the indoor fan & the compressor continues to run when 2nd stage energizes. In a Dual Fuel system, the indoor fan & the compressor shuts down when 2nd stage energizes. The BMPlus 3000 will perform these functions automatically. All you have to do is set the dip switches to the correct settings. Select CONV or DF at dip switch #2. Install regular Heat/Cool thermostats and choose to activate 2nd stage heat by TIMER or by OUTSIDE AIR TEMPERATURE. (Optional Sensor required). Or you may choose to install Heat Pump Thermostats on all zones and turn the Onboard Timer OFF. When the thermostat 2nd stage heat demand is satisfied, the BMPlus 3000 will stage down, unless DF or OAS has been selected and the outdoor temperature is lower than the OAS changeover setting. In that case the system will continue in FUEL mode, until all current heating demands are satisfied.

HVAC system with OEM Voltage Control Circuitry Some HVAC manufacturers are designing HVAC Systems with 5 - 18 vdc control circuits. Standard 24 vac thermostats will not work on these systems. These systems can only be controlled with their own thermostat. But the SYSTEM connections on a BMPlus 3000 are all dry contacts! Virtually any HVAC low voltage control circuit can be connected and controlled. All you have to do is ask the manufacturer which numbered terminal corresponds to the standard terminals.

ENHANCED FEATURES AND FUNCTIONS MODULE TO MODULE FACTORY POWER WIRING
SHORTED ZONE FEATURE FIRMWARE
The BMPlus 3000 includes Factory Power Wiring on all expanded systems. The 24 vac power to the expansion modules is fed through the bus cable. This simplifies your wiring and minimizes the chances of reversing polarity.
The BMPlus 3000 Zone Control System includes the Shorted Zone Feature. This feature allows the BMPlus to ignore demands from a zone thermostat that is putting out simultaneous demands for heat & cool. A condition most likely due to a short in the field wiring, incorrect wiring, or a defective thermostat. The BMPlus will honor any legitimate demands from any other zone(s), except the shorted zone. When the problem is identified and repaired, the BMPlus 3000 will automatically recognize that zone.
DUAL FUEL COMPATIBLE
The BMPlus 3000 is compatible with Dual Fuel Heat Pumps. Dual Fuel kits are not required. Select staging based on Adjustable Time Delay or an Optional Outside Air temperature Sensor. The intelligent firmware does the rest. * OFF, 7 TO 42 MINUTE 2ND STAGE TIME DELAY SETTINGS

DAMPER WIRING CONTINUED If you need to connect numerous dampers to a single zone, or you are using dampers of unknown current draw such as Spring Types, Isolation relays and separate power supplies may be required. Parallel as many dampers as you want as long the total current load of the motor actuators does not exceed the VA rating of the transformer. Other factors should also be considered, such as the full load amp rating of the isolating relay contacts, voltage drops from long wire runs and feeder conductor sizing to junction points. NOTE: Some older style dampers and competitor’s dampers cannot be paralleled and must be isolated or wired in tandem. Contact EWC Controls Technical Support for assistance. Variations on this diagram and other damper solutions are available.

Non-inherently current limiting transformers must have field provided over-current protection on the secondary 24 vac output. The table values provided pertain to genuine ULTRAZONE Dampers and Competitors typical 24vac Spring loaded dampers. Included in these VA load ratings are the correct number of thermostats, the BMPlus Zone System, and a 5% field factor. Spring loaded dampers draw higher currents & require more power.

SOLUTIONS
LED’S are responding properly but HVAC system is malfunctioning.
Check HVAC system wiring for proper connections. Check HVAC system wiring for shorts/miswiring. Check HVAC System. Refer to Technical Bulletin for correct Setup/Wiring/Dip Switch settings.
LED’s are not responding properly and HVAC system is malfunctioning.
Check HVAC system wiring for shorts/miswiring. Check HVAC system wiring for proper connections. Check HVAC thermostat for proper connections. Refer to Technical Bulletin for correct Setup/Wiring/Dip Switch settings.
LED’s illuminate and HVAC system functions normally but dampers do not respond.
Check damper motor wiring for proper connections. Check damper motor 24vac transformer voltage/fuse/BMPlus circuit breaker. Check damper motor wiring for shorts/miswiring. Refer to Technical Bulletin for correct Setup/Wiring. REFER TO THE DAMPER MOTOR TESTING PAGE 8
LED’s do not illuminate and HVAC system does not respond.
Check HVAC & BMPlus system transformer supply voltage. Check HVAC & BMPlus system 24vac transformer voltage, fuse & the BMPlusB circuit breaker. Check HVAC & BMPlus system wiring for shorts/miswiring.
CHECK YOUR WIRING DETECTING 24vac SHORTS
SYMPTOMS: Module(s) appear to be dead!
HVAC system not responding and BMPLUS 3000 LED’s are off. Dampers not responding and THE BMPLUS 3000 LED’s are off.
If 24vac short has occurred, 24vac will be present at the BMPlus 3000 Module Input terminals R & C; but 24vac will not be present at the Thermostat R&C.
ISOLATING 24vac SHORTS
Disconnect the wire(s) from the ‘R’ terminals on the BMPlus 3000 thermostat terminal blocks , and the “M2/M4/M6’’ terminals on the BMPlus 3000 damper motor terminal blocks. Restore power. If the short is no longer present, Ohm out the thermostat and damper field wiring for shorts/misconnections. Replace or repair wires as necessary. Restore power. Module(s) will resume operation.
F1 circuit breaker protects the BMPlus 3000 and reacts to a short in the damper motor or thermostat component and field wiring.
SOLUTIONS: Remove 24vac power from BMPlus 3000 and allow circuit breaker to cool! Find and repair short(s) in damper and/or thermostat field wiring. Restore 24 vac power.
TESTING THERMOSTATS Check to make sure that the thermostat Rc and Rh terminals are connected together, unless your application requires separation of these circuits. Use the (C) Common terminal provided at each thermostat terminal block to wire up full 24 vac hard-wired thermostats. You should reference the (C) Common terminal when troubleshooting incoming thermostat demand signals, even if no wire is connected there. Make sure that you wire and configure your thermostats for the correct application. Most thermostats built today can be field configured to operate as regular Heat/ Cool type or as Heat Pump type. Remember that you can use regular Heat/Cool thermostats on the BMPlus 3000 for Heat Pump applications.
