Leave this bulletin on the job site for future reference! The BMPlus Zone Control System allows you to easily upgrade an inefficient single zone HVAC system, into a Multi-zone, Energy savings, Comfort producing, HVAC system. The Superior Design, Intuitive Firmware, Simple Setup Options, Easy to Understand wiring and Backwards Compatibility, makes the BMPlus Zoning system the Contractors dream. Combined with EWC Motorized Dampers and any off-the-shelf Thermostats, EWC Controls sets another high standard in the residential & light commercial Forced Air Zoning Industry.
Zone Capacity
The main module controls three zones using motorized dampers and may be expanded to 5 or 7 zones, using 1 or 2 Model XM2 Expansion Modules.
Compatible Controls 2 & 3 stage conventional or dual fuel heat pumps, without the need for dual HVAC fuel kits. Also single or two-stage gas, oil, Systems & hydronic heating systems, with single or two stage air conditioning. Constant or variable speed fan systems.
Compatible Compatible with any off the shelf Thermostats H e a t P u m p T h e r m o s t a t (2heat/1cool). You may also use any regular Heat/Cool thermostat (1heat/1cool). You may still use regular Heat/Cool thermostats to control a Heat Pump system.

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 * Staging Timer = OFF or 7-42 min. -Adj. * Supply Air Limit Timer = 3minutes-fixed * Purge Delay Timer = 90 seconds-fixed
*Startup Delay Timer
The panel will not activate any cooling or heating operation until the startup delay has expired. This occurs after any initial power up or power failure. Press the Reset button for 1 second to override.
*Short Cycle Timer
When all zone demands are satisfied, the panel will not resume the same mode of operation for a minimum of 3 minutes.
*Changeover Timer
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.
*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.
Staging Timer / OAS
The STAGING 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 Outside Air Changeover Setting.

42 OFF STAGING 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
The BMPlus 3000 can inhibit heat staging 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 30 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 delay 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.

HP < SYSTEM > OTHER FS DF < HP > CONV FS < TSTATS > HP FS HC FS O < RV > B OAS < STAGING > TIMER FS FS OFF < 50%RULE > ON FS OFF < SAS > ON FS GAS < FAN > HYDRONIC
HP < SYSTEM > OTHER Choose the type of HVAC system you want to control. Select HP, if your system is any type of Heat Pump. Select OTHER, if your system is a standard Gas or Oil furnace. Other setting also applies to straight electric furnaces or hydronic (hot water coil) heating systems.
DF < HP > CONV Choose the type of Heat Pump you want to control. Select DF (Restricted Mode) if you wish to lock out the compressor during auxiliary heat operation, typically set for Dual Fuel operation. Select CONV (Unrestricted Mode) if you wish to have the compressor run during auxiliary heat operations, typically set for Electric Back-up.
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 Heat/Cool Thermostats on a Heat Pump application. IMPORTANT NOTE: The BMPlus 3000 Zone Control System allows Heat Pump thermostats to be connected to all zones. Using heat pump thermostats means that the zone panel will obey thermostatic demands. 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. True thermostatic staging is not available when using 2 Stage compressor heatpumps, it is advisable to use Heat/Cool thermostats and allow the BMPlus to stage via the on-board timer. If true thermostatic staging is required, then it is recommended to upgrade to the Model UZC series of Control Panels.
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 < STAGING > TIMER Select OAS, if you want to delay auxiliary heat based on the outside air temperature sensor. Select TIMER, if you want to delay staging heat & cool based on the adjustable on-board timer. NOTE: ‘Y2’ defaults to a 30 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 Y2 and/or auxiliary heat based on the total number of zones calling. Select ON, if you do want to inhibit Y2 and/or auxiliary heat based on the total number of zones calling. More than half the total zones must be calling for the same mode of operation (heat or cool), or the BMPlus3000 will not stage up. This feature is a great way to save energy. The 50% rule will always dominate the staging timer and 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

Figure 10 – 3 Heat / 2 Cool Heatpump System **Note that a Conventional & Dual fuel heat pump wire up more or less the same. The difference is how auxiliary heat operates. In a Conventional system, the indoor fan & the compressor continues to run when auxiliary energizes. In a Dual Fuel system, the indoor fan & the compressor shuts down when auxiliary 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 auxiliary heat by TIMER or by OUTSIDE AIR TEMPERATURE. (Optional Sensor required). Or you may choose to install Heat Pump Thermostats on all zones. When the thermostat auxiliary 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.

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 STAGING TIME DELAY SETTINGS

Figure 17
On all these dampers and most older style dampers, including competitor’s dampers, always wire up number to number or designation to designation.
Do not overload your transformer!

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.

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 9
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 HVAC system not responding and BMPLUS 3000 LED’s are off. Dampers not responding and THE BMPLUS 3000 LED’s are off.
ISOLATING 24vac SHORTS F1 circuit breaker protects the BMPlus 3000 and reacts to a short in the damper motor or thermostat component and field wiring.
SYMPTOMS: Module(s) appear to be dead! 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. 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.
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.
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.
