FEATURES AND BENEFITS CONTROLS Intelligent Unit Controller
The Integrated Modular Control (IMC) is a solid−state microprocessor−based control board that provides flexible control of all unit functions. All control voltage is provided via a 24V (secondary) transformer with built−in circuit breaker protection. Built-in functions include: Blower On/Off Delay − Adjustable time delay between blower on and off. Blower Air Delivery Options − Three air delivery options; single zone CAV, bypass zoning with bypass dampers, and modulating VAV with VFD. optional GP1 board required for VAV or bypass zoning. Built-in Control Parameter Defaults − No programming required for standard CAV models. Compressor Time−Off Delay − Adjustable time delay between compressor shutoff and start up. DDC Compatible − Various third party DDC controllers can be factory or field installed. Refer to the Unit Controllers section for details. Dirty Filter Switch Input − When a Dirty Filter Switch is installed, the IMC will signal when the indoor blower static pressure increases, indicating a dirty filter condition. Switch is optional and can be factory or field installed. Discharge Air Control − The IMC will cycle up to 4 stages of heating or cooling to maintain the discharge air setpoints for heating or cooling. The factory installed discharge air sensor must be relocated to the supply duct for proper measurements. Display/Sensor Readout − Displays control parameters, diagnostic codes, and sensor readings. The IMC unit controller displays temperature readings from return air, supply air, and outdoor air sensors that are furnished as standard on all L Series units. IMC will also display readings from optional sensors such as zone sensors, CO2 sensors or relative humidity sensors. Economizer Control Choice − the economizer is controlled by an add−on board to the IMC. The economizer control board has four choices (DIP switch selectable) for controlling the economizer. 1 − Sensible Control − Uses the outdoor air and return air sensors that are furnished with the unit. The IMC compares the two temperatures and enables the economizer when the outdoor air is cooler than return air.
2 − Differential Sensible Control − Uses the outdoor air and return air sensors that are furnished with the unit. The IMC compares the outdoor air and return air and, using setpoints, enables the economizer when the outdoor air is cooler than return air. 3 − Global Enthalpy Control − the IMC communicates with a DDC system that uses one global sensor (enthalpy or sensible), to determine whether outside air is suitable for free cooling on all units connected to the control system. Sensor must be field provided. 4 − Outdoor Enthalpy Control − Senses outdoor air enthalpy and enables economizer if the enthalpy is less than the setpoint of the board. Can be ordered factory or field installed. 5 − Differential Enthalpy Control − Two solid-state enthalpy sensors allow the control board to select between outdoor air or return air, whichever has lower enthalpy. Can be ordered factory or field installed. Fresh Air Tempering − The IMC energizes the first stage heat as needed to maintain a minimum supply air temperature for comfort, regardless of the thermostat demand. For factory option, sensor ships with unit but must be field installed in the supply air duct. Extensive Unit Diagnostics − The IMC monitors all sensors and functions related to unit operation to provide critical information. The IMC will display detailed diagnostic information with over 80 diagnostic codes to pinpoint any problems and reduce troubleshooting time. All diagnostic codes are listed inside control access panel for easy reference. Exhaust Fan Control Modes − Fans controlled by fresh air damper position (non−VFD power exhaust) or or solid−state building static pressure sensor (VFD power exhaust). Permanent Diagnostic Code Storage − Maintains diagnostic codes through a power failure. Field Changeable Control Parameters − Over 200 different control parameters allow customization of the unit operation by changing delays, cooling stages, deadbands, and setpoints. Indoor Air Quality Input − The IMC is Demand Control Ventilation ready from the factory (optional field installed CO2 sensor required). Two modes of operation are available: setpoint and proportional. 1 − Setpoint − Opens the economizer dampers to full position when CO2 setpoint level is reached. 2 − Proportional − Opens the dampers at the first set point and gradually increases it as the CO2 level increases until the second setpoint is reached. Low Ambient Controls − Allows unit cooling operation down to 0°F.
Gas Valve Time Delay Between First and Second Stage − Allows gradual increase of input rate. Minimum Compressor Run Time − Ensures proper oil return to the compressor. Network Capable − The IMC can be daisy chained to other L Series units or L Connection ® Network controllers using twisted pair wire. Night Setback Mode − Adjusts setpoints, closes outdoor air dampers and operates the blower on demand, may be customized for special requirements. Return Air Temperature Limit Control − Allows the user to override the demands based upon the return air temperature during either heating or cooling operation. Helps protect against abnormal operating conditions in the event of a room sensor or thermostat failure. Safety Switch Input − Normally−closed digital input allows the IMC to respond to a external safety switch trip (phase protector, low voltage, etc.) shutting down unit operation. Service Relay Output − Digital output can indicate a critical error has occurred to an external control device. Can also be configured to energize based on relative humidity, indoor air quality, outdoor air temperature or unit operation. Smoke Alarm Mode − Control board has four choices for responding to a smoke alarm. 1 − Unit Off − unit will turn off. 2 − Positive Pressure − blower is energized, exhaust fan is de−energized, and the outdoor air dampers are opened. 3 − Negative Pressure − blower is energized, exhaust fan is energized, and the outdoor air dampers are closed. 4 − Purge − blower is energized, exhaust fan is energized, and the outdoor air dampers are opened. Staging − 2 heat/2 cool. Capable of up to 4 heat/4 cool with zone sensor or with optional FS1 board and 4 heat/4 cool thermostat or third party DDC control system. Strike Three" Protection − Ends cooling or heating operation when any of the following occurs three times (adjustable) within a thermostat cycle: low pressure trip, high pressure trip, heat limit trip, or freeze−stat trip. Gas Reheat − Control parameter option that allows simultaneous heating and cooling operation on CAV gas units for controlling humidity for process air applications such as supermarkets.

Dehumidification Demand Only The IMC is factory set at 60% relative humidity setpoint and can be adjusted at the IMC or with optional Unit Controller Software. For Network Control Panel (NCP) applications, the humidity setpoint can be adjusted at the NCP. The unit will operate in the dehumidification mode
until the relative humidity of the conditioned space is 3% below the setpoint. Reheat operation will initiate on a dehumidification demand and does not require a cooling demand. The reheat coil is sized to offset most of the first stage sensible cooling effect during reheat only operation. This reduction in sensible cooling capacity extends compressor run time to control humidity when cooling loads are light. Solenoid valves divert hot gas from compressor 1 and compressor 2 to the reheat coil. The cooled and dehumidified air from the evaporator is then reheated as it passes through the reheat coil. The de−superheated and partially condensed refrigerant continues to the outdoor condenser coil where condensing is completed. The unit will continue to operate in this mode until the dehumidification demand is satisfied. A heating demand will terminate reheat operation. Dehumidification and Cooling Demand for 156H/180H three compressor models (Thermostat Application) If both a dehumidification and a first stage cooling demand occur, the system will operate compressor 1 and compressor 2 in reheat and compressor 3 will operate in cooling. A demand for second stage cooling will terminate reheat operation until second stage cooling demand is satisfied. Dehumidification and Cooling Demand for 210H/240H/300S four compressor models (Thermostat Application)

If both a dehumidification and a first stage cooling demand occur, the system will operate compressor 1 and compressor 2 in reheat and compressor 3 and compressor 4 will operate in cooling. A demand for second stage cooling will terminate reheat operation until second stage cooling demand is satisfied. Dehumidification and Cooling Demand for 156H/180H three compressor models (Room Sensor Application) If both a dehumidification and a first stage cooling demand occur, the system will operate compressor 1 and compressor 2 in reheat and compressor 3 will operate in cooling. A demand for second stage cooling will terminate reheat and compressor 3 operation and operate compressor 1 and compressor 2 in cooling until second stage cooling demand is satisfied. A demand for third stage cooling will operate compressor 1, compressor 2 and compressor 3 in cooling. Dehumidification and Cooling Demand for 210H/240H/300S four compressor models (Room Sensor Application) If both a dehumidification demand and a first stage cooling demand occur, the system will operate compressor 1 and compressor 2 in reheat and compressor 3 will operate in cooling. If a demand for second stage cooling is initiated, compressor 1 and compressor 2 will operate in reheat and compressor 3 and compressor 4 will operate in cooling. A demand for third stage cooling will terminate reheat and compressor 4 operation and operate compressor 1, compressor 2 and compressor 3 in cooling until third stage cooling demand is satisfied. A demand for fourth stage cooling will operate compressor 1, compressor 2, compressor 3 and compressor 4 in cooling.
