Random Start Delay

This delay will be used after every power failure, as well as the first time the compressor is started after the control exits the unoccupied mode or the emergency shutdown mode. The delay should not be less than 1 second and not longer than 120 seconds. If the control is in test mode the random start delay will be shortened to 5 seconds.

Compressor Fixed On Delay Time

The Compressor Fixed On Delay Time will ensure that the compressor output (B02) is not enabled for (90) seconds after the control receives a call to start the compressor.

This delay is adjustable from 30 – 300 seconds over a BAS or a MUI. If the control is in test mode the Compressor Fixed On Delay Timer will be shortened to 5 seconds.

in medium speed and will operate in high speed when the compressor is operating at full capacity.

Thermostat Control Mode

In thermostat mode the compressor will be cycled based on Y1 and Y2 calls from a room thermostat. When the control receives a Y1 command (BI-7) from the thermostat the low capacity compressor output (BO2) will be enabled and the ECM2 blower will oper- ate in medium speed. When the control receives a Y2 command (BI-8) from the thermostat the full capac- ity compressor output will be enabled and the ECM2 blower will operate in high speed. During the heating cycle the reversing valve will be commanded into the off position.

Compressor Minimum On Delay

The compressor minimum on delay will ensure that the compressor output is enabled for a minimum of (2) minute each time the compressor output is enabled. This will ap- ply in every instance except in the event the high pressure switch is tripped or emergency shutdown then the com- pressor output will be disable immediately.

Compressor Short Cycle Delay Time

The compressor short cycle time delay will ensure that the compressor output will not be enabled for a minimum of

(5)minutes after it is disabled. This allows for the system refrigerant pressures to equalize after the compressor is disabled.

Heating Cycle

On a call for heating, the blower enable output and acces- sory output 2 will turn on immediately after the random start delay timer has been satisfied. If the compressor short cycle time delay has been satisfied, the compressor will turn on after the blower enable and accessory output 2 are on and the fixed compressor start delay timers have been satisfied.

Auxiliary heat output can be controlled over the BAS.

Set Point Control Mode

In set point control mode the reversing valve output will be disabled. As the temperature drops below the heating set point and begins to operate in the heating proportional band, the low capacity compressor out- put (BO-2) will be enabled. A PI loop in the program- ming of the control will determine when the full capac- ity compressor output (BO-4) is to be enabled. The compressor must be operating in low capacity for a minimum of 30 seconds before the full capacity com- pressor output can be enabled. During low capacity compressor operation the ECM2 blower will operate

Cooling Cycle

On a call for cooling, the blower enable output and acces- sory output 2 will turn on immediately after the random start delay timer has been satisfied. If the compressor short cycle time delay has been satisfied, the compressor will turn on after the blower enable and accessory output 2 are on and the fixed compressor start delay timers have been satisfied.

Set Point Control Mode

In set point control mode the reversing valve output will be enabled. As the temperature falls below the cooling set point and begins to operate in the cooling proportional band, the low capacity compressor out- put (BO-2) will be enabled. A PI loop in the program- ming of the control will determine when the full capac- ity compressor output (BO-4) is to be enabled. The compressor must be operating in low capacity for a minimum of 30 seconds before the full capacity com- pressor output can be enabled. During low capacity compressor operation the ECM2 blower will operate in medium speed and will operate in high speed when the compressor is operating at full capacity.

Thermostat Control Mode

In thermostat mode the compressor will be cycled based on Y1 and Y2 calls from a room thermostat. When the control receives a Y1 command (BI-7) from the thermostat the low capacity compressor output (BO2) will be enabled and the ECM2 blower will oper- ate in medium speed. When the control receives a Y2 command (BI-8) from the thermostat the full capac- ity compressor output will be enabled and the ECM2 blower will operate in high speed. During the cooling cycle the reversing valve will be commanded into the “ON” position.
