SEQUENCE OF OPERATION
Space/Room Sensor Control Compressor Operation
Compressor Operation
Compressor(s) will only operate if the Supply Fan has been
Cooling Mode is enabled when the Space Temperature rises
above the active Cooling Setpoint (default: 74°F) plus the
when the Space Temperature falls below the active Cooling
Setpoint minus the deadband.
Heating Mode is enabled when the Space Temperature falls below
the active Heating Setpoint (default: 70°F) minus the deadband
the Space Temperature rises above the active Heating Setpoint
plus the deadband.
Compressor staging up and staging down are subject to the
following setpoints:
• Compressor On Delay
(5 seconds, non-adjustable)
• Compressor Minimum On Time
• Compressor Minimum O Time
• Compressor Interstage On Delay
• Compressor Interstage O Delay
If the unit goes into an alarm, the minimum on time of the
compressor(s) will be ignored and the compressor(s) will be
disabled.
On/Off Compressor (Scroll or Rotary)
In Cooling or Heating Mode, the compressor will be enabled.
There is no Supply Air Temperature Control.
Multiple Stage Compressors
Stage Up Sequence
In Cooling Mode, as the Supply Air Temperature rises above the
compressor(s) will stage up. The compressors will operate on
a PID loop function. Once the PID loop calls for the next stage
to be on and the Compressor Interstage On Delay time has been
met, the next stage of cooling will be enabled.
In Heating Mode, as the Supply Air Temperature falls below the
compressor(s) will stage up. The compressors will operate on
a PID loop function. Once the PID loop calls for the next stage
to be on and the Compressor Interstage On Delay time has been
met, the next stage of Compressor will be enabled.
Stage Down Sequence
In Cooling Mode, as the Supply Air Temperature falls below the
down delays allow.
In Heating Mode, as the Supply Air Temperature rises above the
down delays allow.
