Alarm Stop
control the minimum time the compressor has to be stopped
before being started again after an alarm.
The
Anti Block
timer is used when deciding if the compressor should be
started even if the low pressure has not reached minimum level. It is also
used decide for how long we will wait for the low pressure to reach its
shutoff level before stopping the compressor anyway.
Wakeup Mode
timer controls for how long the compressors needs to be
inactive and we will start the compressor in wakeup mode. In wakeup
mode, the valves will be open for a longer time before closing them
according to demand. We do this to settle the refrigerant after a long time
of inactivity.
Wakeup Time
timer controls for how long all valves will be open when
the compressor is in wakeup mode.
SucTempL Dly
is the debounce delay timer for the low suction
temperature alarm.
SucTempH Dly
is the debounce delay timer for the high suction
temperature alarm.
DisTempL Dly
is the debounce delay timer for the low discharge
temperature alarm.
LP Alarm
pressure setting controls at what Low Pressure level
compressor will trip on Low Pressure alarm once it is past Stabilize state.
LP Start
pressure setting controls at what minimum Low Pressure level
compressor will start. Note that there also are some timers controlling
when compressor can start (Min Startup and Anti Block).
LP Max
pressure setting controls the maximum Low Pressure level we
allow the compressor to run at. A check against this level is done
intermittently defined by Fault Delay timer.
HP Min
pressure setting controls the minimum High Pressure level we
allow the compressor to run at. A check against this level is done
intermittently defined by Fault Delay timer.
HP A/C
pressure setting controls at what High Pressure level Outdoor Air
Condenser will start if any compressor A/C valve is open.
LP Pumpdown
pressure setting controls at what Low Pressure level
compressor will do an idle pump down when compressor is not running.
