Accepted values are 1 to 4 and Tandem.

Refrigerant

 sets the type of Refrigerant used in the system. This will 

affect some of the pressure levels used to control the compressors.

Oil Alarm

 sets if the system supports Oil alarms. Note! This feature is 

currently not implemented but will be very soon.

Use the 

Partial Mode

 property to control if unit will be using partial 

heating mode for compressors. Partial heating mode is when both the 
reheat and the A/C valves are open. When this property is set to No for a 2 
compressor unit, there still is a partial heating stage when both 
compressors are running where one compressor is running in full reheat 
and the other compressor is running in full A/C. The only thing this 
property is preventing is that one compressor have both valves open at the 
same time.

The 

Mode Transit

 property should only be changed after talking to a 

Seresco engineer. It is used to solve a problem where a solenoid valve is 
not closing properly. Using this timer will close both solenoid valves when 
one valves needs to be closed. After timeout, the other valve is opened. 
Typically you will not set this one to more than 3 seconds.

Set this property to 0 to disable this feature.

Min Startup

 timer controls the minimum time compressor will wait 

before starting compressor even if minimum Low Pressure level is met.

Stabilize

 timer controls for how long time the compressor will run before 

we enable the Low Pressure alarm. During this time the system will still 
monitor for a low pressure level reaching vacuum levels using the low 
pressure transducer.

Fault Delay

 timer controls the time between each check to see if Low 

Pressure is below maximum allowed and High Pressure is above minimum 
allowed. Timer starts when compressor starts and then after every check 
for as long as compressor is running.

Min Run Time

 timer controls the minimum time the compressor has to 

run before it can be stopped.

Min Stop Time

 control the minimum time the compressor has to be 

stopped before being started again after a normal stop.
