r3 Operating mode

The controller can work as a thermostat and defrost controller (r3 = 0), or as a simple thermostat in direct operation (r3 = 1), or as a simple thermostat in Reverse- cycle operation (r3 = 2).

Default setting: r3 = 0.

r4

Automatic variation of the set point in night time operation.

 

Default: 3.0. Not used by Foster

r5

Enables minimum and maximum temperature monitoring.

rt

Effective interval for monitoring the maximum and minimum temperature.

rH

Maximum temperature measured in the interval rt.

rL

Minimum temperature measured in the interval rt.

 

These parameters are used for recording the temperature. Not used by Foster.

c0

Compressor and fan start delay (if fan relay present) on start up.

 

When the controller is switched on the compressor and evaporator fans start after a delay (in minutes)

 

equal to the value set for this parameter.

 

Default: c0 = 0.

c1

Minimum time between two successive starts of the compressor.

 

Sets the minimum time (in minutes) that must elapse between two starts of the compressor irrespective of

 

the temperature and the set point. Setting this parameter limits the number of starts per hour.

 

Default: c1 = 0. Foster setting c1 = 1.

c2

Minimum compressor OFF time.

 

Sets the minimum time (in minutes) that the compressor must remain OFF. The compressor is not started

 

again until the minimum time selected (c2) has elapsed from when it last stopped.

 

Default: c2 = 0. No minimum OFF time is set.

c3

Minimum compressor ON time.

 

Sets the minimum running time for the compressor.

 

Default: c3 = 0. No minimum running time selected.

c4

Duty setting

 

If the virtual control probe fault alarm occurs (indicating a probe fault) the compressor unable to operate

 

based on temperature will run on a timed bases equal to the value set in c4 with a fixed OFF time of 15

 

minutes.

 

Default: c4 = 0 minutes. Foster setting c4 = 80 minutes.

ccContinuous cycle duration.

The time (in hours) that the compressor operates continuously to lower the temperature, even below the set point

Default: cc = 0 = the continuous cycle is disabled.

c6 Alarm bypass after continuous cycle.

The time in hours that the temperature alarm is deactivated after a continuous cycle.

Default: c6 =2 hours.

c7 Maximum pump down time. Not used by Foster.

c8 Compressor start delay after opening PD valve. Not used by Foster.

Default: c8 = 5

c9 Enable autostart function with PD operation. Not used by Foster

Default: c9 = 0

c10 Select pump down by pressure or time. Not used by Foster

Default: c10 = 0
