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
