Description
Temperature at which the lead compressor will switch on.
Differential temperature below the cut-in temperature. The lead compressor switches off when below this
temperature
Percentage of the Air-On temperature that is used to calculate the control temp. The remaining
percentage will be used on the Air-Off temperature
Example, P-03 set to 30%
Control temp = 30% Air-on + 70% Air-off
As above only applied to the display temperature
Delay before the second compressor is switched on if the temperature is still above set-point.
Note – The lead and lag compressors swap after each defrost to even the run times.
Allows the user to set the compressor for a given number of starts/hour
Diff below the Cut-In Temp the lag compressor switches off.
Single Compressor Operation
To disable compressor B operation and use only a single compressor for control set parameter P-07 to 0.
This will allow the controller work with just one compressor (A) and ignore compressor B.
Allows the keys switch to be: -

Single turn for case off (Case off mode)

Single turn for Fans only (Fans Mode)

Single turn for case off, double turn for fans only (Toggle mode)
Switches between using the air-on probe and the Logging probe. Note the control and display
temperature will still be a derivative of the weighted
Average of the control probe + Air-off probe
Turns on/off the switched resistor case off function
Allows the user to set the fans to turn off when: -

A pre-determined temperature is reached (P93)

When an over-temperature alarm is present

When either P93 is reached or an OT alarm is present
Temperature for the above (P92) operation. Note the defrost termination probe is the source of the
temperature reading used in this feature. If the defrost termination probe isn't fitted then a similar process
to P-44 is used.
