Foster RBC20-60 - Parameter Definitions: System & Other Details; System Parameters (P66-P78)

15
P53 Hold Temp Std
The standard temperature, which the air probe must read before the condensing system is de-energised in the
Hold mode of the Professional 3 Program.
Range -15°C to 15°C.
P54 Hold Temp Minimum
The minimum value that the Hold temperature set point can be adjusted to by the operator in the Professional 3
program.
Range -10°C to 0°C.
P55 Hold Temp Maximum
The maximum value that the Hold temperature set point can be adjusted to by the operator in the Professional 3
program.
Range 0°C to 10°C.
P56 Change Time
The percentage period of a time based chill cycle, which is to have passed before automatically adjusting the air
temperature set point to 1°C.The range is adjustable in 5% increments.
Range 05% to 95%.
P5
The percentage of a temperature based chill cycle, which is passed before automatically adjusting the air
temperature set point to 1°C.The range is adjustable in 5% increments.
7 Change Temp
Range 5% to 95%.
System
P58 UV Light Enable
Determines whether the user can select the UV sanitisation.
Minutes 0 = disabled, 1 to 120 = enabled (set the time between 1 and 120 to determine the length of the
program).
P59 HACCP Enable
Determines whether the logging system is available to the user.
Function, YES = enabled. NO = disabled.
P60 Shock Freeze Temp
Allows for the probe to be used in the Shock Freeze mode.
Function, YES = enables. NO = disables.
P61 Chill Hysteresis
Allowable temperature increase from chill cycle air temperature Set Point before switching on the refrigeration
system.
Range 02°K to 20°K.
P62 Hold Hysteresis
Allowable temperature increase from hold cycle air temperature Set Point before switching on the refrigeration
system.
Range 02°K to 20°K.
P63 APM Time
Automatic Program Mode Time. The time period that must pass before the air temperature and Food Probe 1
temperature are compared to determine whether the cycle is time or temperature based.
00 = Instantaneous decision. 01 to 30 = the time selected determines the start time decision.
P64 APM Differential
Automatic Program Mode Differential. The difference in temperature between the air temperature and food probe
1 temperature after APM time to determine whether the cycle is time or temperature based. If air probe
temperature + the APM differential is greater than or equal to food temperature the chill cycle will be time based.
If air probe temperature + APM differential is less than the food probe temperature the chill cycle will be
temperature based.
Range 0°K to 20°K.
P65 FAN 1 Hold Operation
Determines the evaporator fan relay energisation during ‘Hold’ mode.
‘OFF’ = Evaporator fan 1 relay is not energised in ‘Hold’.
‘CYCLE’ = Evaporator fan 1 relay cycles with condensing system relay in ‘Hold’.
‘AUTO’ = Evaporator fan 1 relay cycles with condensing system and fan hysteresis in ‘Hold’.
‘ON’ = Evaporator fan 1 relay is always energised in ‘Hold’.
