FCAx3 USER MANUAL
32 +44 (1753) 214 500
The number of controller start-ups, in which the Compressor Relay OFF Protection Delay will be ignored. This will result in the
compressor turning ON as soon as the FCAx3 is powered up.
Note: The Compressor Relay OFF Protection Delay will still be respected during operation.
Delay Between Loads
The minimum time delay between one relay turning ON and another being allowed to turn ON.
Min Compressor On Time Before Cut-out
The minimum duration the compressor must be ON before being allowed to turn OFF even if the temperature drops below the
set cut-out value.
Min Compressor Off Time Before Cut-in
The minimum duration the compressor must be OFF before being allowed to turn ON even if the temperature rises above the
set cut-in value.
Note: Compressor OFF Time must be satised when the compressor switches off due to the temperature only. Compressor Off
Protection Delay and Compressor Off Time must be satised in this instance so the controller will remain off until the timer with
the longest set time has elapsed.
