Set-up
22: Liquid subcool
0 to 99.9°C
Enter a value for the compressor Liq.subcool using the formula ΔT~Tc,sat-T3. Only valid if
COP active = Yes. See the Unisab III COP manual for further information.
23: PMS feedback fixed
No
Yes
Select No if you want the PMS feedback input to be set up as a pulse feedback signal. In this
case the signal can be removed during operation without stopping the compressor.
Select Yes if you want the PMS feedback input to set up as a fixed feedback signal. This may
be used for e.g. pump control function. In this case the signal cannot be removed during op-
eration without stopping the compressor. If the PMS feedback gets off (after having been ON)
a PMS error shutdown is given.
