PA 1
Evaporator pump/supply fan operation mode
0 = Absent (pump and supply fan are not controlled).
1 = Continuous operation: the pump/supply fan is activated when the
machine is switched on (chiller/h.p. selection).
2 = Working on demand of the compressors: the water pump/supply fan
are linked with the compressors being switched on and off.
PA 2
Compressor ON delay from pump/ supply fan start
PA 3
Evaporator water pump/supply fan OFF delay from when the compressors
are shut off
PA 4
Deactivation Pump Delay from when the unit is Switched Off
PA 5
Pump Activation and Rotation:
0 = No Rotation;
1 = Manual Rotation;
2 = Start Rotation;
3 = Rotation at Hours;
4 = Rotation at Start and Hours
PA 6
Manual Pump Inversion:
0= Pump 1 On;
1= Pump 2 On;
PA 7
No. of hours for forced evaporator pump rotation
PA 8
Simultaneous pump running time after forced pump rotation
PA9
Determines the evaporator water pump/s anti-freeze operation when the
device is OFF or on Stand-by
0 = always OFF in remote OFF or Stand-by
1 = ON, parallel with the anti-freeze heaters
2 = on in remote OFF or Stand-by, depending on the temperature control
request
PA10
Temperature control probe for anti-freeze evaporator water pump/s operation
0 = disabled
1 = evaporator input
2 = evaporator output 1/2
3 = evaporator output 3/4
4 = evaporator output 1/2/3/4
5 = evaporator output 1/2/3/4 and common output
6 = external air temperature
PA11
Evaporator water pump activation set point in anti-freeze mode on the
temperature control probe
PA12
Evaporator water pump differential deactivation in anti-freeze mode on the
temperature control probe
PA 13
Main pump/supply fan timer setting
PA 14
Evaporator no. 2 pump timer setting
PA 15
Hot start set-point
PA 16
Hot start differential
