20.2 COMPRESSOR TEMPERATURE CONTROL IN HEATING MODE
The Par.
ST10
defines the probe for unit temperature control (if ST12= 1 just of circuit n° 1) in heating
working mode
0= Evaporator inlet NTC temperature probe
1= Evaporator n° 1 outlet NTC temperature probe
2= Evaporator n° 2 outlet NTC temperature probe
3= Evaporator n° 3 outlet NTC temperature probe
4= Evaporator n° 4 outlet NTC temperature probe
5= Evaporator common outlet NTC temperature probe
6= n° 1 remote terminal temperature probe
7= n° 2 remote terminal temperature probe
8=
condenser water common inlet NTC temperature probe
9= circuit n° 1 condenser water inlet NTC temperature probe
10= circuit n° 2 condenser water inlet NTC temperature probe
11= circuit n° 3 condenser water inlet NTC temperature probe
12= circuit n° 4 condenser water inlet NTC temperature probe
13= circuit n° 1 condenser water outlet NTC temperature probe
14= circuit n° 2 condenser water outlet NTC temperature probe
15= circuit n° 3 condenser water outlet NTC temperature probe
16= circuit n° 4 condenser water outlet NTC temperature probe
17=condenser water common outlet NTC temperature probe
WARNING
If the same temperature control is required in cooling and heating working mode, set the same value in the
ST09 and ST10 parameters
20.3 TEMPERATURE CONTROL ON TWO INDEPENDENT CIRCUITS
The Par.
ST12
enables the temperature control logic on two different circuits
0 = unit temperature control
1 = temperature control on two separate circuits, circuit n° 1 and circuit n° 2
•
If
ST12 = 1
and circuit n° 2 is enabled with at least one resource configured, temperature control
takes place for circuit n° 1 with parameters ST01 / ST10 for circuit n° 2 with the same logic with
parameters ST13 / ST22
21. CHOICE OF THE TYPE OF TEMPERATURE CONTROL
Par
ST11
Defines the type of unit temperature control
0= Proportional
1= Neutral zone
2= PID
