Par. ST04 Heat pump setpoint
It allows to set the Heat pump working temperature within the range ST05..ST06.
Par. ST05 Minimum setpoint limit in heat pump.
The user can not program a setpoint value lower than ST05, the range is –30 °C..ST04.
Par.
ST06 Maximum setpoint limit in heat pump
The user can not program a setpoint value higher than ST06, the range is ST01..70°C.
Par.
ST07 Regulation band width in chiller mode.
The configured resources are distributed inside the regulation band.
Example Unit configured with 2 circuits, 3 compressors per circuit and thermoregulation controlled by the evaporator inlet NTC probe.
Chiller setpoint: evaporator inlet water = 12°C, evaporator outlet water 7°C: when the evaporator inlet water is 12°C all the compressor
outputs are on while when the evaporator inlet water is 7 °C all the compressors are OFF.
Thermoregulation parameters: Par. ST01 = 7 °C / Par. ST07 = 5 °C
Functioning : the regulation band ST07= 5 °C is divided by the number of resources 6 compressors therefore the step for each
resource is 0.8°C, each 0.8°C if the temperature is increasing or decreasing one of the resource is turned on or off.
Par.
ST08 Regulation band in heat pump mode
The configured resources are distributed inside the regulation band.
Example Unit configured with 2 circuits, 3 compressors per circuit and thermoregulation controlled by the evaporator outlet NTC probe.
Chiller setpoint: evaporator inlet water = 40°C, evaporator outlet water 45°C: when the evaporator outlet water is 40°C all the
compressor outputs are on while when the evaporator outlet water is 45 °C all the compressors are OFF.
Thermoregulation parameters: Par. ST04 = 40 °C / Par. ST08 = 5 °C
Functioning : the regulation band ST08=5 °C is divided by the number of resources 6 compressors therefore the step for each resource
is 0.8°C, each 0.8°C if the temperature is increasing or decreasing one of the resource is turned on or off.
Par.
ST08 Regulation band in heat pump mode
The configured resources are distributed inside the regulation band.
Par.
ST09 Defines the thermoregulation probe in chiller.
0= NTC Temperature probe of the evaporator inlet
1= NTC Temperature probe of the evaporator circuit #1
2= NTC Temperature probe of the evaporator circuit #2
3= NTC Temperature probe of the common evaporator
4= Probe temperature of the remote front panel #1.
5= Probe temperature of the remote front panel #2.
The
ST10 parameter defines the thermoregulation probe of the unit with heat pump control
0= NTC probe temperature of the evaporator inlet
1= NTC probe temperature of the evaporator #1 outlet
2= NTC probe temperature of the evaporator #2 outlet
3= NTC probe temperature of the evaporator common outlet
4= Remote terminal # 1 probe
5= Remote terminal # 1 probe
6=
NTC probe temperature of the condenser common inlet
7= NTC probe temperature of the condenser # 1 inlet
8= NTC probe temperature of the condenser # 2 inlet
9= NTC probe temperature of the condenser # 1 outlet
10= NTC probe temperature of the condenser # 2 outlet
11= NTC probe temperature of the condenser common outlet
ATTENTION
To have the same regulation both for chiller and heat pump set the parameters ST09 and ST10 with the same value
22 SELECTION OF THE KIND OF THERMOREGULATION
Par. ST11 determines the type of regulation
0= Proportional
1= Neutral zone
2= Proportional integral
