20 AUXILIARY RELAYS
The auxiliary relays can be configured to manage two independent, from heat pump or chiller mode, output controls.
Each output can be managed with a dedicated temperature or pressure probe input ( NTC probe, 4..20mA or 0..5V transducers) or with
the common available temperature or pressure configurable inputs.
The probe selection is made with parameters uS02 for the circuit 1 and uS06 for the circuit 2.
The function is enabled when the parameter uS01 <>0 for the circuit 1 and the parameter uS05<>0 for the circuit 2 and at least one
output is configured as auxiliary output.
Par.
uS01 configuration auxiliary relay 1.
Par. uS05 configuration auxiliary relay 2
Value and function
0 = Not enabled
1 = Function enabled, direct action, also during stand-by or remote off.
2 = Function enabled, direct action, only with unit running.
3 = Function enabled, inverse action, also during stand-by or remote off
4 = Function enabled, inverse action, only with unit running.
20.1 A
UXILIARY RELAY WITH
D
IRECT ACTION
When:
PBr < set : relay ON.
Pbr > set + differential: relay OFF.
Set < PBr < set + differential: previous status.
PBr = NTC probe or transducer selected by the parameters uS02 / uS06
20.2 A
UXILIARY RELAY WITH INVERSE ACTION
When:
PBr > set : relay ON.
Pbr < set - differential: relay OFF.
Set – differential < PBr < set: previous status.
PBr = NTC probe or transducer selected by the parameters uS02 / uS06
If:
PBr > SET: relay ON
Pbr < SET– differential: Relay OFF
Set – differential < of PBr < SET: previous state
PBr = NTC probe or transducer selected with uS02 / uS06 parameters
21 COMPRESSOR THERMOREGULATION
21.1 THERMOREGULATION PARAMETER DESCRIPTION
Par. ST01 Chiller Setpoint
It allows to set the chiller working temperature within the range ST02..ST03.
Par.
ST02 Minimum setpoint limit in chiller.
The user can not program a setpoint value lower than ST02, the range is –30 °C..ST01.
Par.
ST03 Maximum setpoint limit in chiller.
The user can not program a setpoint value higher than ST02, the range is ST01..70°C.
