HL1-KM2-KM3-KA11 Contact configurable as unit operating modes signal (cooling / heating)
The contact is activated in relation to the operating mode set by the room controller A5, by remote cooling/heating input or by the
supervisor.
In cooling mode the contact is closed, in heating mode the contact is open.
The contact configured as "cooling/heating signal" allows management of mixed systems, comprising, for example, radiant pan-
els for heating and fan coils for cooling in summer.
The contact allows the selector valve positions to be changed over so as to bypass the heating storage tank and deviate flow to
the fan coil system.
The contacts hL1, kM2, kM3, kA11 can be configured as "cooling/heating signal" by modifying the following parameters accord-
ingly.
Contact hL1 configured as "cooling/heating signal":
Description
Enable contact as:
0= Alarm signal
1= Dehumidifier
3= Secondary circuit pump
5= Unit operating mode signal
(cooling/heating)
Contact kM2 configured as "cooling/heating signal":
Description
Enable contact as:
0 = System pump
1 = System outlet electric heater,
1 stage
4 = Unit operating mode signal
(cooling/heating)
Contact kM3 configured as "cooling/heating signal":
Description
Enable contact as:
0 = Domestic hot water recirculation
1 = Dehumidifier
2 = Secondary circuit pump
3 = Unit operating mode signal
(cooling/heating)
Contact kA11 configured as "cooling/heating signal":
Description
Enable contact as:
0 = Domestic hot water recirculation
1 = Dehumidifier
2 = Secondary circuit pump
3 = Unit operating mode signal
(cooling/heating)
Contact closed = cooling operating mode signal
Contact open = heating operating mode signal
The "cooling/heating signal" must be configured for only
