Secondary circuit flow temperature sensor
Contact humidistat 24 V
–
Note
If a 230 V~ contact humidistat (connection to X3.8/X3.9) is used
for cooling, insert a jumper, otherwise the heat pump will not
start (message "CA Protectn device primry").
Note
System with heating water/coolant buffer cylinder:
If cooling is performed via several heating/cooling circuits, pro-
■
vide a contact humidistat for each heating/cooling circuit.
Connect several contact humidistats in series.
