Water pressure 01.03.2020 09:44 04.03.2020 17:54

Monitoring the pressure of water in the heating circuit (monitoring any leakages) can be done using a pressure switch with a contact output, e.g. the Presostat KPI 35 (order number 060-121766) DANFOSS, or the 61214 ZPA EKOREG.

The Presostat KPI 35 enables setting the pressure range, within which the unit sends a signal, i.e. a differential pressure, when the contact system switches the contact on and off. The output changeover contact should be connected to the binary system input, e.g. the C-AM-0600I module.
