Trying to make sense of this... Please if anyone can shed any light it would be appreciated.
I have 4 Salus RT500 receivers, 3 that control the underfloor zones and 1 for the central heating. The Central heating is working fine but since about an hour ago the underfloor has gone cold. The transmitters all have new batteries and are sending the request for heat but when I look at the 4 receivers only the receiver for the central heating is showing red and green.
The 3 for the underfloor have neither red or green lights on which would I guess mean no pwer to these but they all wired to the same control unit and the receiver for the central heating has power Red and Green on. Is it possible that all three receivers have gone faulty at the same time?
