Hello Experts,
hoping this is easy to understand.
Last year it was no problem, but this year we seem to have lost one of our Ecodan heating zones.
Zone 1, configured as Underfloor heating
Zone 2, configured as Radiators.
We have lost Zone 1 for the underfloor heating, zone 2 radiators and the DHW all work fine. The zones are controlled by Siemens RF100 RF thermostats, I have swapped the thermostat transmitters/receivers around but they don't seem to be the fault and when trialing the zone 1 thermostat, the moment the 'call to heat' comes on I can hear the relay in the receiver actuate closed and the green connection light on the receiver illuminates, when I spin the dial to 'call for no heat' I hear the receiver relay open, green led goes out, again I have interchanged the RF thermostat transmitters and receivers but the problem remains on the zone 1.
To add to the mystery, I think it has been missing since we had a service on the system, so suspiciously I think it has been erronously disabled.
I have tried to get the technician back for some time now but is ignoring my calls and messages. On our system we have the main remote controller yet it only looks as if the one one is active. I have been through the ROOM RC ZONE SELECT settings but I never seem to have the option or control of a second zone.
I can't be sure but have a feeling the problem is with the setup rather than a failure, any ideas or an Engineer to visit and set would be most welcome. postcode CH7. Many thanks for any advice. Kind regards
