I hope someone can help me with a central heating problem. I have a Danfoss RF thermostat controller with the Danfoss RX1 unit; noticed this evening that the actual temperature in the house was going up and up, normally I can hear the motorised valve going on and off when the temperature is being regulated but I can't hear it this time. Turning the temp up or down on the thermostat doesn't change anything (the flame icon was going on and off). I changed the batteries as well, still nowt. I then tried to reset the controller (take wheel off, press 'learn' button for 3 seconds) the went to RX1 unit and pressed the CH1 and Prog buttons simultaneously and waited for the green light to appear, but it didn't!!! So question is should I buy a new RX1 unit or spend a fortune and get Swale Heating to come a take a look? Thanks in advance
