Room Stat Overides Programmer

I have installed the above room stat and programmer, however the room stat overides the programmer, basically when the heating is not on the time for it to be on ( as normal ones work ) it comes on if the tempreture drops below the room stat set figure. Therefore the room stat calls for heat and it fires even when its out of programmed time. I have had both my electricians look at it and they both thought the product was faulty therefore i changed it for a new one and the same happens, there completely cluelss and theres no way it should happen. No doubt there is a very simple explantion but we dont have one. Has anyome else had this problem ?/? there appears to be no info on this issue online either.

It sounds like its working as a frost stat ,which will fire the heating when the temp drops with the heating not being on , this to stop house from freezing up .

Danfoss rx1 thermostat shows 'of' ?


Remove batteries from room stat,turn off the electrical supply to reciever unit.
Turn back on the electric to reciever unit,the red light should be on,press the top "manual" button,the green light should come on and boiler should fire (assuming the programmer is in an "on" period)
Press the bottom button,and keep it pressed,then press the top button until the green light flashes,stand about 6 feet away,and refit the batteries to the stat while observing the reciever unit,either the red or green light (cant remember which) should flash to show the 2 units are syncronised.

Another basic test if all seems ok,when turning the stat up or down,when the green light on the reciever unit comes on or goes off,its usually accompanied by an audible "click" ive found,that if this is not happening, the reciever unit does not switch either on or off,may be intermittant.
Replacement is the only cure.

Disregard wire colors. Instead wire by terminal designation. In other words :
Wire on "R" Terminal on old thermostat to "R" Terminal on new thermostat no matter the color.

The heater is not coming on. fan will blow cold air but does not heat up.


Assuming you have the T-stat set to the heat setting and set at least 10 degrees above room temperature and have the t-stat set to AUTo (If applicable) then the problem is with the actual heating unit. The T-stat merely turns the unit on.

Cannot set heat setting by using "hold" feature


make sure it is not telling you room temp, some of the Honeywells, will display room temp over desired temp. check that, if it wont let you switch temp than buy a new one, if you dont have a heat pump a new cheap stat is around 20.00.
