The red light is on and the heating is not working. We have tried resetting but to no avail. How can we fix this?

Can the room sensor be used to replace existing mechanical gas Central Heating thermostat, and the floor sensor connect separately to electric underfloor heat mat? Thanks, Tom

Have c16 with 10m matt but not going higher then 14.5, can you please help

Do we need to change both? The temperature readings keep changing every few seconds

We have 2 Intelligent Controllers serving the underfloor heating under our large tiled kitchen floor. Both have been set to identical Custom programs (Period 1 with initial on at 7.00am and off at 9.00pm 7 days a week). However, one of the controllers doesn't seem to conform to the custom program timings and operates continuously. This is irrespective of the temperature - for example with a Custom temp of 23 degrees the heating remains on at midnight when measured temp is 19 degrees. Is it possible taht the controller has been wired in such a way as to by-pass the program settings or could there be another explanation?

Inside bathroom or outside bathroom?

How can I adjust the setback temperature? The option is mentioned in the manual but not available. By default the setback temperature (temperature of the floor outside of the comfort periods) is 5 degC lower than the comfort temperature. I want to stop the floor using *any* power during peak periods since I'm on a dynamic rate electricity tariff. Is this possible? This is a basic thermostat function.

I tried suggestions as touching both square and arrow up (only locks the settings) and both arrow up and arrow down, this gives code F1 - what does this mean?

I just want to turn it on and off when I need it

I had the heating on constantly using the old FHT. Now in manual mode I raise the set point temperature and it seems to reach this quickly and switch off heating but the floor is not as warm as I would like. Is there a recommended setting for constant ‘background’ for the set point figure?
