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?

I have a iPhone 8

I have a tiled floor in kitchen which we would like to warm up, to take chill off the tiles 8am to 10pm 7 days a week

The instructions say press down and pull towards you but I cant get it to budge and I dont want to break it before I start.

I have set as room sensor but this is incorrect

What type of cable is required to extend both heater & sensor cables.

We are nearly eighty years old and both have health problems
Many Thanks in anticipation you may be able to help.

can i use the mat heater onto on the insulated concrete slab which has already been laid before the final 50mm levelling pour is put on
