Hello,

In my flat I have 4 "Gabarron RFE Plus" electric radiators, with the following model numbers, where the numbers correspond to how many "modules" or panels the radiator is made up of.

    RF4E PLUS
    RF8E PLUS
    RF10E PLUS
    RF6E PLUS

I have managed to set a weekly program on each radiator with a comfort temperature of 20 and an eco temperature of 18, however, if I touch the radiator when the digital thermostat reads 18 degrees it is stone cold and might as well be off.

I can provide pictures if they will assist!

I don't understand why the radiator thermostat thinks it's 18 degrees but is cold to the touch, can anybody help out here?

Only a "guess" What happens if you raise the "eco temp"

and do these radiators come on anytime? or do you have "economy 7"

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

I'm not on economy 7 and the radiators come on based on the weekly programme I set, so during the week they come on at 14:00 and run in comfort mode (at 20) till 17:30 then they run in eco (at 18) till 22:00.

If I increase the eco temp to 20 then there is some warmth to the touch of the radiator but by no means is it anything close to 20 degrees

Is there any anti hysteresis software built in? I find with my hot water system, the TRV electronic heads start to use anti hysteresis when within 2 degrees of set temperature, so for radiator to get hot the current needs to be two degrees C below target.

Have you tried downloading the manual from the manufacturers website?

Puzzled the 18* and 20* setting is the room area not the panel temp. and perhaps your flat has good insulation and to drop from 20 to 18 takes a while, whilst maintaining room temperature takes only a look-warm rad.

What is the ACTUAL temperature in your room? If it's above 18C then the radiators will be OFF. The temperature setting on the radiators is not the temperature the radiators get to either - they'll get an awful lot warmer than that but will go off as soon as the ambient (room) temperature reaches the set value.

18C in a living room isn't 'hot' (or even warm) by my standards. We keep our living room at 21C minimum to be comfortable.

I have absolutely no idea what the temperature of the room is, I would have to get a thermometer to check but it does make sense that they would go off, I was starting to wonder if it was tracking room temp rather than the panel temperature.

I'll turn it up a degree or 2 to see if it makes any difference :thumbleft:
