Ok I give up.

In my new build, been having trouble with the above & heating. Heating has been staying on outside switching periods, e.g. in the middle of the night.

Got onto developer, and whilst waiting for them contacted Danfoss, who suggested it was faulty TP9000 (TP9000 was turning on heating for a few mins, then turning off). Heating company replaced TP9000 & remote thermostat, on Friday.

Trialled it today, and TP9000 is displaying room & set temperature, as opposed time & date, and there is a symbol displayed, which I can't find anything in the manual about; a thermometer in a house on the right hand side
[I'll post the image in a bit]
My internet research suggests a flashing symbol is signal failure between thermostat & TP9000. Mines not flashing & is hardwired. I'll get the heating company back next week, in the meantime has anyone had this before or has the TP9000?

Can't change display as suggested in manual, to time & date.

Thought it was thermostat mode, but can’t now get into advance settings since the bits were replaced Friday.

I fitted a TP7001 last week at home, that is from the manual.

If you don't have an external thermometer, i.e. actually outside, not just one elsewhere in the house(because you said 'remote', so I'm not sure which one exactly you mean), then this logo is always displayed on mine.

wasn’t there with previous programmer, but thanks for your help
 
Is that symbol stating the temperature showing is the internal temperature and set point?

Can't find the manual that shows the symbols but I do recognise it from the dozens of TP5000 thermostats that I've seen.

Thanks PJ, been staring at the manual and never spotted that.

However, I note it says the override gets cancelled at the next time event, but mine has been staying like that.

I've reverted it back to show time not temperature, and that symbol has disappeared. So fingers crossed. :)
