Plumb center heat demand icon not displaying (but heat comes on ok)

[Ajay80]

Hi, my plumb center wireless room thermostat has stopped displaying heat demand icon when heat is on.

I have changed batteries and completed a re-bind but no luck. I can still turn the heat on ok with thermostat, it's just that the display doesn't tell me I have done so!

Any help would be greatly appreciated

Other than the old trick of leaving the batteries out for a long time (say an hour), to ensure it boots up properly from scratch when you put the batteries back, I don't think there's much more you can do.
You can use it and ignore the lack of icon,
or buy a new one!

Another possibility would be to do a full reset, see installer instruction for how, which would then need all the times / temps re-entering.
However I can't see that affecting something as basic as the Heat demand symbol.
