I've had that happen from time to time. I have cleared it by presing the
reset button and removing and putting back the batteries in the receiver.
The other comments about position are also relevent so try moving the
receiver first. It is one of those annoying faults that seems a bit
intermittent and sometimes cures itself!

I have one too! This morning the temperatures were rising very fast indeed.
For no apparent reason the outside remote unit started displaying HH.H and
the indoor unit was flashing 70^c. I got around this problem by giving the
remote unit a good clean. The statements made regarding dashes appearing
when the signal is lost can also apply to when the remote until is at almost
180 degrees to the indoor unit or when the distance between the two is
greater than about 30M.

My batteries always play up immediately following a severe frost. Anything
less than -5^c causes a problem, even with newish batteries.

this is a recognised problem with remote units relying on standard
batteries, the carachteristics of the rf tx frequency at low and high temps
must also be taken in to account.

Hi Pete,

What batteries do you recommend for the remote unit

ideally a permanent dc feed but as this does away with the idea of the
wireless unit this is maybe not practical, its something that davis, oregon
and others have been working on for some while, the low power of their tx
unit being in milliwatts also does not help matters.
