ive had a hive thermostat installed getting rid of the old honeywell timer. the wiring was a straight swap. there is one cable coming from the unit on the top left to another honeywell unit. is this one required?
the plumber left it in. but now and again i have to reset it if the heating stops working and then its fine again.
cheers
