hi,
i have replaced my 16 year old honeywell thermostat with a heatmiser prt-ts. it is to control a combi boiler.
i wired the red to L, the blue to N, the yellow to A2 and added a wire from L to A1. i think this is right according to installation diagram...however when i switched the power back on the heatmiser unit is completely dead.
I was wondering if anyone else has had this problem, or if there is something i have to do to switch the unit on?
thanks,
phil
