one of the AC units in my home has a 3 zone controller (built in 2007) and i think its bad (one thermostat went blank, that zone is dead, tried another thermostat and still dead, have 24vac at thermostat and wont even turn on)
looking at a more modern controller and have come up with a Honeywell HZ311 or HZ322 and would like some advice before i purchase
this unit is a 5 ton carrier, 3 zones and has a bypass damper and three in line vent controllers
please PM if i could call you with questions
