I've been battling with my contractor for a few weeks now about my new ICP Tempstar 2 stage heat pump and Variable air handler. he chose to zone my house using a ewc bmplus 3000 and 2 ewc URD zone dampers... (2 zones,no bypass) everything was looking good and all insulated properly but, after sending his guys to my house several times they couldnt get it to work right. he left me with one zone operating the entire house. being a handyman and pretty concerned I took the literature and started reading and noticed that the bmplus3000 zone board was not compatible with a 2 stage HP! (I'm thinking this guy and his men are idiots at this point.) I went to ewc website and noticed the ewc uzc4 was the zone panel he should have got. I suggested this to him and he got angry with me...he said it was true that the board was probably the one to use but i shouldnt be concerned about it!! he said he would come back, after a week he said the panel hasnt come in and needless to say he has never come back. unfortunately he got most of his money..but not all of it. now he was also supposed to connect my hydro air on zone 2 and my basboard heat on zone 1 for backup heat sources. I am thinking I need two 3H/2C T-stats to accomplish this but I am a unsure how to go about wiring for the hydro air.. he left the aquastat disconnected and not sure which wires from the thermostat go to it. I am using honeywell zone valves for hotwater heat. I will need a 24vdc relay for auxillary heat for the baseboard.
any comments or direction is greatly appreciated.
