I have a wiring question. I am trying to install a Honeywell EIM and HZ432 zone control panel to my existing heating/cooling system. The system is set up as follows: The boiler (which feeds eight zones throughout the house with radiant loops and cast iron stand up radiators) has on zone dedicated to a fan coil which is located in the duct that feeds one hydro-air zone. The hydro-air zone is controlled by a Carrier AHU that also provides AC. The Carrier AFU has four zones - one heat & AC and three AC only zones. I need to wire the EIM and HZ432 zone panel so when the thermostat calls for heat the circulator pump starts and when the Aquastat is satisfied that the water at the coil is at the right temp. the fan comes on. The coil is a fair distance from the boiler and I don't want to start the fan until the coil is up to temp. I also want to have the fan work properly when "fan only" in selected at the T-stat and have it wired so it works properly with the AC. I have the following equipment. Honeywell Aquastat that is Normally Open Taco Circulator pump wiring into relay board w/24v transformer power Carrier AHU Honeywell EIM Honeywell HZ432 Zone Panel Honeywell THX9321 Prestige Thermostat There is also a Honeywell R8222 relay mounted to the plenum that is currently not be used, but tests as working. Any help you guys can offer would be appreciated.

Hello everyone, Not sure if this is the right sub-forum so mods feel free to move if need be. My house (around 2500 sq/ft, one story) has two electric heat pumps / central air conditioning units and two thermostats. One thermostat controls one unit and the other controls the other unit. They are set up to basically split the house down the middle longways. One thermostat is mounted in the hallway which is logical and fairly central to the house but the other thermostat is mounted in a back bedroom which works but is kind of inconvenient. I also notice somewhat uneven heating and I am guessing it is due to the 'inconvenient' thermostat sending signals from an unused back bedroom instead of a central spot maybe? Would it make sense to relcoate the 'inconvenient' thermostat to the hallway too or should I just leave it there? Is there something else to consider in this project I am overlooking? Thanks for any input or thoughts.
