12-20-2006, 03:32 PM
I'm looking for a DPDT Duct Stat with up to a twenty degree adjustable differential between the switches, 120VAC, Pilot duty. What I'm trying do. I have a 100% MAU, with a heat exchanger coil in the end of it, that picks-up/discharges heat to/from the Exhaust fan. The Air handler, has a heating and cooling coil with modulating Valves and Discharge Air Thermostats. I want to lock-out the Heating above 55F O.A. and lock-out the cooling below 75F O.A.

Honeywell has the T7079A single stage electronic temperature controller that has a maximum stage differential of 30 degrees. There is also the B model that has two outputs with a maximum interstage differential of 35 degrees.

Thanks for the info, I will print that out and check on the price. Like the remote feature as that will put all the controls together. I'm also checking on some Barber Colman reset sensors that hook to their 8300 series thermostats.
