Sorry guys, I've been doing a lot of reading on other threads but still can't quite get this right in my head.
I got 2 new thermostats to use on my system, the existing one was such a PITA to program I just replaced it.
OK, so thermostat #1 (which should run the existing gas furnace) has 4 wires coming into it, Red, Yellow, White, and Green. Thermostat #2 (which should basically just allow the fan to run without firing the gas furnace) is a heat-only thermostat with just 2 wires running from thermostat #1, Green wire on #1 to the White terminal on #2, and Red on #1 to Red on #2.
I got this wiring setup directly from the Central Boiler website and instruction manual, got it all hooked up the other day just how they explained it. I don't have the OWB quite ready yet so I went to fire up the gas furnace just to test it and make sure it was going to work and serve as the backup eventually. Well, when it took off it seemed to work, but the A/C unit also came on, which definately threw me off. So I guess that's my first question, what did I mess up there and can I make it work how I have it set up without a bunch more wiring or extra relays?
OK so here's my next dilemna, while trying to just run the gas furnace, I left thermostat #2 in the OFF position and tried to run the furnace with just thermostat #1. Not much luck there, the blower wouldn't come on, so I turned thermostat #2 on and dialed the temp up on it, which allowed the gas furnace to operate normally, except the blower kept running after it quit firing on gas since the temp setting on #2 was a bit higher than #1. Once again, is there something I messed up here, or is there a way to operate the system with just the one thermostat?
Sorry if I sound like a complete bonehead here guys, the mechanical part of this whole OWB setup has been real easy for me, but this whole thermostat thing is driving me nuts. I think I can make it work, I just want to make sure it is working as it should, and of course safely, thanks for any input guys!
