Thanks slimjim. I'm from "up here" in Canada. I don't have a heat pump. Also, not sure if I could draw it because I don't know what wires or parts I need. But I can try to explain.
1 - there is a pump that circulates the water to the OWB (and domestic hot water sidearm). This runs 24/7. Temp is controlled by the Aquastat on the boiler. I don't want to change any of this.
2 - There is a second pump that circulates water through a plenum in a duct in the furnace. This is currently wired to run 24/7 until I get this figured out.
3 - there is my original oil furnace. There boxes on the front of the furnace that have a switch on each. Switching them manually, one turn on a low speed fan, the other a high speed fan. This was all there prior to the OWB install.
4 - I currently have one thermostat with two wires going to the furnace. From what I can tell, this only turns on the high speed fan, and oil.
What I would like is as follows:
1st Stage Heat: Furnace Fan Low, Plenum Pump On, Oil Off
2nd Stage Heat: Furnace Fan High, Plenum Pump On, Oil Off
3rd Stage Heat: Furnace Fan High, Plenum Pump On, Oil On
1st Stage Cool: Fan Low, Plenum Pump Off, Oil Off
2nd Stage Cool: Fan High, Plenum Pump Off, Oil Off
No I don't have A/C, but my basement gets really cool in the summer and I currently turn on the furnace fans manually to cool the house.
I think the kicker is that I only want one (two at most) Programmable 7 day Thermostat(s) to do it. I really just need to understand most of how to do this so that I can explain it to my electrician. Especially what thermostat will work, and how. No one around here has every done anything with multi-stage heating so when I tell them about a thermostat like TH8320WF, I get a blank stare.
Any suggestions, literature, websites, would be greatly appreciated.
