We have a Rheem furnace (RGPL), a Ruud heat pump (UPPA), and a Honeywell VisionPro 8000 thermostat (not sure specifically which model). The system install was a saga that took place from Nov '05 through April '06. Somehow, the original installer found a heat pump that'd been in someone's warehouse for over a year and put it in at our place. After original GC quit, I had to bring in a 2nd company to finish the system.
I'm trying to understand better how it's set up, mainly to see if I can adjust where the second stage is called for and avoid a service call. I was home yesterday, while the outside temp was ~40F and noticed that the gas heat was running. Having gotten what I thought was a pretty good electric bill last month, I was surprised to see the gas bill come in higher than expected. Guess that's why.
I've looked through the VP setup some, and I believe there's also a dual fuel kit (that's what the memory register for that option says, anyway). My understanding from reading here is that the VP should be able to handle this function.
So, here are my questions:
1) How can I find out where the switchover between stages is set and adjust (the temp down, presumably) if necessary? I honestly don't know what the dual fuel kit looks like, but I assume it's a board mounted at the furnace.
2) Would it make more sense to have the VP run the dual fuel setup? This is probably within my capabilities, with some guidance. At the least, it'd be nice to have an outdoor temp indicator at the VP, which isn't there now. Seems like this is a signal coming in from the heat pump that could be passed on to the VP, or would I need a separate sensor?
