I have a Honeywell RTH7000 Thermostat and a heat pump and gas furnace. When the heat pump cannot keep up with the heating (ie temp more than 3 degrees lower than setting), the thermostat tries to run the heat pump and the furnace at the same time. Is there a setting to prevent that?

I am providing you with the manual for your unit. It is difficult to find things out when you no longer have the manual. It covers your question. See page 18 setup

Thanks!
I do have the manual, but it was not clear on function 170, if I should use setup 7 or 8 (the tech chose 7). I do have the gas furnace on w2 (heat pump on w), so I tried 8. It seems to be correct. There is a jumper from e to w2, I cannot find the purpose of this in the manual, but I assume it connects emergency heat to the furnace on w2, which is what I want.

The jumper sounds good. Is it working OK now? 7 seems correct.

There will always be questions. LOL
