Micro-Air thermostat question? 2017 View

[TimothyPaul]

Good Morning - 2017 View, stock air and furnace. Wondering if this is the correct setup for a MicroAir 345 Thermostat ? If so, when would you choose furnace and when would you choose heat pump? Is it a matter of preference, or is there a correct way to run it? Florida guy here, so when I installed it, all I was concerned about was A/C, now that I decided to go up north, I am questioning my lack of preparation ! Lol. ….

A couple of things to know about heat pumps.

1. They are your A/C running in reverse. And they will put out warm air from your A/C vents in the ceiling. They work pretty well but only when the weather outside is above the mid-to-high 30's. Otherwise they are not able to provide heat. Obviously, they use electricity and are used when on shore power... just like A/C.

2. Your Furnace is propane fueled, runs on 12v battery power and the warm air comes out of the floor vents.

When to use which is up to you as long as the outside temps are about 40 degrees or higher. Or when you don't have shore power. Or when you have plenty of Propane and battery power to power the furnace fan.

I am not familiarly with your thermostat so I may be way off base on this. If you are "going up north" for the summer I really would not worry about it, but then from Florida to the boarder is alot of up north. If you are going up north for the winter that's a whole different conversation.

Lets say for the summer, if needed I use my heat pump to take the chill out of the morning air if needed. I have to be careful on setting the temp. as there is only a 5 degree difference between what you want and what the temp is. If you set more than 5 degree the propane furnace comes on until temp is reached. Lets say inside temp reading is 65 and I want it to be 72. I set heat pump to reach 69 then again to 72. Again that's my thermostat maybe not yours. I all so have a separate electric heater I use if needed, so far have not. Because I am a cheap sob I try not to run the propane furnace as it really likes to use propane. I guess to answer one of your questions I will always choose heat pump.

Thanks for that info. I am up in Nashville right now and today at 70° but then Monday it's supposed to be 22° at night so I'm trying to be somewhat proactive before my toes freeze.

Use the gas furnace setting below 40 degrees, use the heat pump above. The heat pumps are incorporated into the A/C units.

I have the MicroAir thermostat on our 2007 Journey. There is a setting to allow the gas furnace to come on automatically when the temp is low outside and the heat pump cannot provide enough heat. Then set for the Cool-Heatpump mode and set the cooling and hetating temperature limits. This allows it to automatically use cooling or heat pump heating based on the temp settings. While in this mode, if the outside temp is below 35-40 F it will automatically start the gas furnace when running. Set the fan to non-automatic while in the furnace mode, otherwise the heat pump fan will also run with the furnace fan, but it just blows cool air.
