Completely different set up from what I have. You also might be in the wrong forum. This is for heat pumps which provide both Heating and Cooling, not straight AC units. Most heat pumps will typically have an orange wire running directly to the thermostat. Good luck!
You need to reset your wyze and re add it. When it walks you through setup, at the very end when it asks you what W1 does, you need to tell it that it is a radiator.
Thanks. Ill test it.
Yes, I have cast iron radiators for heat. There are circulator pumps on the boiler that circulate the hot water to the radiators. What happens for me, the A/C fan goes on, but the heat doesnât.
As long as you have told it that you have the following wires, and that your W1 wire is a gas fired radiator, it should work as you expect it to:
Rc
Rh
G
Y1
W1
C
What happens to that temperature reading if you just turn the fan on? Is the air temperature stratified in the room, and the fan stirs up the cooler air near the floor or outside wall?
Any news on the aux indication? Some control over it or something? Would be nice to know when itâs running in aux mode!
Not sure if my answer is even necessary at this point. But the quick answer is A BIG NO. Thermostat doesnât display if itâs using your AUXILIARY source or just regular heating. Nor does the app displays that information.
However, if your wiring is correct, you can turn on EMERGENCY heat from the app. Thatâs one big reason Iâm testing Amazonâs thermostats trying to make the move.
Hope that helps.
Update: Did some more digging with auxiliary heating and found out auxiliary heating is not used at all by the thermostat. Look at my screenshot- you can see the temperature needs to go to 73 from 69 which is a 4° difference and usually anything above 3°, the auxiliary heat should come on and it should not take 35 minutes to reach that temperature. My old non-smart thermostats were capable of using auxiliary heat but not Wyze.
How do you turn emergency on from the app?
Let us know how the Amazon thermostats are. Iâm about to make the switch to those too.
Yes please! need control over aux heat. it is on way to often. If amazon does I am changing over.

- Go to the Thermostatâs dashboard
- Tap the cogwheel on the top right corner
- Scroll down and tap ADVANCED
- Toggle EMERGENCY HEAT on
- Tap ENABLE on the popup
If you go back to the dashboard again, you can see the dashboardâs color is somewhat different from red.
Thatâs it.
I will.
Heat pump I- have no emergency selection⌠It must be in the wiring. It works perfectly just no option to select aux or emergency. Maybe Amazon will. Wyse-- how hard is this to add. all my Honeywells had this option!
Iâve done some initial testing on Amazon Thermostats. Works better than Wyze thermostats. Even installation is easier than Wyze. It asks you questions to determine what kind of an HVAC system you have. There was no issue at all for the thermostat to know that mine is a heat pump with electric furnace as an auxiliary source.
The main reason I was pissed off at Wyze for not utilizing my auxiliary source has been taken care of by Amazon nicely, Anytime I want to raise the temp by 3 degrees or more, the aux heating starts automatically and for that, the heating time has been significantly reduced. Hope that saves me money in the long run.
Here is the list of things I like about the Amazon thermostat:
- Easy installation process in the app, you know what you are doing, not guessing
- The thermostat looks way better on the wall, though this is subjective
- Uses the Aux heating right of the box, no fiddling needed
- Consistently keeps the temp within the set range
- Easy-to-understand scheduling in the app, I donât like hunches
Things I wish Amazon thermostats had:
- Alexa app for thermostats could have been much better, you need to tap many times to get to the thermostat part of the app. No quick way to get there
- Widget support just for the thermostats on your home screen
- Google home support
- Raising/lowering the temp by a few degrees on the thermostat. Wyze has this option. My upstairs thermostat is in a place where there are no direct vents. So during the night, the bedrooms get hotter than what the thermostat displays by 3/4 degrees when the doors are closed.
- You can use hunch for only one thermostat, thatâs a bummer for those who want to use hunches. I personally donât use hunches.

Please see my other comment on Amazon thermostat down below. Hope that helps.
I have a heat pump that has a variable speed fan. My emergency heat comes from propane. I can hear the burner ignite when it kicks on, but it seems it only kicks on when I manually turn on Emergency Heat in the Advanced section of the Wyze App. It is supposed to kick on whenever the outside temperature drops below 40 degrees F. When I run the heater in the System Test mode, the heater does not stay on long enough in any of the 3 heater stages for me to tell whether I am getting any heat. The emergency heat never comes on. The outside temperature has been in the mid 20âs the last couple of days here, and as far as I can tell, the propane heat has never kicked in, and the heat pump has had a hard time keeping the house warm. I can manually turn on Emergency heat, but thatâs what the thermostat should be doing automatically. It seems to me that there should be an outside temperature that automatically triggers emergency heat, like there was with my old thermostat. Iâm not real happy and am thinking of going back to my old thermostat or switching to another brand where i donât feel like Iâm a Guinea Pig trying out a system that hasnât been well tested and lacks in documentation.
My choices seem different than yours, Prasen. I can toggle the Emergency Heat on which starts my propane heat, but after that, there is no popup that says enable. When I go back to the dashboard, the set temperature no longer appears and it tells me I am running on emergency heat. It will run like this until I manually toggle off the Emergency Heat switch.
Yeah, I agree, that should be done automatically. I donât have a Wyze thermostat here yet, nor do I have a heat pump, so I canât say whether or not it was designed for heat pumps. It shouldnât be tough for them to write a proper heat pump sequence, though.
For an air source heat pump, as the outside air temperature goes down, the heat pump operates less and less efficiently. At some point, it will still produce heat, but it will be at the same cost to run as electric heat. There is an outside air temperature, below which, the auxiliary heat, whatever its fuel, is equal to or more cost effective to run than the heat pump reverse cycle. At that setting, the heating control should switch over to the auxiliary heat source. Iâm surprised that the heat pump itself doesnât have this capability, because it is not always run from a smart thermostat. It should decide for itself where to steer a call for heat. That is not too hard to rig up yourself with an outdoor air bulb-type thermostat if the heat pump doesnât already have it.
Just a pedantic quibble, auxiliary heat and emergency heat should not be interchangeable words. They have completely different meanings and functionality.
A water source heat pump would require a different sequence altogether.

Thanks for the reply. Before I purchased the Wyze thermostat, I made sure it was compatible with a heat pump system with propane for auxiliary heat. My old thermostat used 10 wires, and the installation app for the Wyze thermostat gave good guidance on how to connect them. My old Honeywell thermostat used a thermocouple to determine outside temperature and switch on the auxiliary heat below 40 degrees. The Wyze thermostat presumably determines the outside temperature by consulting the internet.
I am using the terms auxiliary or emergency heat interchangeably. I am referring to the backup heat source, which is in my case, propane. My heat pump works fine for temperatures above 40 degrees, but below 40 degrees, it should switch over to propane. The only way I can get the propane heat to come on is by switching to Emergency Heat in the App. The Wyze thermostat seems to control everything else correctly including the variable speed blower.
Thanks again for the reply.
