Want to install NEST in my HVAC condo..?
Hello everyone,
As the title suggests, I want to replace the old Honeywell thermostat in my condo here in Ottawa, Canada.
My condo has HVAC
I've attached pictures of my set up. I'm wondering how hard this will be to do (DIY). There are only 3 options for fan speeds on my current thermostat (Auto, Smart, and On) which suggests it can only currently be programmed for one speed. However, are our heat pump (furnace) there is a switch, for lo/high fan speed.
Our current thermostat is 24v so I assume that the NEST would work perfectly...
Can someone please offer advice? Much appreciated!

Since you have separate Rh and Rc you would need to go with the 3rd gen Nest as the E version only has a single R. When setting up you probably need to tell the Nest that you need to turn the fan on with heat.
Since the speed switch is on the unit Nest has no ability to control it.

Gas furnaces usually control fan operation in heat mode.
Electric heat and forced air hot water air handlers usually do not control fan operation in heat mode.
Most condos don’t have gas furnaces.
Unless you have a gas furnace it is usually recommended to configure the thermostat to energize the fan in heat mode.
