Is this a fan coil/4 pipe system?

I'd replace the fuse holder to accept a standard 3A blade fuse.

Might have a limit switch tripped, fuse blown, or other issue in the furnace.

Why no more details on the TH8321WF1001?
It's the thermostat I'm currently running at my own house.

Very odd the stat shows the temp going up when the equipment isn't even running.

Honeywell Cycles Per Hour/Temp Swing setting. Does anybody understand how it really works?

I know the setting can be changed from 1 to 9 CPH, and it does affect cycle time. It does NOT equal the...

Make sure the wire hole behind the thermostat is plugged up.

You will need to use a thermostat with a MECHANICAL relay to control the fireplace. Some thermotats have them internal, some you need to wire external. The thermostats that click when the heat comes...

You should be able to do this w/o relays. Each zone should have a "hot" terminal that hooks to 24v, and a W for the heat call. There should be a C terminal on the board to get common.

Were wind speeds similiar?

With very cold (under 10f) temps the delivered COP may not be very good, especially if ductwork is in unconditioned space. You must also account for defrost cycles.

That's what i want to know. Most HVAC on/off cycles are longer than 15 minutes.

The thermostat has a manual fan auto/on switch (most do) the Y&G are connected while the stat is in the "rest state". If the thermostat uses a digital fan auto/on switch Y&G are NOT connected in the...

+1 for staying with the Honeywell. Installing the Nest will just cause headaches.

Looks like a DF control board to me.

Should be able to, doesn't look like a MV system.

Does your system have a DF kit installed? Is there a outdoor mechanical thermostat that switches from HP to LP?
A quality DF thermostat will allow you to select run time of heat pump before...

Nest is a poor choice for those with heat pumps. Staging doesn't work correctly. It's a known issue on Nest.
