Wiring a Honeywell VisionPRO TH8320U1008 Thermostat

I have a Florida Geo heat pump 2 stage with no aux.heat. It is controlled by a Zone Perfect Two-Zone Unit hooked up to two Totaline P274-0300-C thermostats. Everything works great this way.
I was talked into buying a Honeywell VisionPRO TH8320U1008 to replace the Totaline on zone-1. They said the Honeywell can be wired for any system. Anyway, I can't take it back and I can't get it to work properly.
The Totaline is wired as follows BLK-0/W2/B RED-R BRN-C BLU-Y/Y2 YL-Y1 GRN-G WHT-W/W1. A total of 7 wires hooked up.
The Honeywell only calls for 6 wires to be hooked up in the 2H/2C Heat Pump mode with [no auxiliary heat] I hooked the wires up as follows BLU-Y2 RED-R/RC Note, R+RC are jumpered. BLK-0/B YL-Y GRN-G BRN-C. I stored the WHT wire. Wired this way the heat pump would work, but would not control the reversing valve when when calling for heat.
The Florida Geo heat pump has the the reversing valve energized in the cooling mode.
Any help with this problem will be greatly appreciated.

My Hunter model 44132 thermostat is flashing AUX. Why and how do i correct this problem?

When your thermostat displays "Aux Heat", this is simply a reminder that the second stage of heat is now ON. This occurs whenever the room temperature drops more than 2 degrees and activates the Second Stage of Heating (Aux Heat). This is a normal operation of your 2 Stage Heat Pump thermostat and it will not affect your thermostats performance at all.

How to I control this ridiculous thermostat (Totaline P310-0210) Just moved into this house and no manual, if I press buttons it says stage 1 or stage 2, I/m freezing...someone help!!

Hello Stephanie Sakata,

I found 2 (two) "TOTALINE" manuals...

These little beauties all work pretty much the same...

Put the slide switch in HEAT MODE...

Push the "HOLD".. (which keeps any/all
clocks/gadgets and BACK-SETS off)...

and ADJUST THE TEMPERATURE where you want it...

Read these manuals (

I am installing a totaline progammable thermostat, the old one is a rheem, i hooked the b wire to the b terminal the r wire to the r terminal the g to the g terminal and the y to the y terminal the e l and...

First off, make sure that the wires you are connecting at the thermostat match the circuit board of the unit. It is good practice, but not always followed to do a "1 for 1". To answer your question, W2 is simply when there is 2-stages of heating. If your furnace does not have 2-stage heating, then leave it empty on the t-stat. "C" is common. Common is neutral, so it should have continuity to the ground or L2. If your old stat did not utilize this, I wouldn't worry about it, unless the new stat is a touchscreen and constantly lit stat. Just keep this in mind. W-warm (heat), Y-cooling, G-fan, R-hot (main 24v power from furnace to thermostat), C-common (not always required), AUX (auxillary, if there wasn't one used on your last furnace, I wouldn't worry about it.). X may have been a common, or a dead terminal.
Bottom line, if you open your furnace to see the circuit board and where the thermostat wire connects, and match above, you should be just fine. Make sure you turn power off prior to opening the furnace, and when landing the wires on the stat. You could inadvertently blow the 24v transformer.

I have a Rheem A/C Heat Pump split with gas backup. The gas unit is mounted in the air flow directly before the A/C HP coil. Should the gas unit be wired as stage two heat, or is it OK to wire it as just...

Stage 2 is okay as long as there is a fossil-fuel kit accessory wired in the field control wiring. EM heat would only allow gas furnace operation if the thermostat is set for EMER HT mode.......this is not ideal and not recommended. Dual-Fuel applications require a fossil fuel kit.
I'm including a link with information on one type of fossil fuel kit. It explains how it works. If you have limited HVAC service knowledge and/or experience, I recommend having an experienced service technician check your system operation in all modes to ensure proper operation for longer system life at peak operating efficiency.

Thermostat runs aux. heat all the time

sounds like a wiring issue to me

either there are wires going to the wrong terminals on the t.stat, or there is a physical problem with 1 or more wires somewhere

it is also possible that the new thermostat will not correctly control the unit that you are trying to operate. Unfortunately, just because it has all the right color terminals, does not always mean that they all operate the same.

Good Luck!

What is the difference between stage two and aux heat?

The furnace shoud be wired to W1 amd EM Heat. If your heater is a two stage furnace then hook the thermostat W1 to stage 1 amd W2 to stage 2. Most new 2 stage heaters will control stage 2 with the control board.

Honeywell Thermostat

Make sure G from indoor unit goes to G on thermostat for fan continous fan, if that doesn't work and you have 24 volts to R and C then the t'stat is bad.
For 2nd stage heat or aux.heat, on the indoor unit you need to make sure the wire W2 from the indoor unit goes to W2 on t'stat.
You don't need any wires from W1on the indoor unit to W1 at the t'stat because with a York heat pump Y1 is the contactor which turns the compressor on and you will get 1st stage heat, and for cooling the t'stat will also bring on O which is the (reversing valve) or cooling changeover relay for the cooling mode.
C = common usually black wire
R = hot usually red wire
Y or Y1 = contactor
W1 = 1st stage heat not needed for heat pump
W2 = Aux. heat indoor heat
G = fan
O = Cooling changeover relay
B = Heating changeover relay
L = System monitor
E = Emergency heat relay
