Dual heat system, honeywell thermostat, auxiliary heat won't turn on

Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

what wires land where on your tstat?

If the thermostat is wired correctly, and matched to the type of heat you have ie electric, heat pump, boiler, forced air, gas or oil, the heat should run in either Fan ON or AUTO. Maybe you can explain your system a little more in depth...furnace type, M#, & thermostat brand w/ M#.

Are you talking about a pro 5000 Thermostat??? if so then NO it will not work.With this stat you do not have a temperature lock on the heat pump. Say you don't want the heat pump to run below 25 degrees. it won't shut the heat pump. And you don't want the heat pump to run at the same time as the furnace. With the Pro 8000 3 heat and 2 cool thermostat you can lock out the heat pump at 25 degrees outside an turn the furnace on. You will have to install an outdoor thermostat hooked up to the pro 8000 it usually comes with the stat. Honeywell products.

Auxiliary Heat is used to turn the electric heat strips ON, If the heat pump is not working. Or if the heat pump can't bring the space temperature up to Set Temperature it will display Aux Heat ON....... Assuming you have a Heat Pump System with Auxiliary Electric Heat as Back up...... If the tech didn't install a jumper wire from AUX to W on the subase which is in back of the Display on the Thermostat.....you won't get Auxiliary Heat if the Thermostat is set for Auxiliary Heat. Other wise the thermostat will turn the heat pump on first and then the electric heat (Aux Heat) if it needs it to satisfy the set temperature....... Hope this helps

Yes, I believe you are correct concerning the circuit panel.

Regarding your heat pump not keeping up ...depending on what part of the country you live in, heat pumps are not the best thing to heat with. As you probably already know, once it reaches 32 degrees outside, the heat pump stops working and the electric furnace or heat strips come on to supply warm air. Frankly, when that happens, it's like turning on your kitchen toaster and blowing air across it with an electric fan. Doesn't sound to efficient does it. Plus, your electric meter is spinning like crazy and the power company is falling in love with you.

In my area (Virginia) most new home construction is now using what's called a dual fuel system. It's a heat pump, but it has a gas furnace backup for when it reaches 35 degrees outdoors. It's very, very efficient and a very comfortable heat. The gas furnace can run on either Natural Gas or Propane Gas.
In most cases this can be added to an existing heat pump system. The only thing necessary is the Gas Furnace, since you already have a heat pump and all the duct work. Could probably be added for a whole lot less than you''d expect.

The other option is to add a vent-free gas fireplace or vent-free gas logs, if you have an existing solid fuel burning fireplace. They are great for zone heating and/or supplemental heating. Plus, if you have a power outage in the middle of the winter, they'll still work, as they don't require any electricity.

I didn't mean to run own, but I hope all this helps you solve your heating problem.
Please let me know.

Auxiliary heat is electric heat that is put into the air handler on the inside of the house. Its used when your heat pump doesn't provide enough heat, but heat strips are not always used. To see if you have auxiliary heat, look inside and see if you have breakers on the front panel of the air handler or anywhere close. No breakers, no electric heat. Hope this helps!

?? Connect Wires 5.

Labels don't match?

If a wire does not match any terminal on the thermostat,

see next page.

Quick Installation Guide

Alternate Wiring

If a labeled wire does not match any terminal

designation, see diagram below.

Do not use C, C1 or X wire. Do not use B wire if you already

have O wire. Wrap bare end of wire with electrical tape.

This thermostat cannot be used if your old thermostat had

any two of the following wires: R, RC, RH, 4 and V.

Place a jumper (piece of wire) between Y and W if you have

a heat pump without auxiliary/back-up heat.

Set jumper JP1, on the back of the thermostat, if you

have connected a wire to the G terminal.

Incorrect jumper setting: An incorrect setting is

noticeable in a gas or oil heating system. When heating

starts, you will initially feel cold air coming out of the vents

as the fan is running before the furnace has enough time

to heat up the air.

?? Set Heating Fan Control 6.

HG Leave the jumper in this factory-set

position if you have a gas or oil furnace.

HE Place the jumper to this position if you

have an electric furnace.

Set jumper JP2, on the back of the thermostat, if you

have a heat pump.

Incorrect jumper setting: The heat pump operation

will be reversed, i.e., it will cool in Heat mode and will

heat in Cool mode.

?? Set Heat Pump Reversing Valve 7.

O Leave the jumper in this factory-set

position if you have connected O wire to

the O/B terminal.

B Place the jumper to this position if you

have connected B wire to the O/B terminal.

1) Install 2 AAA

batteries on the

back of the

thermostat.

2) Align the two

brackets on the

top of the

thermostat with

the corresponding

slots on the top of

the wallplate.

3) Push the

thermostat

against the

wallplate.

4) Tighten the screw

at the bottom of

the thermostat.

5) Turn power back

on at the heating/

cooling system.

Whats' so hard is the Honeywell thermostat has a built in 1@ differential. It is not adjustable.
You might ask your installer about a time delay relay installed in the furnace to break the thermostat heat wire (usually white wire).
Most time delay relays are 90 seconds. But that might be enough to reduce the furnace cycling.

Did they check the sensor in the plenum. You are suppose to have bonnet sensor to switch from heat heat pump to gas whaen it is to cold for the heat pump. The bonnet sensor may be to bad. The unit is cycling ever five minutes because it may have five minute time delay.
