Will this thermostat replace one made for a system with aux heat/emergency heat? Should have 7 wires I believe. Needs to work w/heat pump.

I use this on my geo thermal unit system with aux heat/emergency heat. I had to have the geo guy come out, but that was because it had to be programed. The instructions that come with it showed how to do this, but I guess I missed a step. Has been working fine for about 2 years now.

Yes you will need the wire for the heat. I did my install myself and turned into a pain. you can use the existing wire that can control the heat

I suggest you download the manual and wire it per the instructions in the manual. Important! The Wi-Fi thermostat requires a C wire to operate. The C, or common, wirebrings 24 VAC power to the thermostat. Many older mechanical or battery operatedthermostats do not require a C wire. If you don't have a C wire, try:* Looking for an unused wire that is pushed into the wall. Connect that wire to C andcheck that it is connected to the 24 VAC common at your heating/cooling system.Note: Not all heating/cooling systems label the 24 VAC common C. Check your systemmanual or contact the manufacturer to find out which terminal is the 24 VAC common.Or, call a qualify service company and have them solve the problem.

This Thermostat takes 4 wires. Compare the wiring design of your current thermostat with the Honeywell. I had to run the 4th wire for my system which was the C wire.

Depends on your system. www.white-rodgers.com has a search feature. search for 1f56n-444. you will find a basic heat/cool wiring diagram and other diagrams, electric heat, heat pump, etc., if needed.

Not sure about your heating system, but mine has two wires only. I connected them to R and W with no issues.

It needs two wires for 24volts. Just installed one at my home. It's a great thermostat and install is not difficult, just give yourself an afternoon to make it look nice. Good luck

Yes. It should work just fine. This kit comes with the wire harness wired to two heaters and a thermostat. It took 5 min to install..

Hi Patrick no, the unit is more for replacement i used my existing wiring and air tube. hope this helps ?

I believe so...I've had this same model on 3 different furnace systems, none had A/C but this handles that too. It's a pretty universal thermostat for many different applications...With Seriel Numbers that close, I wouldn't worry...It's a 3 wire system, plain and simple...k.j.

You need Ac Delco water pump inlet 15-11057. Should come with thermostat and bolts do not need replacing. Maybe some blue loctite on threads of bolts good idea.

No Eric - you need to but a plug in thermostat be careful of your electrical system - I burned out the circuit using this heater and had to re wire that room and put it on it's own breaker - my house is 100 yrs old and still had some hidden nob & tube wiring which I feel contributed to the problem - ever since the new wire is in no problems

Yes. I have it configured with heat pump, along with emergency elec heat - to make sure you have the advanced model.

I bought this for a customer so I can't remember what model it was. As long as it is a 12v heat/cool thermostat that you need it should work fine.

No, not a problem at all. The thermostat has inputs (places for wires) for heat, fan, AC, heat pumps and sensors. See the install manual here: http://www.venstar.com/Support/Manuals/T5800ManualRev5b.pdf

My heater used four wires. But the directions gave several different ways to wire the thermostat. You should be able to go on line with Honeywell an get the instructions. So far it is a great thermostat, lay in bed or on the way home and can turn the heater on or off with my iPhone. Also can talk to it to get it to turn up or down the heat.
