Can anyone describe the wiring set-up for this unit?. I am replacing a four wire dial thermostat from 1985. Electric baseboard heat.

Its easy. 240 volts in (two wires) and two wires out (to the baseboard heater).

Sorry for the delay. I don't know anything about this. My husband is out of town on business and this is his thermostat. He'll be back this weekend and will check into your question.

Unit has four wires. Red and Black load wires are clearly labeled, as are black L1 and red L2. Connection diagram is included in the instructions booklet.

I ordered this product. My heat tape came with wires that on one end I clipped into the conducting part of the heat tape and the other end had a plug-in that plugged directly into the thermostat I was using. It was very easy to install. There are also multiple videos out on YouTube that give a good overview of getting the heat tape wired up. I suggest looking there as well. Good luck. I love mine - it has worked flawlessly for months now.

Ground!Be sure that your unit doesn't have a low voltage circuit that's available. Perhaps you'll have to run additional wire to the thermostat from the unit, but the extra unit may not be necessary, I was happily using it as directed until discovering that voltage was already on my furnace.Pays to check.Dee

I would recommend checking the amp draw of the elements, when the thermostats or NOT CALLING (on). If there is any draw at this time, then the element needs to be replaced.

The thermostat is just a dial...high to low. I just set it to the lowest setting. According to the specs, the lowest setting has the heater coming on at 35 degrees.

It's been a while since I installed, but I think if you don't install the common wire you will have a battery operated thermostat. If you have the complete 24 volt circuit, (Common installed), batteries will be the backup, in case of AC power failure.

My previous set up was 3 wires. 2 hot and a ground. I did a few searches and was told that this unit did not need the ground wire so I left it disconnected as there is no place to connect it. The unit has been working fine for 8+ months now.

Honestly I had the same problem. the wires aren't lined up right. you have them matched incorrectly. hard to know without a diagram. I had someone help me with a lead tester. that helped to at least identify the hot wires. then you just match them up to the right ones on the unit.

Here ya go. Hook up the red & green wires for heat. I'm assuming you don't have A/C hooked to your thermostat.http://www.ehow.com/how_5552276_wire-honeywell-thermostat.html

with the th115-a-120s thermostats set it and forget it. i have never run one in my home witout the 115. 4 units /th115 code where i live. i have 10 units. i think they are cheaper to run than go thermmo. 1000sq ft. home for about 8 yrs.

There are multiple wiring configurations included in the unit's instruction manual, I would suggest searching the web for an electronic version and downloading it to see if it includes everything you need, or contacting Honeywell directly.

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.

Sorry, mine is just a replacement furnace thermostat. I know nothing about it.

I'm sorry but I decided to change my whole system to a ductless heat pump (best thing I've done to this house). I actually never used the thermostat, ended up in my good stuff junk pile. Wish I could help more.

If you want to use the automatic setting, you'll need to run wires for the outside temperature sensor. Most of the rest of the wires should be pretty similar though.

I experienced a power surge in my home which fried this thermostat so I just ordered the same model number thinking I could just plug it in and replace it. Come to find out it is a contractor thermostat and there is programming of some sort that has to be done so I ended up calling an HVAC person to get it working. Good luck.
