I recently bought a home that was built in 1955, that has 3 zone hot water baseboard heat. Each zone had its own thermostat. Two had been updated to 24 volts, and one still had straight line voltage (120 volts). I wanted to put in programmable thermostats, and this Honeywell model was the only one that could handle both. It makes programming them easy since they are all the same. Installation involves just hooking up a few wires, and your ready to go! The only reason I give these 4 stars instead of 5 is because you can only program two different temperature settings a day. One tempurature for when you wake and return home from work, and one for when you are away during the day and your in bed. I don't know why it wouldn't have the function of letting you set 4 different temperatures, one for each of these times, when even the cheapest most simple models let you do this, but oh well. You just get used to it.[...] Thanks Pex, and I will be back for more!

works well, not for bedrooms!

Thermostat works well and was fairly easy to set up. I cannot recommend installing in a bedroom though, the relay inside the thermostat is quite loud.

Perfect Thermostat for Baseboard Heaters

By Big E

from Chicago, IL

Verified Reviewer

Comments about Multi-Application 7-Day Programmable Electronic Thermostat:

I replaced some old baseboard heaters (individual thermostats on each unit) and wanted a wall mounted programmable thermostat that would control 2 heaters. This Honeywell unit fit perfectly. It's power is supplied by its AA batteries so no power is needed from the baseboard heaters. I chose to use low voltage wiring to connect to the heaters, so the small wires could be buried easily without tearing up walls. The only negative is that programming isn't as flexible as other thermostats. There is only one daytime temperature and one nighttime temperature to choose from when programming the unit for automatic operation.

Easy and Uncomplicated Programable

Comments about Multi-Application 7-Day Programmable Electronic Thermostat:

Heat only thermostat. Yea you can get a cheaper Heating/Cooling Unit at the local big box but, consider if you only have a heating system all the extra buttons, knobs and settings that you would not be using that would make the unit complicated to use. Even your grandmother can use this one.

    Q:

    I was told to hook this up - to connect to terminals 1 and 3, but the wires coming from the 24volt valve uses three wires -- any suggestions

      A:

      This thermostat is a very simple battery powered relay that works on time and temperature.
      It is a simple on/off single pole -single throw switch.
      I am not sure what the function of the 3rd wire is on the 24 volt valve you reference is used for.
      You must identify what 2 wires turn your fuction on/off and connect it to this thermostat relay.
      I used this to replace an older 2 wire 120v line voltage manual thermostat.
      This may not be the thermostat that you need for your application.

      A:

      If this is the thermostat I have, and I believe it is, it is only suitable for 120 or 240 volts feeding an electric heater or, as in my case, the 120 volt power to a gas-fired unit heater. The 24-volt supply for the gas valve comes from a transformer on the heater unit that feeds a control unit for the gas-fired heater. If you need a thermostat for 24-volts you may have the wrong item.

      Answered on 4/25/2012 by Another PexSupply Customer
    • VERIFIED BUYER

      A:

      Sounds like your 24volt valve needs to be powered open and powered closed
      if it has 3 wires. You will need to use terminals 1-2-3 in this case.
      Wire your common to 3 (24v) Valve open to 1 (N/O) and Valve closed to 2
      (N/C). Hopefully it is noted on the valve which wire is which or its
      marked on your original thermostat.

    • VERIFIED BUYER

      A:

      No expert but, 2 of your 3 wires should activate your heater. The third may be a
      neutral( not necessary for this thermostat) or a for A/C unit. Test your wires
      to see which 2 activate the heat and connect them to terminals 1 and 3 on the
      T8100.

      I understand it is quite good for this type of application (I'm assuming it

      the set point.

      A:

      We have used these on several installations with no complaints. They work very well as a heating only zone thermostat. One reason we like them is their pump exercise option which is good for systems that sit idle during the summer to prevent pump seizures. The only drawback I have observed with them is that the relay switches with a noticeable "click" when it turns on or off.  I installed one for a relative and noticed in the middle of the night that when it cycled, it was louder than I would prefer sleeping in the adjacent bedroom. Apart from that, zero problems.
       
      Using it with valves should be fine, depending on how you are planning on wiring it. If you are using a zone valve controller (like a Taco ZVC-503 or 504, etc.) it just connects to the thermostat "T-T" inputs and your valves get connected to that zone's valve output. If you are wiring the t'stat directly to the valve, then make sure keep the wiring for the valve end switches straight so you don't short the transformer when a valve opens.
       
      Also, just FYI, if you are using a zoning controller of some sort, you can use pretty much any heating capable t'stat you like. The valves don't care and the boiler won't either. If you are not using a controller, then you have to be more aware of what is getting connected to what and that may narrow your choices.
       
      Good luck!
