Used to regulate electric heat in a finished basement. Had three of them and one got broken during carpet installation . It is accurate and easy to install, box has everything necessary. It was an easy swap. Glad I found it online, could not find it in a local store.

Beware

Comments about T4398 Electric Heat Thermostat, w/ Thermometer & Pos Off Switch:

No where in PEX's specifications did it indicate that this was a double pole unit so I had to send it back and order the single pole thermostat that does not have a positive off switch which was the feature that I really wanted. Even the PEX's representative could not find any reference to this unit being a double pole.
The single pole was a real struggle. It was not even close on the temperature setting being easily 5 and sometimes 10 degrees off. The instructions state that the unit could be adjusted for elevation which means that you can adjust the temperature settings by turning an inner ring while holding on to the control knob. Wow, maybe if you have a pet gorilla. I am a rock climber with a very very strong grip and I could not get the ring to turn on the "nubbins". I had to take a sharp knife point and pry down the notches in order to rotate the ring. I turned the ring to the maximum allowable and even with that it was still several degrees off at an elevation of 3200'. There is a warning on the unit that states one should NOT pull the knob off the unit as this could damage the controls. I figured that I had nothing to lose at this point so I did pull the knob off and pushed it back on to the desired location. Now my thermostats are set to the correct temperature settings and work wonderfully well but it required a really unsophisticated and unnecessary method that Honeywell should be embarrassed about.

So far so good

Comments about T4398 Electric Heat Thermostat, w/ Thermometer & Pos Off Switch:

This is the 3rd line-voltage thermostat I have used for my three baseboard heaters in my basement rec room. All three heaters total 4000 watts. The first one burnt up so it may have not been sized appropriately. The 2nd one became stuck in the on position and would not regulate at all. This Honeywell seems to function very good. The calibration for temperature setting is off approx 5 degrees as compared to a glass bulb type thermometer positioned at the thermostat location. Not a big deal and I'm just glad that it regulates so I don't have to keep turning it off an on manually.

Honeywell T4398 Electric Thermostat

Comments about T4398 Electric Heat Thermostat, w/ Thermometer & Pos Off Switch:

Replaced 7, 13-yr old baseboard thermostats that were difficult to adjust temp & to closely hold a set temp.
Well built thermostat w/easy accurate adjustment & holds set temps to within 1 or 2 degrees.
Fastening the cover onto to the base thermostat was tricky because of small allen screws. Also, the thermostat would be more user friendly if a digital temp room readout was built in instead of the small spring style temp imdicator.
Looked long & hard to find the best 'mordern' thermostat. This was it & like them. Could not use digital-type thermostats becauseif power goes out, they automatically reset to something like 70 degrees. As we are gone for a month or so during the winter plus we have dual-fuel electric service, digital thermostats are not an option for us.

Took me awhile to find a thermostat that would work with my old school radiant ceiling heat! This one is great. Very efficient & true to temperature. Easy to install.

This product does what it says!

Comments about T4398 Electric Heat Thermostat, w/ Thermometer & Pos Off Switch:

I purchased eleven of these for our cottages here in Northern Wisconsin. The old bi metal thermostats we had kept the heat on all the time, and our guests always had the windows open. Since I put these in our guests comment on how even the tempuature is, and how they have the thermostats set lower than normal, and can control the heat. This thermostat was very easy to install, and the ordering process through PexSupply was very simple. I received the thermostats in about four days. This product does what it says,I will definitely have a cost savings this winter with this product. One negative, the locking cover parts must be installed before instalation, this feature could be improved on by Honeywell.

Comments about T4398 Electric Heat Thermostat, w/ Thermometer & Pos Off Switch:

Only reason I didn't give it a five star rating is because I haven't had it long enough to really judge it, however after 1 year of use there is absolutely no reason to think it will not last for many more years.

    will this thermostat work as a single pole line voltage unit??

      A:

      This thermostat works with DPST (double post line voltage) with positive off, as well as with SPST (single post line voltage) applications. It works on 22A at 120/208/240 VAC (non-inductive resistive rating).

    • CUSTOMER CARE

      A:

      In order to determine whether or not a thermostat will work for a ceiling heat application, we need to know the wattage, amp draw, and voltage of the system.
