My heat is working well but it cannot be lowered on thermostat
1253137
I'm not anywhere close to being an expert but the problem I had was the only time I could get heat to the third zone was if the thermostat for the first or second zone was on and then the heat would never come up to the full temp no matter how high I set it. I talked to a friend who does HVAC and just by what I described he said "sounds like a zone valve" and that they're really easy to replace, so I took a chance and purchased the Taco 555-050RP, found a few videos on YouTube and did it myself and it worked! I wish I would have done it sooner as I had the problem for 2 years but it would be very expensive between parts and labor to have someone come out, diagnose the problem and then fix it.

I can think of a couple of possibilities: 1. The thermostat may be malfunctioning and calling for heat continuously. A thermostat is basically a temperature controlled switch. When it calls for heat it completes a circuit that sends voltage to the heating system (the Taco valve head in my system), and when the room temperature reaches the set point the thermostat opens the circuit and the heat should go off. 2. The water valve for a zone in the house may be stuck open. Check the Taco valve head for the zone in question and make sure the manual bypass lever on the side is not pushed down. If it is, the water valve will be held open and the circulator pump will run continuously. I posted an answer to somebody else's previous question about a system not producing heat. I included a description of how my system works which may help you in understanding how yours works. Good luck.

The thermostat I have purchased recently has a really nice program to set temp differential.Turn the thermostat HEAT/COOL switch to OFF. Press the center button, also labeled as SAVE, for five or ten seconds until it flashes the differential number.The number is adjustable from one to nine. Press the temp up or down buttons to change the differential setting. A setting of one is the tightest range (less than one degree differential). A setting of 2 gives somewhat wider differential, about +or- one degree. Etc.After you have made your selection press the SAVE button and the room temperature will be displayed. Then set back to HEAT/COOL. The thermostat I have purchased recently has a really nice program to set temp differential.Turn the thermostat HEAT/COOL switch to OFF.

I find this is a noticable issue when using the high side of "Low" (the first dot). I need lower heat for my dress pants, but want some steam. What happens is no steam, followed by spurting steam, followed by no steam as the thermostat kicks on then off. The iron's thermostat is too crude to keep it heated at that chosen spot. My assumption is that this shows a swing of at least 20 degrees, and at just the spot water could become steam. It's annoying.

My heater does the same.I had two since the first broke. I think their thermostats just dont work well.

I can think of only two possibilities here: 1. The wiring is not correct (or there is somehow a short across the temperature sensor/relay), or 2. The fan is set to ON instead of AUTO. Wiring is the culprit in a high percentage of this kind of problem, but it is possible that the thermostat's circuit board could be defective.

This is NOT a defect and it IS normal when the "C" terminal of your thermostat is powered from your heating/cooling device. You need to change configuration item number 10 from "ON" to "OFF" (this is clearly described in the manual).

there is a thermostat that goes low, medium, high. What I did was buy a a good quality thermometer, drill a hole in the lid and tighten the thermometer down which works pretty well, however keep in mind you may want to put it in the side a bit lower so you know what the temperature is in the lower rack rather than the top rack closer to the lid

The adjustment for temperature leaves a lot to be desired. You are better off having an electrician install a thermostat on it. On the low settings mine would still turn on in my garage, with the garage door open, when it was 80 degrees outside.

Sounds like you have a bad control board. The temp can be set on both the front face of the unit and with the remote control. Take it back and get a new one!!

I haven't had that problem. My thermostat follows the schedule I've programed. There may be a problem with your unit.

You can use the thermostat on the low setting, but the automatic shutoff and turn on will not work as described in the instruction booklet.

Hi Harold - there must be a defect then. I set mine for 345 and it stops at that - it will fluctuate a few degrees down when in use - but nothing major. I would contact them and have it replaced

It sounds as though the thermostat is not functioning correctly. I would call the vendor from whom you bought the machine...or the nearest dealer.

The heater is not adjustable and if you want it on you have to turn it on. It turns off at 140 degrees.

I am no expert but it sounds like you have a defective TH 106. The on/off feature on these thermostats is triggered by the temperature at the TH 106. I would return it for replacement. Ted

To ensure the temperatures are nearly the same, make sure you place all comparing thermostats in the same exact location. Even testing across the room can make a difference, possibly what you are experiencing.

There is a switch on the side that has low, med, and high settings. As far as being able to hook up a thermostat that is a little out of my area of expertise, but I assume with the proper knowledge you should be able to. I assume mine is wired that way right now. Thermostat calls for heat, boiler comes on, once the boiler reaches a set temp the pump comes on. Once the boiler reaches a high set temp the boiler shuts down but the pump continues until a low set temp is reached. Guesses only.
