Honeywell rth6300b won't turn off

I always use the manual settings to turn on and off the heat. I have baseboard hot water heat. About three weeks ago I turned up the heat before I went to sleep (i put the heat on for usually 15 minutes) then turned the stat down. the heat never turned off. Had to shut off furnace. Changed battery then worked fine. did the same thing today no such luck. Had to shut furnace off tonight , will be 25 degrees any help would be nice.

thanks
jb

I have a hot water system that uses baseboard heaters with two thermostats. the pump is activated through a Honeywell R845A. Is the R845A the problem?


Using that thermostat on a boiler system requires a relay to be installed. like the Taco sr-501 or an Argo AR-822

Why is my honeywell 8320r1003 short cycling for hot water heat.I have heat set at 65 degress.cycling 2min,3min,the most is 8min.


Hi Bill, after closing your thermostat, is this correct the situation?
And how far is your thermostat from your baseboard heater, if the baseboard is underneath the stat, you should move the stat elsewhere. Hope this help you find the problem.

Honeywell thermostat


The wiring is correct but you have a programmable thermostat that needs to have a program to operate. The manual for this particular stat is straight forward and uncomplicated. Enter the times and functions with the right button and up/down arrows then press "DONE" (Left Button) to get it started. Hope this helped. Roger

Replacing a Honeywell T822l1000 thermostat.


The W terminal is used for heating and goes to a small electric valve in the water line to your baseboard. The Y terminal is for a cooling system. The T822 is wired wrong and is not working. The wiring between R and W is corect for a heating only application. The R terminal is the power source.

Hot water not going, wanting to know how to turn it back on?


You have a real good description of your thermostat--
I wonder why you suspect the thermostat to be causing your 'No Hot Water' problem?

First of all, I have to be sure I understand your real problem--
When you say you want to 'turn the Hot Water back on', (It is 'Not going')
Do you mean you want a boiler (maybe in the basement?) -- or maybe a zone valve in a Hot Water, Baseboard heating system-- to be heating your house/ room/ apartment?

I would suppose, if you have the thermostat set higher than the room temperature, that it should be giving a 'call' to the boiler (or Baseboard Hot Water Heater..) to ignite a fire, and heat the waer, and then heat your room, or house.

So-- Could the problem be in the Device heating the Hot Water?

Please tell us more about your heating system-- what type of fuel, -- What happens when you lower the Thermostat, and then raise it-- What used to happen, and what does NOT now happen, etc.

Tell us more clues-- maybe we can help remotely like this-

I have a new Honeywell Round Non-Programmable Heat Only thermostat MFG # T8775A1009. I turned it down to 50 degrees. The room temp. is reading 70 degrees and heat is coming out of my baseboards. Why is...


Make sure the switches on the back of the thermostat is set for hot water heat. If you have more then 1 zone you may a stuck zone valve or a short in the wiring somewhere keeping the boiler on.

Have hot water but no radiators. Checked pilot


sounds like your circulating pump is bad or electronic zone valves

One zone not working; another is partly working


i would check my water pressure on boiler sounds like lack of pressure or air in system they can be related. if you have bleeder on baseboard try to bleed.

Replace three wire thermostat with four wire thermostat


From the two red and two black wires (and the specs in the pdf), your new thermostat sounds like it's designed to directly control the line voltage (120 or 240) to the heater. That's the usual way baseboard heaters are controlled.

Could your wires be red, black, and (old, yellowed) white, the standard colors in a 3-wire power cable? Just the red and black should be enough to control a 120-volt heater so I don't understand what the white would have been used for. If it were my heater I'd take off the cover(s) -- with the power off, of course -- and find out what those wires actually connect to.

Honeywell ST6400C programmer doesn't switch off


Since you have three on/off timing modes could there be an overlap in the times?
The wires in the unit might be crossed. (don't always assume the contractor who wired maintained the correct colors , I have a friend who blew out a heating pipe because when a replacement motor valve was installed it was never wired right and the plumber assumed the colors were correct so no overtemp shutoff created steam in PVC pipes, OPPS)
There fore maybe one is still coming on. Do you have more than one heating zone? IF so see below

I guess the main question is why manually turn it off? why not use the program.

I will assume your heat is know as forced hot water heating. My house is multizoned however when the zone calling for heat turns off (zone valve closes) I installed a bypass valve in the lowest zone in the house, and reduced the circulator low shut off temp to 130 F which means even though the heat isn't on my circulator will continue to run dumping this excess heat in the lowest part of house to rise through house. (the spring loaded water valve allows the heated water to flow into this zone )We do have two thermistats. And even though the lowest one is not calling for heat the radiators are hot when the excess is dumped into this zone. So investigate and see if your system might be similar. (multizone).

Investigate your wiring, reprogram, replace any battery backup.
