Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater

1 Answer

Thermostat temperatures not reaching preset Energy Star settings

I've just installed my 5-2 day Programmable Thermostat (RTH2310B). I have hot water zone heating (heated by natural gas). I have not programmed any other heating pattern, preferring it to run on the preset 4 Energy Star settings throughout the day. I've checked the thermostat and confirmed the sequence is preset the same as the manual: #1 Wake 6 am 70 F, #2 Leave 8 am 62 F, #3 Return 6 pm 70 F, #4 Sleep 10 pm 62 F. However, the temperature on the thermostat shows a consistent 70-72 degrees at all times of the day. The temperature never goes down to the scheduled 62 degrees at Leave or Sleep time (i.e. I checked it at 1 a.m. and it was still at 70 instead of knocking down to 62 as per the program) Any idea why it's not following the preset program?

Well with a boiler system like you have it will cost you more money to heat your house that way than if you leave it like it is. With a boiler system it takes a lot longer to heat an area than with a furnace. The best thing you can do is find a happy medium and leave it there at all times. If you read the paper work on your new thermostats they have a set procedure which tells the thermostat if you have forced air or boiler system. Do you have baseboard or in-floor heat how many zones do you have.

I just installed a Honeywell 5.2 Day RTH2310B Programmable thermostat and I had to deal with the same situation: 2 wires, one white one black. After reading the edvice in one of the blog, the solution that worked for me was: BLACK ON Rc terminal and WHITE on W terminal. My furnace is running fine now. Hope it helps.

Lux Thermostat 500


The Lux 500 Thermostat is an affordable programmable thermostat that gives you a very easy way to customize your heating and cooling temperatures to your schedule. The programming of this thermostat is easily the simplest that I have found in a programmable t-stat.

The Lux 500 series thermostats are a great economical way to reduce energy and utility expenses by raising or lowering your temperature settings a the times you set. The installation is so easy that most any DIY’er can install this thermostat. It has an easy to read display and the rotary dial makes the programming very user friendly.

A few of the other great features of this unit are, a keyboard lockout, and an air filter reminder.

This thermostat can be used on any 24v AC or 750mV single stage conventional heating/cooling system. Single stage heat pumps without auxiliary heat will also work with this thermostat.

Here is a summary of the features of this thermostat

Trying to hook up a RTH2310B thermostat to a wood pellet stove with only two wires.. How do I know where to connect them too?


Hey Brad432, this is what i did with the same RTH2310B thermostat and my harmon stove. You must have the heat sensor that plugs in the back of the stove to start with. Take your new wire from the stove to your thermostat, red to rh, white to one side of your sensor then other side of sensor to W on your thermostat. On your stove side set your room temp as high as it will go and let your programmable thermostat set the room temp. Works good for mine. Good Luck

Forced Hot Air Heating system doesn't maintain thermostat setting


It sounds like you may have issues with the furnace. A qualified professional can go over the system and the house to let you know if the system and unit are properly sized. The poor performance of a furnace can be a sign of carbon buildup in the furnace.
Good luck, hope this helps.

Loss of temperature control


Is the heater staying on all the time? Most likely cause of themostat trouble is the sensor. Try to find it and measure its resistance at different temps to verify the trouble.
