Question about Honeywell Programmable Thermostat Heater

1 Answer

Readings disappear on thermostat for awhile then come back

This is a Honeywell nonprogrammable thermostat. This is a vacation home. Temp was set during our absence at 51 degrees. When I visited the house I turned the thermostat up to 64. I happened to look at the thermostat about one-half hour later and the readout was blank- nothing on the dial. Later the numbers came back into view and the heat was working.
Should I worry that the thermostat is not reading the room temp if/when the readout goes blank? W/o heat, the house pipes will freeze. If needed, I'll call a repairman to replace the thermostat unless the readout has nothing to do with the thermostat sensing the temp. This happened once before but it lasted just a few minutes. In both cases when I noted the readout was blank, I did not notice if the heater was running.

    My house is starting to get cold but the buttons don't work and the numbers dissapeared. Should I be worried?? Or will it come back on all on it's own???

Hi Linda,

There are a few things that cause this:

  1. When the heat is starting, it will sometimes go blank for a few minutes and then resume.
  2. Most have batteries, replace them with fresh new ones, if the electricity goes out while you are away, the batteries will keep the settings.
  3. Have someone check the house when it is extremely cold or hire a service to monitor. Your alarm company can usually add temperature sensors to your home, it will add a little safety net for you.
Hope this was helpful, please rate my answer.
Thanks,
Paul

What is the model number of the thermostat? What may be happening is the humidity control is trying to satisfy the humidity setting by running the a/c. In the installers set-up, there should be a setting to determine how long the system should run to satisfy humidity setting. I typically set thermostats for a 3 degree droop. Meaning it'll only drop 3 degrees below set temp. Also check your humidity setting to be sure it's not set too low. It should be set between 45% and 50%.

The unit says the indoor temp is 5 degrees higher than the actual temp in the house. Is there a way to calibrate the temp?

My round Honeywell T-87 on the main floor(middle) of the house has no ON/OFF switch. It controls the temp of that level of the house and even though it is set at 60, the temp is way too high and reads 74....


What you are describing is the Heat Anticipator. It is a small resistor that helps the thermostat from overshooting the set temperature by heating up and shutting off the thermostat just before your set temperature. I don't think that is related to your over heat. 14 degrees is a lot and the Heat Anticipator will only effect it 4 or 5 degrees. I would remove the thermostat and check if there is a call for heat. If so, you have a shorted wire. If not, replace the thermostat.

Message: "in recovery"


the "in recovery mode" is refering to a thing called energy recovery management its one of the features on your tstat what it does- when you are using the program on your tstat the "in recovery" starts your unit early so if the tstat is set to be 70 degrees at 8 in the morning when 8 o clock hits it will already be 70 degrees in your house you can turn this feature off if you want in the installation setup codes

Honeywell Digital Thermostat won't click on if temp is below 59


do you live there? if so here are the rules for setting back temperature: do not lower the temperature more than 8 degrees F from the temperature you want it when your there, setting it back for periods of less than eight hours is also somewhat futile. Due to laws of thermo-dynamics the heat required to recover from more extreme setbacks or shorter periods of time exceeds the savings acquired by taking said action. As to your question directly there are no reasons why your thermostat should not function at any setpoint temperature that it is allowed to set to (45 normally being the lowest) if it does not function below 58 degrees it has a failure and should be replaced before it fails completely. Suggest a Robertshaw or Braeburn brand thermostat, Honeywell quality has slipped over the past decade to unacceptable levels. Unless your considering a Hunter in which case buy another Honeywell.

Temp shows 2 degrees warmer than what is was set to


sometimes the furnace does a better job than anticipated, i wouldn't worry about it, especially if the furnace shuts off.
the setpoint is the temperature you want it to be
cycle lenghts are determined by how much recovery you are requesting. for instance, in the morning when you wake up, you want the temperature to be at its setpoint. what the thermostat will do is make the furnace run a limited lengths during the recovery process.
