Question about Honeywell Heating & Cooling

1 Answer

My Honeywell T87F Thermostat doesn't shut the A/C off when the temp in the room gets down to the Thermostat setting. I have it set on COOL and AUTO. I have to shut the A/C off; then later turn it back on as it gets warmer again.

Remove the thermostat and disconnect the r and y connection. If the A/C continues to run ya got a short in the wiring somewhere. If it shuts down then your tstat is hooped.

Thermostat does not reach programmed temperature


Have you checked with a thermometer to see if the area is reaching the temp you have it set at? A thermostat has nothing to do with the temp in your house. If you have it set at a temp for Example ( 72 ) and it is not reaching that temp to shut off then you have a problem with your unit or insulation in house. If you set stat on cool at 72 and the house gets down lower than 72 then there is a problem with stat.

Can't get my Simple Comfort 7890-DHW thermostat to set on heat. Tried the mode/program and have made it worse.


Push up or down arrow once. H will flash, this is heat setting. Set your temp. Then C will flash, this cool temp. Set your cool temp. After short delay stat will go back to display room temp. Red light heat is on. Green light cool is on. Hope that helps
