Woke up this a.m. and noticed when I went to turn up the thermostat for the day the temp was a coup[le degrees below what it was set. I put it at 63 at night and it was 61. This is a basic non-programable Honeywell model (TH5110D1022). The readout showed heat function was active but the furnace was neither burning nor blowing. I pulled the thermostat's batteries and snapped them back in. I also pulled the unit off the wall plate and snapped it back on. I then heard the thermo click and the furnace kick on. It ran long enough to raise it two degrees then shut off. Did the same thing again and it kicked back on, warming to the set 67 degrees. I heard it come on again a little later so I assumed function was back to normal.
During today I have had to mess with it twice more. Both times I noted temps were down 3-4 degrees, and after pulling and reinserting the batteries and the wall unit, function was restored.
Does this sound like the thermostat or could it be the signal unit (for lack of a better word) on the furnace?
This is a duplex with a small 1 bedroom unit attached to the main 3 br where I live. I actually live in the whole thing and have an interior connecting door. I am waiting for it to mess up again and I am going to switch the two thermostats to see if that makes a difference. I figure if I leave the connecting door open the small unit will get adequate heat from the large. The room in the large unit with the connecting door sits right under the attic placed furnace so it runs hotter anyway.
