I recently installed a Honewell programmable thermostat. The manual says "model number CT3500/CT3595". While this device seems to keep the house at the target temperature, I find it odd that it can turns on when the temperatue is already stated as being the target temperature. Note: I have "Smart Response" DISABLED.
A "Hunter" programmable thermostat that I used to own, had a clearly understanable algorithm for turning on/off. The Hunter device would call for cooling if the temperature hit 1 degree above the intended temperature for, say 10 seconds. The Hunter device would then shut off the system if the temperature got 1 degree below the intended temperature for, say, 10 seconds.
I don't understand the algorithm for the Honewell. It seems odd that it would call for cooling if the room temperature is already at the target temperature. I'm just curious if anyone knows why they designed it that way. I'm just hoping that during extreme weather, this Honeywell device isn't going to be causing the system to cycle on/off more than necessary.
