Honeywell CT410B..will it work with ceiling heat too?
Background, we're in the process of selling my mother-in-law's 1962 ranch house with GE ceiling radiant heat. Inspector was not famaliar with the system and his write up scared the buyers. The old thermostats all worked but ran about 10 degrees hot. They insisted on new digital thermostats.
As with yours the old thermostats were single pole, 2-wire (only one black and one red wire), rated at 120/240 V 22 amps (5000W). I could not find any digital thermostats rated above 4000W. So I checked each line with a clamp meter (bought at Lowe's) and found that of the 11 room circuits the highest load was about 9.5 amps, the lowest was 2 amps. While I was doing this I discovered that the red wire on each circuit had a crimped on label stamped with model number, voltage, and power. Sure enough the circuit with the 9.5 amp load was labeled 2300W and the 2 amp circuit was labeled 500W.
I purchased and installed Aube (Honeywell) TH401 non-programmable digital thermostats rated for 120/240V 2500W. I found them online for less than $30 each.
They work well, accurate and silent.
That's my recent experience. I need more information to help with your specific question as to the CT410B. You mention that your system is single pole (single line break) but you did not mention if it was single pole 2-wire or single pole 4-wire.
