Economy Mechanical Heat Only Thermostat
good product,solved problem
i have a 9 zone hot water heating system and had to replace some old mercury bulb thermostats. the new thermostats without mercury wouldnt work. this cheap mechanical bi-metallic strip thermostat did the job. i wish the thermometer was more accurate and easier to read but for $12.00 you cant expect everything. i would recommend it to anyone that has problems with thermostats.

White-Rodgers 1C20-102 (Thermostat): Mechanical Direct Wired was purchased to replace one that had worn out after many years of use. It was the best price around and an excellent product that works very well for my needs.

This White-Rogers performs adequately as a thermostat, but the built-in thermometer is inaccurate. To be fair, this problem is common to all wall thermostats, including Lux and Honeywell, which are fitted with a bimetal-type thermometer. Let the buyer beware: There is no functional relationship between the thermostat's action, and the thermometer's reading. The thermometer doesn't tell the thermostat what to do. It merely reflects (inaccurately) what the thermostat is doing to room temp. My solution to this problem is to tape over or remove the little bimetal thermometer in the thermostat cover, and purchase a small bulb-type glass thermometer (far more accurate), which I mount on the wall beside the thermostat. This way, I can monitor the true room temp., and the action/ accuracy of the thermostat control.
The only other comment I have about this White-Rogers is that the placement of the red wire and white wire terminals vertically, on the left side of the base, is awkward. The more usual design is a horizontal configuration, which allows equal lengths of conductor entering the case from the bottom or back. (ie Lux, Honeywell). A good value for the money, competitive with Lux and Honeywell, and superior to RiteTemp.
