Pros & Cons
Pros
Rth221b programmable thermostat is easy to use. This product is made by honeywell's entry level reprogrammable home heating & cooling thermostat. Replaced an old round mercury switch.
My flashlight works if i hold it correctly. This one is easy to read.
Cons
As soon as weather gets below 32 degrees f the thermostat reads lo (lock out) and won't work. The screws were so tight that the screwdriver in the repair kit did nothing to make it move.

There was some problem with its thermometer if i set it to 65 degrees the heat would come on for a second but shut off and i’d have to go reset the heater itself to make it fire back up
