Where can I find digital thermostats for electric baseboard heating?
If you do not require a night-setback, use a Honeywell model TL235A1003. I have not found a decent line-voltage night setback thermostat. I recommend using a low-voltage electric heat relay with any standard setback thermostat. A low voltage electric heat relay (i.e. Honeywell 841 series) will include a 24 volt transformer to power the thermostat, plus have a line voltage relay to switch the heat on and off. This type of device is not typically sold at Home Depot or Lowes. Go to your local electical supply house (where the electricians go) and tell the counter man what you are trying to do. He will set you up.
