The "White Dial" Furnace Thermometer reads the furnace temperature in any outdoor boiler (including all GH and HE model furnaces) and meets the specifications to give temp readings. This thermometer does not control any instruments, it is for information purposes only for the user.

This thermometer ships with a well if needed, but for existing furnaces, the thermometer just slides into the existing well.
