Thermostat
NOTE: Different thermostats operate according to their particular features. Refer to thermostat
specifications for details.
DET3 Series heaters require a 24VAC, two stage thermostat to operate. The burner control box is
equipped with a round terminal strip that accepts three (3) 1/4 in. female spade terminals. Do not supply
120VAC to the 24VAC connection.
Example: Desired room temperature is 65° F. The preset differential of the thermostat is 1° F.
The preset differential for High fire mode is 3° F.
When the temperature drops below the Low Fire preset differential of the thermostat (63° F), Low Fire will
activate. If the temperature continues to drop below the preset differential for High Fire, High Fire will
activate bringing the temperature back up to the Low Fire preset quickly.
