THERMOSTAT CONTROL
OPERATION
The thermostatic control used on these
models differs from standard thermostats.
Standard thermostats simply turn on and off
the burner. The thermostat used on this heater
senses the room temperature. At times the
room may exceed the set temperature. If so,
the burner will shut off. The burner will cycle
back on when room temperature drops below
the set temperature. The control knob can
be set to any heat level between 1 and 5. All
plaques will turn off and on.
Note:
The thermostat sensing bulb mea
-
sures the temperature of air near the heater
cabinet. This may not always agree with
room temperature (depending on housing
construction, installation location, room size,
open air temperatures, etc.) Frequent use of
your heater will let you determine your own
comfort levels.
