THERMOSTAT
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 ex
-
ceed the set temperature. If so, the burner will
shut off. The burner will cycle back on when
room temperature drops below the set tempera
-
ture. For standard models (T), the control knob
can be set to any heating level between 1 and 5.
All plaques will turn off and on. For infrastat
models (ITA), the control knob can be set at
the 1, 2, 3 or 4 locked positions for the desired
comfort level. The number of plaques selected
will turn off and on.
Note: The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
This may not always agree with room tem
-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.) Frequent use of your heater will
let you determine your own comfort levels.
