THERMOSTAT
OPERATION
Since the thermostat measures the tem-
perature of air near the heater cabinet,
this may not always agree with room
temperature (depending on housing con-
struction, installation location, room size,
open air temperatures, etc.). Frequent
operation of your heater will enable you
to determine your own comfort levels.
