Thermostat
Room thermostats are delicate temperature sensing
controls. Their main function is to energize and de-energize
the heating or cooling circuit to maintain the temperature
setting you select.
Many thermostats contain a room thermometer to indicate
the approximate room temperature and a temperature
scale at the adjustment indicator to select the desired
indoor air temperature. In addition, most thermostats have
a selector mode switch with Heat, Off and Cool positions
and a fan switch with On and Off positions.
When the switch is positioned at Off your unit will not
operate in either the heat or cool modes. If the selector
switch is set at Heat the unit will automatically cycle on and
off to maintain the desired temperature setting. The unit will
also operate automatically when the selector switch is
positioned at Cool.
The fan selector switch can be used to operate the indoor
fan continuously by positioning it at On. When set to Auto
the fan will only operate when required during the heating
or cooling cycles.
To ensure that the thermostat operates properly, it must be
level and positioned to avoid the influence of such external
heat sources as lamps, televisions or other heat producing
appliances.
