SECTION II: THERMOSTATS
YOUR KEY TO COMFORT
Though thermostats may vary widely in appearance they are all
designed to perform the same basic function, to control the operation of
your air conditioning or heat pump system. Regardless of size or shape,
each thermostat will feature a temperature indicator; a dial, arm, or
push button for selection of the desired temperature; a fan switch to
choose the indoor fan operation; and a comfort switch for you to select
the system mode of operation.
COOLING AND HEATING (HEAT PUMP)
If your system has been designed to allow both cooling and heating
operation, you may have either a manual change-over type, or a pro-
grammable electronic type thermostat with single stage of cooling and
single stage of heat.
MANUAL CHANGE-OVER
Manual change-over simply means that the comfort switch must be
manually positioned every time you wish to switch from the cooling to
heating or heating to cooling modes of operation.
SECTION III: PROGRAMMABLE
ELECTRONIC THERMOSTATS
The computerized electronic thermostat is actually a sophisticated elec-
tronic version of a manual change-over type. This thermostat includes
features which allow "set-back" temperature variations for periods of
sleep, or while you are away during the day, and means energy savings
for you. The thermostat also features a digital clock.
