2. Set the thermostat temperature to the
desired temperature level using the
temperature selector. Please refer to
the separate detailed thermostat user’s
manual for complete instructions regarding
thermostat programming. The outdoor unit
and indoor blower will both cycle on and off
to maintain the indoor temperature at the
desired heating level.
NOTE: If the thermostat temperature level is
re-adjusted, or the thermostat system switch
is repositioned, the outdoor unit may not
start immediately. The outdoor unit contains
a protective timer circuit which holds the unit
off for approximately fi ve minutes following
a previous operation, or the interruption of
the main electrical power.
Emergency Heat:
The thermostat includes a system switch
position termed EM. HT. This is a back-up
heating mode to be used only if there is a
suspected problem with the outdoor unit. With
the system switch set to EM. HT. the outdoor
unit will be locked off, and supplemental heat
(typically electric resistance heating) will be
used as a source of heat. Sustained use of
electric resistance heat in place of the heat
pump will result in an increase in electric
utility costs.
Defrost:
During cold weather heating operation, the
outdoor unit may develop a coating of snow
and ice on the heat transfer coil. This is
