OPERATING YOUR HEAT PUMP UNIT
The operation of your heat pump system is controlled by the
indoor thermostat. You simply adjust the thermostat and it
maintains the indoor temperature at the level you select. Most
thermostats for heat pump systems have 3 controls: a temperature
control selector, a FAN control, and a SYSTEM or MODE control.
Refer to your thermostat owner’s manual for more information.
I. COOLING MODE
With the SYSTEM or MODE control set to COOL, your heat
pump will run in cooling mode until the indoor temperature is
lowered to the level you have selected. On extremely hot days,
your heat pump will run for longer periods at a time and have
shorter "off" periods than on moderate days.
II. HEATING MODE
With the SYSTEM or MODE control of your indoor thermostat set
to HEAT, your heat pump will run in heating mode until room
temperature is raised to the level you have selected. Of course,
your heat pump will have to operate for longer periods to maintain
a comfortable environment on cooler days and nights than on
moderate ones.
III. SUPPLEMENTAL HEAT
Your heat pump is your primary heating source. Your system may
also be equipped with a supplemental heating source such as
electrical heat. On cold days and nights, your system will auto-
matically turn on the supplemental heat in order to maintain the
level of comfort you have selected.
When your heat pump needs additional heat to keep you comfort-
able, your Bryant electronic thermostat will turn on the supple-
mental heat (if equipped) and display the "AUX HT" message.
IV. DEFROST MODE
When your heat pump is providing heat to your home or office and
the outdoor temperature drops below 45 °F, moisture may begin to
freeze on the surface of the coil. If allowed to build up, this ice
would impede airflow across the coil and reduce the amount of
heat absorbed from the outside air. So, to maintain energy-efficient
operation, your heat pump has an automatic defrost mode.
The defrost mode starts at a preset time interval of 30 minutes,
although, it may be reset to 60, 90 or 120 minutes. Defrost will
start at the preset time only if the ice is sufficient to interfere with
normal heating operation.
After the ice is melted from the coil, or after a maximum of 10
minutes in defrost mode, the unit automatically switches back to
normal heating operation.
Do not be alarmed if steam or fog appears at the outdoor unit
during defrost mode. Water vapor from the melting ice may
condense into a mist in the cold outside air.
During certain weather conditions such as heavy snow and
freezing rain it is not uncommon for ice to build up on the unit
grille. This is normal for these weather conditions. Do not attempt
to remove the ice from the unit grille. This condition will not affect
the proper function of the unit and will clear within a few days.
