COOLING UNITS
ABOUT THE COOLING UNIT
The single packaged electric cooling unit is a high efficient self contained
appliance that will cool your home and provide energy saving comfort.
Additional features and benefits of the cooling include:
• Indoor and outdoor coils are designed to optimize heat transfer, minimize
size and cost, and increase durability and reliability.
• Environmentally friendly R-410A Refrigerant.
OPERATING INSTRUCTIONS
Thermostat styles vary. Some models may not include the AUTO mode and others
will have the AUTO in place of the HEAT and COOL. Others may include all
three. Please refer to the thermostat manufacturer’s User manual for detailed
programming instructions.
The thermostat should be mounted about 5 feet above the floor on an inside
wall and not on an outside wall or other location where its operation may be
adversely affected by radiant heat from fireplaces, sunlight, or lighting
fixtures, and convective heat from warm air registers or electrical
appliances.
Cooling Operation – 1 or 2-Stage Operation
- Set the thermostat system mode to COOL and the thermostat fan mode to AUTO. See Figure 1.
- Set the thermostat temperature selector to the desired temperature level. The outdoor fan, compressor, and indoor blower will all cycle on and off to maintain the indoor temperature at the desired cooling level.
NOTES :
• On some select models, if the cooling level is not satisifed by the thermostat in stage 1, the thermostat will initiate to stage 2 and the indoor blower will ramp to a higher speed.
• If the temperature level is re-adjusted, or the system mode is reset, the fan and compressor in the outdoor unit may not start immediately. There may be a protective timer circuit in the thermostat which holds the compressor and the outdoor fan off for approximately 5 minutes following a previous operation or the interruption of the main electrical power.
Heating Operation – Optional Electric Heat
- Set the thermostat system mode to Heat and the thermostat fan mode to AUTO. See Figure 1.
- Set the thermostat temperature selector to the desired temperature level. The indoor blower or electric heat module will cycle on and off to maintain the indoor temperature at the desired heating level.
System Shutdown
Set the thermostat system mode to OFF and the thermostat fan mode to AUTO. See
Figure 1. NOTE: The system will not operate, regardless of the thermostat
temperature selector’s setting.
Operating the Indoor Blower Continuously
Set the thermostat fan mode to ON (or CONT on some thermostat models). See
Figure 1.
The indoor blower will start immediately, and will run continually until the
fan mode is reset to AUTO.
The continuous indoor blower operation can be obtained with the thermostat
system mode set in any position, including OFF.
The continuous indoor blower operation is typically used to circulate the
indoor air to equalize a temperature imbalance due to a solar load, cooking,
or fireplace operation.
HEAT PUMP UNITS
ABOUT THE HEAT PUMP
Your heat pump is a unique, all weather comfort-control appliance that will
heat and cool your building year round and provide energy saving comfort. It’s
an unknown fact that heat is always in the air, even when the outside
temperature is below freezing.
The heat pump uses basic laws of physics to provide energy saving heat during
the winter months.
In colder temperatures, the heat pump performs like an air conditioner run in
reverse. Available heat energy outside the building is absorbed by the
refrigerant and exhausted inside.
This efficient process means you only pay for “moving” the heat from the
outdoors to the indoor area. You do not pay to generate the heat, as is the
case with more traditional furnace designs.
During summer, the heat pump reverses the flow of the heatabsorbing
refrigerant to become an energy-efficient, central air conditioner. Excess
heat energy inside the home is absorbed by the refrigerant and exhausted
outside the building.
OPERATING INSTRUCTIONS
Thermostat styles vary. Some models will not include the AUTO mode and others
will have the AUTO in place of the HEAT and COOL. Others may include all
three. Please refer to the thermostat manufacturer’s User Manual for detailed
programming instructions.
The thermostat should be mounted about 5 feet above the floor on an inside
wall and not on an outside wall or other location where its operation may be
adversely affected by radiant heat from fireplaces, sunlight, or lighting
fixtures, and convective heat from warm air registers or electrical
appliances.
NOTE: If the temperature level is re-adjusted, or the system mode is reset,
the fan and compressor in the outdoor unit may not start immediately. A
protective timer circuit holds the compressor and the outdoor fan off for
approximately 5 minutes following a
previous operation or the interruption of the main electrical power.
Cooling Operation (1 or 2 Stage Operation)
- Set the thermostat system mode to COOL and the thermostat fan mode to AUTO. See Figure 1.
- Set the thermostat temperature selector to the desired temperature level. The outdoor fan, compressor, and indoor blower will all cycle on and off to maintain the indoor temperature at the desired cooling level.
NOTE: On some select models, if the cooling level is not satisifed by the thermostat in stage 1, the thermostat will initiate to stage 2 and the indoor blower will ramp to a higher speed.
Heating Operation – Heat Pump Mode
1. Set the thermostat’s system mode to HEAT or AUTO and change the fan mode
to AUTO. See Figure 1 (pg 3).
2. Set the temperature selector to the desired temperature level. The
compressor, outdoor fan, and blower motor will cycle on and off to maintain
the indoor temperature at the desired heating level.
NOTES :
- If the heating level is not satisifed by the thermostat in stage 1, the thermostat will initiate to stage 2 and the indoor blower will ramp to a higher speed.
- On some thermostats, if the heating load on the conditioned space is not met in a normal period of time or the difference between the thermostat set point and room temperature is large, the heat pump will automatically shut off and the electric heat will operate until the thermostat demand for heat is met.
Emergency Heat – Electric Heat mode
Heat pump thermostats include a system mode called EM HT or AUX HT, etc. This
is a back-up heating mode that should only be used if a problem is suspected.
With the mode set to EM HT, etc., the compressor and outdoor fan will be
locked off and electric heat will be used as a source of heat. Sustained use
of electric heat in place of the heat pump will result in an increase in this
utility cost. Refer to the thermostat manual for more info.
Defrost Operation
During cold weather heating operation, the outdoor unit will develop a coating
of snow and ice on the heat transfer coil. This is normal and the unit will
defrost itself. This unit will monitor ambient and coil temperatures to
regulate the defrost function
accordingly.
At the beginning of the defrost cycle, both the outdoor condenser fan and
compressor will turn off. After approximately 30 seconds, the compressor will
turn on and begin to heat the outdoor coil causing the ice and snow to melt.
During the defrost period, the electric heat will energize and produce warm
air to offset the heat pump operation while in its reverse cycle. Initially
the air out of the supply registers may be slightly cooler since the heat pump
has reversed its cycle and is now in the cooling mode to aide in the
defrosting of the outdoor coil. The air will rise in temperature as the
electric heat continues to operate.
NOTE: While the ice and snow is melting, some steam may rise from the outdoor
unit as the warm coil causes the melting frost to evaporate. When defrost is
completed, the outdoor fan motor will start, and the compressor will turn off
again. In approximately 30 seconds the compressor will start up again and
continue normal operation. The electric heat will shut down at the end of the
defrost cycle.
Automatic Cooling & Heating Operation
- Set the thermostat system mode to AUTO and the thermostat fan mode to AUTO. See Figure 1 (page 3).
- Set the thermostat’s temperature selector to the desired heating and cooling temperature level(s). The outdoor unit and the indoor blower will then cycle on and off in either the heating or cooling mode of operation as required to automatically maintain the indoor temperature within the desired limits.
Operating the Indoor Blower Continuously
The continuous indoor blower operation is typically used to circulate the
indoor air to equalize a temperature imbalance due to a solar load, cooking,
or fireplace operation. Set the thermostat fan mode (Figure 1) to ON (or CONT
on some thermostat models). The indoor blower will start immediately, and will
run continually until the fan mode is reset to AUTO.
The continuous indoor blower operation can be obtained with the thermostat
system mode set in any position, including OFF.
System Shutdown
Set the thermostat system mode (Figure 1) to OFF and the thermostat fan mode
to AUTO. NOTE: The system will not operate, regardless of the thermostat
temperature selector’s setting.
