GAS HEATInG / ELECTrIC COOLInG UnITS

ABOUT THE GAS HEATInG / ELECTrIC

COOLING UNIT

This gas heating unit with electric cooling has been designed and built to provide many years of safe and dependable comfort, providing it is properly installed and maintained. With regular maintenance, this unit will operate satisfactorily year after year.

Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards. A regular service and maintenance schedule should be established to ensure efficient and safe operation of the unit. See System

Maintenance on page 5

WARNING:

If overheating occurs, or the gas supply fails to shut off, shut off the gas valve to the unit before shutting off the electrical supply.

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’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)

1. Set the thermostat system mode to COOL and the thermostat fan mode to AUTO. See Figure 1.

2. 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.

For 2-Stage Models Only:

If Stage 1 cool does not satisfy the thermostat demand, stage 2 cool will energize. The outdoor compressor and indoor blower will ramp to high speed.

System Shutdown

Set the thermostat system mode to OFF (see Figure 1) and the thermostat fan mode to AUTO.

NOTE:

The system will not operate, regardless of the thermostat temperature selector’s setting.

Continuous Indoor Blower Operation

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 to ON (see Figure 1). The indoor blower will start immediately and will run continually until the fan switch is reset to AUTO.

NOTE:

On some thermostat models the setting may be called CONT.

The continuous indoor blower operation can be obtained with the thermostat system switch set in any position, including OFF.

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. 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 (1 or 2 Stage Operation)

1. Set the thermostat system mode to Heat and the thermostat fan mode to AUTO. See Figure 1.

2. Set the thermostat temperature selector to the desired temperature level. The indoor blower and gas heat module will cycle on and off to maintain the indoor temperature at the desired heating level.

DUAL FUEL UnITS - GAS HEAT / ELECTrIC HEAT PUMP

ABOUT THE HEAT PUMP

(Dual Fuel Models Only)

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 this basic law 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

A thermostat with fossil fuel back-up heat capability is required to operate the Dual Fuel iHybrid™ heat pump system. 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.

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’s User Manual for detailed programming instructions.

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)

1. Set the thermostat system mode to COOL and the thermostat fan mode to AUTO. See Figure 1.

2. 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: If Stage 1 cool does not satisfy the thermostat demand, stage 2 cool will energize. The outdoor compressor and indoor blower will ramp to high 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 Stage 1 heat does not satisfy the thermostat demand, stage

2 heat will energize. The outdoor compressor and indoor blower will ramp to high 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 gas heat will operate until the thermostat demand for heat is met.

Emergency Heat - Gas 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 the gas furnace will be used as a source of heat. Sustained use of gas 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 features

Demand Defrost that monitors 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 gas funace 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 gas furnace continues to operate and the blower speed increases.

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 gas heat will shut down at the end of the defrost cycle.

Automatic Heat Pump Operation (Cooling & Heating)

1. Set the thermostat system mode to AUTO and the thermostat fan mode to AUTO. See Figure 1 (page 3).

2. 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.

Continuous Indoor Blower Operation

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 to ON (see Figure 1). The indoor blower will start immediately and will run continually until the fan switch is reset to AUTO.

NOTE:

On some thermostat models the setting may be called CONT.

Continuous indoor blower operation can be obtained with the thermostat system switch set in any position, including OFF.

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.
