9.1 AIRFLOW PERFORMANCE DATA
10.0 SEQUENCE OF OPERATION
10.1 COOLING (cooling only or heat pump)
• In a serial communicating network:
When the thermostat “calls for cooling,” a cooling command is sent via the serial net-
work to the air handler and outdoor unit.
• Using conventional 24VAC thermostat wiring:
When the thermostat “calls for cooling,” the circuit between R and Y is completed.
A “call for cooling” causes:
1) The blower to start.
2) The compressor relay to close energizing the compressor.
3) The outdoor fan motor to start.
10.2 HEATING (electric heat only)
• In a serial communicating network:
When the thermostat “calls for heat,” a heating command is sent via the serial net-
work to the air handler.
• Using conventional 24VAC thermostat wiring:
When the thermostat “calls for heat,” the circuit between R and W is completed.
A “call for heat” causes:
1) The heater sequencer (HR1) energizes.
2) A timed delay begins.
3) The indoor blower motor (IBM) starts.
4) The heating elements (HE) energize.
10.3 DEFROST
• For sequence of operation for defrost controls, see outdoor heat pump installation
instructions.
10.4 EMERGENCY HEAT (Heating of Heat Pump)
• If selector switch on thermostat is set to the emergency heat position, the heat pump
will be locked out of the heating circuit, and all heating will be electric heat.
