Turning OFF Furnace in AN Emergency, Phase Monitor

High Pressure Switch and Lockout Sequence

•If the high pressure switch opens, the compressor contactor will de-energize immediately. The lockout time in the CCM will go into a soft lockout and stay locked out until the high pressure switch closes and the delay on break has expired.

•If the high pressure switch opens again during the same operating cycle the CCM will go into a manual lockout condition.

•Recycling the wall thermostat resets the manual lockout.

Low Pressure Switch, Bypass and Lockout Sequence (Optional)

•If the low pressure switch opens for more than 120 seconds the compressor contactor will de- energize and the CCM will go into soft lockout.

•Regardless of the state of the low pressure switch the compressor contactor will reenergize after the delay on break time has expired.

•If the low pressure switch remains open, or opens again for longer than 120 seconds, the CCM will go into a manual lockout and the alarm relay circuit will energize.

•Recycling the wall thermostat resets the manual lockout.

NOTE: Both high and low pressure switch controls are inherently automatic reset devices. The high pressure switch opens at 425 and closes at 325 psig, and the low pressure switch opens at 14 and closes at 30 psig. The lockout features, both soft and manual, are a function of the Compressor Control Module.

Alarm Relay Output

•Alarm terminal on Compressor Control Module is 24V AC output connection for applications where signal is desired. This terminal is powered whenever compressor is in manual lockout due to high pressure or low pressure sequences as described.

PHASE MONITOR

All units with three phase scroll compressors are equipped with a three phase line monitor to prevent compressor damage due to phase reversal.

The phase monitor in this unit is equipped with two LEDs. If the “&” signal is present at the phase monitor and phases are correct, the green LED will light.

If phases are reversed, the red fault LED will be lit and compressor operation is inhibited.

3.3MANUAL FAN (CONTINUOUS AIRFLOW) OPERATION

If wall thermostat is set to MANUAL (ON) position to operate comfort air blower continuously to provide air circulation throughout the building, the blower will operate on the heating speed rather than the cooling as is typical with most systems. This permits the air to circulate as desired but helps keep the operating noise level down as well a conserving energy.

During a call for cooling, the blower automatically shifts up to cooling speed, and remains there until 60 seconds after thermostat is satisfied then drops back to heating speed.

SECTION 4 • TURNING OFF FURNACE IN AN EMERGENCY

WARNING

Have a qualified installer, service agency or gas supplier teach you location and operation of gas and electrical shut-off devices. Ask them any questions you have about this section. If you don’t turn off your furnace in an emergency damage, injury or death could result.
