UNIT OPERATION
COOLING OPERATION
During cooling operation, the main outdoor control will receive a
communicated demand signal along with the current space
temperature and setpoint. The control algorithm will then utilize
these signals to communicate the proper compressor speed,
OD fan speed, and ID blower CFM to match system output for
the required space load.
EMERGENCY HEAT
Emergency Heating mode is defined as a compressor speed
reference of zero and the backup heat source energized. In
other words, a 'W' signal present without any 'Y' signals pres-
ent. The control energizes 'W1 OUT' immediately when an
emergency heat signal “W” is received. The control energizes
“W2 OUT” based upon the stage delay setting in the thermostat
(default 120 minutes) after the “W1 OUT” output is energized.
During emergency heating mode, the control returns to standby
mode. The control passes the “W1 OUT” back to the ID unit
automatically if no “Y” is present.
