2nd Stage (Y2):
If space temperature continues to rise,
thermostat Y2 demand will be initiated. Contact Y2 will
close, sending a 24--v signal to CTB’s TSTAT terminal
strip at Y2. An internal path passes this signal to
connector DDC/TSTAT pin 6. A harness wire carries this
signal to Fan Speed Relay board pin J1--3. Relay K2 is
energized. The relay board’s output to VFD at pin J2--2 is
de--energized and the output at J2--3 is energized, causing
the VFD to shift its output to the indoor fan motor to
60HZ. The indoor fan motor ramps up to full/high speed
operation.
When the space temperature drops to satisfy thermostat
Y2 demand, contact Y2 opens de--energizing terminal Y2.
Relay K2 is de--energized, removing the VFD input at
terminal 15. Fan Speed Board output at pin J2--2 is
restored to the VFD at terminal 14; VFD shifts back to
40HZ output to the indoor fan motor and motor shifts
back to reduced speed operation.
Heating
When the thermostat initiates a call for 1st Stage Heating
by closing its W1 contacts, a 24--v signal is conveyed to
the CTB’s TSTAT terminal strip at W1. An internal path
passes this signal to connector DDC/TSTAT pin 5. A
harness wire carries this signal to Fan Speed Relay board
pin J1--2. Relay K1 is energized. The relay board’s output
to VFD at pin J2--3 is energized, providing a 24--VDC
signal to VFD terminal 15. The VFD starts the indoor fan
motor, runs at 60HZ for full/high speed operation.
When space temperature rises to satisfy the thermostat
W1 demand, contact W1 opens de--energizing terminal
W1. Relay K1 is de--energized. The relay board output at
J2--3 to the VFD is removed.
40RU, 50--Series:
Indoor fan motor ramps down to stop.
48--Series:
The IGC’s fan--off delay sequence will energize
relay K3 for 45--seconds, causing the VFD to operate the
indoor fan motor at 40HZ (low speed) for 45--seconds, then
indoor fan motor will ramp down to stop.
