COMPRESSORS AND INDOOR FANS MODES OF OPERATION
3.2.2
Enable the Multi Input assigned to the Compressors via S.Configuration screen
Gfc8
:
NOTES:
◦
For "W- 3 Phase Sequence Relay Option", Multi Input 2 (U12) is already used for 24VAC supply. Hence,
enable Multi Input 1 (U11) instead.

NOTE: The Compressors are now configured/ready to be controlled through the external 0-10VDC input.
3.2.4
Connect the 0-10VDC staging supply to the configured Multi Input (refer to Unit’s wiring diagram).
3.2.5
Turn On the unit through the Control Interface and provide the required compressor capacity through
the 3rd Party controller 0-10VDC.
Examples of equivalent voltage and capacity scaling are as follows:
◦
3V = 33% capacity (stage 1)
◦
6V = 66% capacity (stage 2)
◦
9V = 100% capacity (stage 3)
NOTES:
◦
The Heat / Cool change over can be controlled by providing a 24VAC digital input to the controller through
the terminal of the control box (refer to wiring diagram).
◦
Ensure that the Control Interface is set for "AUTO CHANGE OVER" (under menu
C1
mode of operation).
◦
The requested external capacity value will be displayed on the status menu as Voltage x 100.
e.g. 3.3 volts will be seen as 330 on the capacity status screen.

3.3 Compressors 24VAC External Control Mode
In this mode, the Compressors are configured for request through 24VAC input from the external controller.
Configuration Procedure:
3.3.1
Ensure that the mode of operation is set to “External Input” via Service menu.
(Please see Step
3.2.1
above).
3.3.2
Connect the stage inputs to the Stage 1, 2, 3 and Heat inputs in the control box (refer to wiring diagram).
3.1.3
Make sure the Multi Input assigned to the Compressors via S.Configuration screen
Gfc8
is disabled.
