APPENDIX 1 - COMPATIBILITY AND FAN SPEED WIRING
The 24V Interface Kit is compatible with most single stage conventional 24V thermostats matched with the conventional fan coils listed in
Tables 17, 18, and 19. Before installation, check the compatibility of your outdoor and indoor fan coil. Professional installation is
recommended. For Ductless indoor units compatibility, refer to the Compatibility Charts on HVACpartners.com for the proper matches and
serial numbers.
Select Proper Blower Speed For the Fan Coil
Before operating the unit, ensure that the proper blower speed has been selected. Fan speeds are selected manually. Refer to the indoor unit’s
installation manual for instructions on how to change the fan speed and select the taps (see Tables 17, 18, and 19) for the proper matches.
24V Interface Fan Speed Wiring (See “WIRING” on page 11 for Wiring Connections)
G3 is the High Fan Speed terminal and should be connected to the high tap speed inputs at the fan coil.
G2 is the Medium Fan Speed terminal and should be connected to the medium tap speed inputs at the fan coil.
Tap G1 is the Low Fan Speed terminal and should be connected to the low tap speed inputs at the fan coil. The 24V interface may be connected
to a low Tap Speed, based on the indoor unit’s installation instructions.
