Installing the wire extender kit in a 5-wire system
1. Isolate power from the HVAC
system.
2. Familiarize yourself with the HVAC
control board located inside the air
handler system.
3. Relocate the wire from the RC
terminal on the HVAC control
board to the RC terminal on the
STAT side of the PCB assembly.
4. Connect the wire relocated from
terminal RH on the HVAC control
board to terminal RH on the STAT
side of the PCB assembly.
5. Relocate the wire from the G ter-
minal on the HVAC control board
to the G terminal on the STAT side
of the PCB assembly.
6. Connect the wire at the C terminal
of the thermostat to the C terminal
on the STAT side of the PCB
assembly.
7. Mount the PCB assembly near the
HVAC control board.
8. Connect the wire from the common
point of the diode pair to either the
W or Y terminal on the STAT side
of the PCB assembly. Ensure that
the jumper between the W and Y
terminals is installed.
9. Connect the wires between the
RC, RH, Y, W, C, and G terminals
on the HVAC control board to RC,
RH, Y, W,C and G on the EQUIP
side of the wire extender respec-
tively.
