INTELLIZONE2
● 24V INSTALLATION MANUAL
Wiring IntelliZone2
● 24V to the Unit
WARNING: All wiring must comply with local
and state codes. Disconnect the power supply
before beginning to wire to prevent electrical
shock or equipment damage.
Follow the wiring schematic in Figure 15 for unit control
connections. Strip the wires back 1/4 inch (longer strip
lengths may cause shorts) and insert the thermostat wires
into the unit’s connector as shown in Figure 15. Tighten
the screws to ensure tight connections. Use a minimum of
18-gauge thermostat wire for connections. Use wire nuts
only for connections to thermostat wire.
1 – There is a wire harness (wire colors: black, red, white,
green) supplied with the IntelliZone2 relay board with
a connector on one end and with jacket removed on
the other end. Cut the connector off of the end. Use
these wires to connect between IntelliZone2 - P17 and
IntelliZone2
● 24V - P2 as follows:
Green = DX+ to A+
Red = R to R
Black = C to C
White = DX- to B-
2 – There is a wire harness with orange wire supplied
with the IntelliZone2
● 24V. The connector end should be
plugged into IntelliZone2
● 24V - P8 for the ‘L’ (lockout)
signal. Using field supplied thermostat wire use a wire nut
to connect to the stripped end of the orange wire and
route to the ‘L’ or ‘LO’ terminal on the heat pump control
board.
3 – Field wire IntelliZone2
● 24V - P4 to heat pump control
board P1 as shown below.
