Power Wiring From Building to Unit
1. Locate the electrical power supply wiring from the
building and feed wiring through the 1/2" conduit
tting (strain relief) on the unit as shown in Figure
27 & 28, following local electrical codes and
regulations.

2. If a remote wall-mounted thermostat is being used,
install a 24-volt thermostat wiring cable with at
least 6 wires from the unit low voltage terminal strip
(Figure 29) to the thermostat location.
3. If a wireless remote thermostat was ordered to
control the unit, it is recommended that the Remote
Control Node (RCN) be installed now.
