*On every application, 24VAC loads should be reviewed to be sure the indoor unit control power transformer is adequately sized.
NOTE: Use 18-gauge color-coded thermostat cable for proper wiring. Shielded cable is not typically required.
Keep this wiring at least one foot away from large inductive loads such as Electronic Air Cleaners, motors, line starters, lighting ballasts and
large distribution panels. Failure to follow these wiring practices may introduce electrical interference (noise) which can cause erratic system
operation.
All unused thermostat wire to be grounded at indoor unit chassis ground only. Shielded cable may be required if the above wiring guidelines
cannot be met. Ground only one end of the shield to the system chassis.

Installation
4.1
Location
The 103 is designed for installation in climate controlled living
spaces. Place the unit in a central location with good circulation.
For proper temperature sensing, avoid exposing the 103 to heat
radiated from lamps, sun light, fireplaces or any other radiant heat
source.
Avoid locations close to windows, behind doors or alcoves with
poor air circulation, adjoining outside walls, or doors that lead to
the outside.
Select a location that prevents the 103 from being directly exposed
to air currents from supply registers or ceiling fans.
Mount the Control on a section of interior wall that does not
contain hot or cold water pipes or duct work.
