Since the room temperature sensor is in the
remote controller, the remote controller box
should be installed in a place away from direct
sunlight, high humidity and direct supply of
cold air to maintain proper space temperature.
Install the remote controller about 5ft(1.5m)
above the floor in an area with good air circu-
lation at an average temperature.
Do not install the remote controller where it
can be affected by:
- Drafts, or dead spots behind doors and in
corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Uncontrolled areas such as an outside wall
behind the remote controller.
- This remote controller is equipped with LCD
display. For proper display of the remote con-
troller LCD's, the remote controller should be
installed properly as shown in Fig.1. (The
standard height is 4~5 ft (1.2~1.5 m) from
floor level.)
