The ALT/X500 room panel is designed for wall mounting in the
room to be controlled.
It should be located where the occupant can easily read the
LCD display and use the controls.
If the built in temperature sensor is being used to measure
room temperature, the module should be placed where the
temperature is representative of the general room conditions.
General points to follow:
- Disconnect power to the main board before installing the unit.
- The standard height to install this unit is 1.5 meter (5 feet)
from the floor.
Installation procedure:
A. Separate the front panel from back panel by pressing
the tongue on the top and pulling the back panel out.
B. Line the back panel up against the wall or flat surface.
Install three screws as required.
