Installation
The ETN24-SUPER-SH-F 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. Cold or warm air draughts; radiant heat and direct
sunlight should be avoided.
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 located in the top of the unit and
pull the back panel out.
B. Line the back panel up against the wall or flat surface. Install three screws as required.
C. Make electrical connections as shown on enclosed electrical wiring diagram.
D. Install the cove to the back panel; first the two tabs on the bottom and then the top tongue. Push
until tight against the wall.
