Installation
General points to follow:
- Disconnect power to the main board before installing the unit.
- The unit should not be installed on an outside wall or where there is an air draft.
- The unit must not be exposed to a direct sunlight.
- The standard height to install this unit is 1.5 meter (5 feet) from the floor.
Installation procedure:
Separate the front panel from back panel by pressing the tongue located in the top of the unit and pull the
back panel out.
Line the back panel up against the wall or flat surface. Install three screws as required.
Make electrical connections as shown on enclosed electrical wiring diagram.
Install the cover to the back panel; first the two tabs on the bottom and then the top tongue.
Push until tight against the wall.
Before connecting or disconnecting any wires, ensure that all
power supplies have been switched off and all wires are
potential-free to prevent equipment damage and avoid
electrical shock.
Do not run wiring close to transformers or high frequency
generating equipment. Complete and verify all wiring
connections before applying power to the controller to which
the module is connected.

The ETN24 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.
