Freeze Protection
The Freeze protection feature will not allow the room
temperature to drop below predefined cut-in temperature.
Depending on which configuration the system is operating
under (W/WO Heat pump) this feature will force the
system to operate in heat mode and activate the fan.
This feature will take effect when the thermostat is either
ON or OFF. When the room temperature rises above the
predefined cut-out temperature, the thermostat will return
to its previous state.
When freeze protection is activated, the display alternates
between “AL” and room temperature.

Sleep mode
Press and hold the [mode] button for 5 seconds to activate sleep mode.
Press the mode button again (short press) to deactivate sleep mode.
When sleep mode is activated, the thermostat will use comfort set point
temperatures offset set by technician.
Please refer to objects “SleepCoolSetpointOffset” and
“SleepHeatSetpointOffset” in the technician setting section of this manual.
Economy mode
Economy mode can be activated by triggering the window
contact, the door switch or the PIR sensor (passive
infrared sensor).
When Economy mode is active, the thermostat will use
special economy set points for cooling and heating set by
technician.
Please refer to objects “EconomySetpointinHeat” and
“EconomySetpointinCool” in the technician setting section
of this manual.

Installation
The ETNC24 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 and where the built in PIR
occupancy sensor can easily detect any movement in the room (consider PIR detection are below).
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 bottom tabs and then the top tongue.
Push until tight against the wall.
