3Mounting and installation
●The thermostat is suitable for wall mounting.
●The recommended height is 1.50 m above the floor.
●Do not mount the thermostat in recesses, shelves, behind curtains or doors, or
above or near heat sources.
●Avoid direct solar radiation and drafts.
●Seal the conduit box or the installation tube if any, as air currents can affect
sensor readings.
●Adhere to allowed ambient conditions.
1. Switch off power to your heating system by using either your home’s breaker
box or the system’s power switch.
2. Remove the cover of your old thermostat.
3. Label the wires according to your old thermostat terminal designations, using
the stickers provided together with the thermostat. It is also helpful if you take a
picture of the current wire connections for reference later on.

4. Disconnect all the labeled wires and then remove your old thermostat.
NOTICE! Do not throw your old thermostat in the trash if it contains mercury in
a sealed tube. You can contact a thermostat recycling organization, for
example, www.thermostat-recycle.org, for safe disposal of your old thermostat.
5. Check whether you need to have more wires connected to the power unit to be
installed. If yes, prepare the wires and label them accordingly. Normally, at
least three wires are needed for the thermostat to work meaningfully. It is
strongly recommended that you turn to installers for wire connection.
6. Seal the conduit box or the installation tube to prevent entrance of cold or warm
air and ensure the correctness of temperature readings by the internal sensor.
7. Screw the mounting plate tightly on the conduit box using a screwdriver,
making sure that the mounting plate is placed correctly (the part with the
upward arrow is placed on the top).
8. Connect the labeled wires to the terminal tightly according to your thermostat
terminal designations (you may also refer to the picture you take in Step3), and
then fix all the inserted wires by screwing down the screws. Note that the wiring
for your application might be different from the schematic drawing shown
below.
9. Screw the power unit on the mounting plate tightly.
10. Attach the front module horizontally, making sure that each side of the front
module fully aligns with that of the power unit, and then press each corner of
the front module until you hear a click sound.

11. Switch on power to your heating system. Your thermostat powers on too.
See the Mounting instructions for more information. Note that a bridge between
one Q11 terminal and terminal L is pre-wired. It is not recommended to remove this
pre-wiring bridge unless requested.
●Comply with local regulations to wire, fuse and earth the thermostat. It is
recommended that the conduit box is connected to the earth (safety ground).
●Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device.
●The line voltage cables and signal cables should be arranged separately.
●X1, M and X2 wires operate at SELV (Safety Extra Low Voltage) level. You
must not insert cables of AC 230 V mains voltage into terminals X1, M and X2
and vice versa.
●Isolate the cables of inputs X1, M and X2 from the AC 230 V mains voltage.
●The AC 230 V mains supply line must have an external circuit breaker with a
rated current of no more than 10 A.
●You must not tear off the two insulation tapes on the lower part of the back of
the power unit; otherwise, it might cause risks of electric shock.
●Properly size the cables to the thermostat and valve actuators.
●Do screw the cables tightly and ensure that no bare copper is exposed.
●Use valve actuators rated for AC 230 V. If a valve actuator rated for AC 24 V is
used, use a transformer before connecting it to the thermostat.
●Disconnect from power supply before removing the front module and the
mounting plate.

When your thermostat is powered up for the first time, a setup wizard displays to
guide you through the following procedures:
●Setting a display language
●Setting an administrator password
●Setting up a network connection and choosing the network connection type
●Selecting an equipment type and setting up the details
●Configuring time and date
●Specifying a name to the location where the thermostat is installed

the scheduled setpoint when the next scheduled mode starts.
NOTE: If
the thermostat has never been connected to a WLAN network,
it cannot read the real time from the network and thus cannot follow a
scheduler. In this case, it always works under the Comfort

5Presence detection
5.1 Presence detection using the built-in PIR sensor
By using a built-in presence detection sensor (also called PIR (Passive infrared
detector) sensor), the thermostat can detect the space occupancy and then do the
following:
●Activate the idle display. When no operations are performed, the thermostat
detects whether someone is in the room or not. If it detects someone is in the
room, it displays information such as room temperature, room air quality and
relative room humidity. If it detects no one is in the room, it turns off the screen.
●Change the operating mode from Economy to Comfort. If an unoccupied room
is detected to be occupied when a scheduled Economy mode is running, the
thermostat switches to Comfort automatically until the next scheduled mode
starts. However, you can decide not to switch to Comfort if you want.
Sensor location

4. Drag the slider to the left.
5.2 Approach detection
The thermostat has a built-in approach sensor. It can detect someone approaching
the thermostat. If activity is sensed within 10 cm, it will switch from its idle screen to
the main home screen with full temperature and setpoint display.

6Operating your thermostat from the hardware
unit
6.1 Temperature control
Your thermostat acquires the room temperature using the built-in sensor and/or the
external room temperature sensor, and maintains the setpoint by delivering control
commands to heating equipment. On the home screen, you can see the current
room temperature and adjust the temperature setpoint as you want.
Your thermostat also allows you to select your preferable temperature unit between
°C (the default unit) and °F.
NOTICE
After the initial setup of the thermostat, the displayed room temperature may not
be correct because the temperature sensors need time for the calibration. Wait for
at least one hour for the calibration.
To adjust the temperature setpoint on the home screen
●From the Home screen, drag the temperature slider to the right to increase the
temperature setpoint, or to the left to decrease the temperature setpoint.
To change the temperature unit
1. From the Home screen, tap , and then tap .
2. Tap , then tap to change from Celsius to Fahrenheit, or tap to change
from Fahrenheit to Celsius.
