lower than the current room temperature and the system enters
cooling mode to cool down the room.
●If the system has reached setpoint and is idle, the slider color stays
white.
NOTE
: The condition of switching between heating and cooling modes
is that the thermostat has been configured accordingly and then the
thermostat responds based on the background logical processing of the
comparison between the current room temperature and the heating and
cooling setpoint for the current mode.
Relative room humidity
The thermostat operates under a schedule. If a schedule has not been
set, the thermostat operates with the default schedule. This default
schedule may be the system default or may be specific under
“Advanced Settings” > “Optimization”.
When this icon is toggled on, the temporary change of the temperature
setpoint and fan settings only takes effect during the current scheduled
mode and will be overridden to the scheduled settings when the next
scheduled mode starts.
NOTE:
If the thermostat has not been connected to a WLAN network, it
cannot read the real time from the network and thus cannot follow a
schedule. In this case, it always works under the “Comfort” mode.

3.1 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 detects occupancy and then does the following:
●Activates idle display. When no operations are performed, the thermostat
detects presence in room. Upon presence, it displays information such as room
temperature, room air quality and relative room humidity. If unoccupied, it turns
off the screen.
●Changes the operating mode from “Unoccupied” to “Comfort”. If presence is
detected in a formerly unoccupied room during a scheduled “Unoccupied”
period, the thermostat switches to “Comfort” automatically until the next
scheduled mode starts. However, this function is disabled by default and must
be enabled manually if so desired.

main unit
4.1 Temperature control
The 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 and/or cooling equipment. If no external room temperature
sensor is connected or if the input value of the external sensor is invalid, only the
built-in sensor is used to provide values for the thermostat. If the external sensor is
connected and can provide valid values with the built-in sensor, the thermostat
displays the average value of the built-in and external sensors.
On the home screen, the current room temperature is displayed and the
temperature setpoint can be changed as desired. The units can be selected
between °C and °F (the default unit).
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 .
