Behaviour after switching on the mains
voltage
If the device has not yet been connected, teach-in mode
will be activated during the first 3 minutes after the mains
voltage has been switched on. You will find further infor-
mation about connecting your device in the next section.
During the first 10 minutes after the mains voltage has
been switched on the device remains in start mode. Dur-
ing this time, the triac is being triggered.
During the following 20 minutes, the triac is operated via
two-point control. If the temperature falls below the set-
point temperature, the triac is switched on. If the setpoint
temperature is increased, the relay is switched off. After
20 minutes, the triac is operated via PI control with PWM
output (normal operation).
If the wall thermostat is operated stand-alone (without
further Homematic IP components), please continue to
chapter 6.

Teaching-in
Please read this entire section before starting
the teach-in procedure.
To integrate the wall thermostat into your system and
enable it to communicate with other devices, you must
teach it in first.
