Behaviour after switching on the mains
voltage
After switching on the mains voltage, the LED (B)
lights permanently green.
If the device has not yet been connected, pairing 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. In
this time, all heating zones are triggered and the channel
LED lights permanently.
In the following 20 minutes, the valves are operated via
two-point control. If the temperature falls below the
setpoint temperature, the valves are switched on. If the
setpoint temperature is increased, the valves are switched
off. After 20 minutes, the valves are operated via PI
control with PWM output (normal operation).
