6.3 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, teach-in mode will be activated
during the first 3 minutes after the mains voltage has been switched on.
You will find further information 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 trig-
gered and the channel LED lights permanently.
In the following 20 minutes, the valves are operated via two-point con-
trol. If the temperature falls below the setpoint temperature, the valves
are switched on. If the setpoint temperature is increased, the valves are
switched o. After 20 minutes, the valves are operated via PI control with
PWM output (normal operation).
