Page 10: Commissioning
3. Commissioning Î Establish the power supply During a short initialization phase, the operating control lamp flashes red and green. When the controller is commissioned for the first time or after a reset, it will run a commissioning menu. The commissioning menu leads the user through the most important adjustment channels needed for operating the system. -

Page 13: Adjustment Channels
4.2 Adjustment channels ∆T-regulation The controller works as a standard differential controller. If the switch-on difference is reached, the pump is activated. When DT O: the temperature difference falls below the adjusted switch-off Switch-on temperature diff. temperature difference, the relay switches off. Adjustment range: 2.0 ... - Page 14 Maximum tank temperature Once the adjusted maximum temperature is exceeded, the solar pump is switched off and further loading of the S MX: tank is prevented to reduce scald risk or system damage. A Maximum tank temp. fixed hysteresis of 4 °Ra [2 K] is set for the maximum tank Adjustment range: temperature.
