Operation
Scroll through the display channels by pressing
buttons 1 and 2
Accessing the adjustment channels:
Scroll down in the display menu and press
button 1 for approx. two seconds after you have
reached the last display item
When an adjustment value is shown on the
display, SET is indicated to the right of the
channel name
Press button 3 in order to access the adjustment
mode SET starts flashing
Adjust the value using buttons 1 and 2
Briefly press button 3, SET permanently appears,
the adjusted value will be saved

Please note: The controller is equipped with a
security switch-off of the store, which avoids a further
loading of the store if 95 °C is reached at the store.

Difference or deltaT collector – store [K]
Pump speed [%]
First the controller works as a standard differential controller. If the switch-on difference (DT O) is reached, the pump is activated at
full speed for 10 seconds. The speed is then reduced to the minimum pump speed value (nMN = 30 %). If the temperature difference
reaches the adjusted set value (DT S), the pump speed increases by one step (10 %). If the difference increases by 2 K (RIS), the pump
speed increases by 10 % respectively until the maximum pump speed of 100 % is reached. The response of the controller can be
adapted via the parameter „Rise“. If the temperature difference falls below the adjusted switchoff temperature difference (DT F), the
controller switches off.
