Page 10: Circulation Mode
5 Circulation mode 5 Circulation mode The domestic hot water module is equipped with a circulation pump. Three possible operating modes are stored in the controller for operating the circulation pump (see controller instructions, page 29 ff). Pulse-controlled operation (depending on the demand / requirements): The short opening of a hot water tap (tap pulse: ~2 sec.) starts the circulation pump. -

Page 16: Commissioning Of The Controller
7 Commissioning [specialist] Commissioning of the controller WARNING Risk to life and limb due to electric shock! Check if the sensors and the pumps are properly connected to the controller and if the controller housing is closed. Only then should the mains plug of the controller be plugged into a socket. Connect the domestic hot water module to the mains (230 V, 50 Hz) using the premounted connection cable. - Page 17 7 Commissioning [specialist] Open a withdrawal point for domestic hot water (for example a tap) with a flow rate of at least 10 l/min and let the water run for about 2 minutes to deaerate the secondary circuit. Then close all withdrawal points in the secondary circuit.

Page 18: Maximum Withdrawal Flow Rate
7 Commissioning [specialist] Maximum withdrawal flow rate The following diagram shows the maximum withdrawal flow rate depending on the tank temperature with a preset hot water temperature of 45 °C at the tap. The integrated control prevents the temperature from falling as long as the maximum flow rate is not exceeded. Temperature of the buffer tank Example 2... - Page 19 7 Commissioning [specialist] The following diagram shows the maximum withdrawal flow rate depending on the tank temperature with a preset hot water temperature of 45 °C at the tap after the addition of cold water of 10 °C. The temperature of the domestic hot water adjusted at the controller is 60 °C. Temperature of the buffer tank Example 1...
