Variant menu: System Definition > Tank > Control

The majority of tank dialogs have a Control page, including one or several areas:

• Desired tank temperature
• Auxiliary heating
• Collector loop connections
• Redirection valve / Return boost

Define on the Control page:

Desired tank temperature

1. The switching temperatures for the auxiliary heating can be changed.
2. Define the desired tank temperature with respect to the DHW target temperature.
3. In the Collector Loop Connection section, the position of the measurement sensors for switching on and off the collector loop and the maximum temperature limit of the tank are displayed.

Auxiliary heating

4. Activate the checkbox “With Restricted Load Times”.
5. Then define the switching times using the clock.
6. Under “Height”, the position of the temperature sensor in the tank for regulating the boiler is displayed.

Collector loop connections

7. The positions of the measurement sensors for switching on and off and for limiting the maximum temperature are displayed and cannot be changed.
8. If the tank is used as a solar tank, the maximum temperature limit of the tank can be changed.

Redirection valve / Return boost

9. On the Control page, the single coil heating buffer tanks have the same input parameters as the single coil DHW tanks.
10. Additionally, you define in the Redirection Valve section, the switching temperature for switching the three-way valve in the heating return.

The required values differ depending on the intended use of the tank.
