The settings for input H2 on the extension module correspond to a large extent to
those for the Hx inputs on the controller (without Pulse count, Flow measurement
Hz). For descriptions, refer to operating line "Function input H1, H3" and following.

7318 7393 7468
Defines the temperature acquired by the sensor connected to "Input H2 module
1....3" (solar flow/return or heat pump flow/return). The controller uses the acquired
temperature to control the respective plant component.
If, for temperature acquisition, the same sensor is defined at Bx and Hx, the sensor
connected to Bx is given priority.
