The pulses for the amount of heat flowing through are counted, e.g. 5 pulses within a minute. Through calibration via parameter 12, the actual thermal output in kW is calculated.

7.2.14Charging pump (CHP)

NOTE This function is only active if the charging pump function was assigned to one of the outputs "direct heating circuit pump", "variable output 1"or "variable output 2" in the "Hydraulics" menu.

Function A charging pump to supply remote parts of the heating system is active at every heating or hot-water demand to the heat generator. It can be connected, through variable settings, at one of the variable outputs or at the direct circuit pump output.

Bus system A charging pump connected to the central device under address 10 will run as soon as any demand is present on the data bus (including all heating and hot-water circuits within the control network).

A charging pump connected to an extension controller (address 20, 30 ... 50) runs only on demand from the heating circuit associated with the respective control device.

Charging pump To avoid a high-temperature safety switch-off of the heat extended running time generator, a charging pump is switched off according to the set

time delay when a request to the heat generator is withdrawn.
