Setting the standard heating load
The standard heating load is obtained by multiplying the specific heating load by the living area to be heated.
You can calculate the standard heating load from the following table.
This method is only estimated and should be set to the values defined by an expert.

Selecting the pump system
Select the pump system for the speed controller. The speed control system is available for a solar cycle with
asynchronous pump (controlled by an A01 with "wave packets"), as well as for one or two solar cycles with
high-efficiency pump (controlled by an A01 with "PWM").
We recommend activating an EC pump. The solar pump adapts automatically to solar capacity. If the tem-
perature difference increases due to increased solar capacity, the speed of the solar pump is increased.
(This results in a higher degree of efficiency of the solar plant as well as lower power consumption of the
solar pump).
