6.6 Consumer circuits and swimming pool
circuit
Other consumers, in addition to heating circuits HC1-HC3 and the
cooling circuit, can be connected or controlled (e.g. door heating,
swimming pools, etc.).
Q15/18/19
The controller can receive its temperature request via an Hx input
and control the corresponding pumps via a relay output QX.
For the consumer circuits, the following settings are available:
An appropriately defined Hx input on the device or extension module (line 5950,
5960 or 6046, 6054, 6062) required to use consumer circuits / swimming pool
circuit. The input can be defined as follows:
Cons request CC1, 2
Cons request 10V CC1, 2
Release swimming pool generation
Operating lines 5750 and 5751 are available to select whether the consumer
circuits are used for heating or cooling.
The pumps are to be connected to the appropriately defined multifunctional relay
outputs Qx.. (line 5890-5896 and 6030 - 6038).
The consumer circuit pumps (Q15 / Q18) are put into operation when there is a
heat or refrigeration request at the respective input, or when excess heat draw is
called for.
The swimming pool circuit (Q19) starts up when the release is pending at the
corresponding input Hx and the swimming pool temperature is below the setpoint
(line 2056).
