11.3 GENERIC HEAT DEMAND
A generic heat demand does not come from one of the three available heating circuits and/or from the DHW circuit. This type of
demand is called user demand and is used to provide heat to external units such as heating water in a swimming pool.
To enable this function, perform the following configuration procedure. Enter menu 2 from the Remote Control, as described in
section 5:

USER CR1
If the user demand is provided via a 0-10 V analogue signal, set parameter 6046 to "User demand CR1 10V". Also set signal
characteristics using the following parameters:
