10.1 Heat demand function
10.1.1 Purpose and enabling
The "Heat demand" function acquires heat demand from a heat distribution zone
via the bus. The collected heat requests can be routed to another zone or further
handled as a resulting setpoint condition (temperature request signal, heating flow
setpoint) as a continuous or digital signal.

To enable function "Heat demand", assign the load signal of a controller, enable the
primary controller or assign output Q, d, Y, a.

10.1.2 Use universal controller as consumer
Use "Extra configuration > Aggregates > Heat demand" at the corresponding
controller for a sequence of the controller to generate heat demand (see Section
10.3 for application examples).

This allows for generating a "Heat demand" signal that can be used by another
device on the KNX.
To do this, set a heat distribution zone.
