Heat demand relay

When the appropriately defined output terminal closes, a heat demand signal
is transmitted to the heat source.
Specify if a heat demand relay is used and how it is controlled.

Q1 (local)
Heat demand DC 0..10 V
The current heat demand can be transmitted to the heat source in the form of
a DC 0..10 V signal.
The temperature values corresponding to DC 0 V and 10 V and the threshold
value for a valid heat request can be set (see page 119).
Specify if the DC 0..10 V heat demand output is used and how it is controlled.

Refrigeration demand relay

When the appropriately defined output terminal closes, a refrigeration demand
signal is transmitted to the refrigeration source.
