Processing an external demand

An external set point can be transferred using this function. The set point can be transferred over
Modbus and/or over an analog signal at UE2.
The external demand works according to the maximum principle: If the internal set point is
larger than the transferred external set point, then the internal set point has priority.

Note:
– The external demand and the external demand for DHW share the input UE2. An analog
signal is used for external demand and is switched to the flow temperature set point for
the external demand for DHW when a binary signal is applied. Refer to section 6.3.
– The External demand (0V) and External demand (10V) parameters are available in firm-
ware version 1.50 and higher. In the previous firmware versions, the range is fixed to
0 to 10 V which corresponds to 0 to 120 °C.
