The HCs can be switched on or off
DHW pump off switch
Duration of the pump shutdown when
reversing the reversing valve between
heating and DHW operation.
If the parameter is set to 0 there is no
pump shutdown. In addition, working
with the delay in parameter 5733 must
be set to 0 seconds.
DHW pump off delay
Duration of delay in the course of the
valves change-over, when interlocking
between heating and DHW operation
(0 = no delay).
System pump Q8
Here you can set whether the system
pump Q8 is to support the heat
requirements of the whole zone or
only of HC1, HC2 or DHW (bits 0-3).

Programmable outputs
On the LMU, the K2 relay output or the
clip-in relay outputs 1-3 can be
programmed with the following
functions, as long as they are already
defined by a particular hydraulic
diagram as a function.
Relay output K2 LMU -
base, default K2 to K1
In some hydraulic diagrams the
programmable output K2 is assigned
to a basic function.
This basic function is set on the K1
output using this parameter.
This means that another
programmable function can be set
on the K2 output.
If the "Default K2 to K1" parameter is
set, the function of output K1 is
overwritten with the basic function of
the output K2.
