Minimum flow temperature setpoint TVHw
The adjusted minimum flow temperature setpoint will be activated via terminals H1/2
(e.g. an air heater function for a warm air curtain) closes its contact.
Excess heat discharge
Active dissipation of excessive heat enables an external heat source to force
consumers (heating circuit, DHW storage tank, Hx pump) to draw excessive heat by
delivering a forced signal.
The parameter “Excessive heat draw“ can be used to determine for every consumer
whether or not it should take account of the "forced" signal, and hence whether or not
that consumer should participate in the dissipation of heat.
•
Local effect
When using LPB device address 0 or >1, excessive heat dissipation only acts on the
local consumers connected to the controller.
•
Central effect (LPB)
When using LPB device address = 1, excessive heat dissipation also acts on the
consumers connected to the other controllers in the same segment.
The distribution of excessive heat from segment 0 across other segments of the system
is not possible.
Release swimming pool
This function can be used to enable direct heating of the swimming pool via the
boiler and H… pump externally (e.g. with a manual switch)
For direct charging, a release signal is always required at the H.. input.
Configuration: Set the function of input H.. to "Release swimming pool" and select the
associated H.. pump at a QX output.
This function can be used to enable solar heating of the swimming pool externally
(e.g. with a manual switch) or to define solar charging priority over storage.
Configuration: Set the function of input H.. to "Release swimming pool". Refer to
operating line 2065 "Charging priority solar" for a description of the function.

Heating demand 10V
Heat generation receives heat requests in the form of voltage signals (DC 0...10V).
The flow temperature setpoint corresponding to the voltage level of 10 V can be
adjusted via parameter “Temperature value 10V H…“.
Pressure measurement 10V
The voltage signal present at input H.. converted to a pressure value in a linear
manner.
