Contractor level parameters
Parameter HG34 enables the selection of three types of eBUS
feed.
The settings have the following meaning:
0 → eBUS feed switched OFF
1 → eBUS feed switched ON
2 → automatic eBUS feed
Parameter HG35 enables a switching of the 0 - 5 V input for a
telecontrol system.
The settings have the following meaning:
0 → Outside temperature sensor connection
During commissioning the control unit checks whether and where
an outside temperature sensor is connected.
1 → 0 - 5 V input (no outside temperature sensor connected)
The voltage signal at the 0 - 5 V input is used as control variable for
defaulting the set header boiler water temperature (independent of
the setting of the programming selector at the BM).
Limiting the set fl ow temperature by TV
The boiler circuit pump becomes the feed pump.
Pump ON with burner demand.
Pump run-on in accordance with parameter HG07.
Depending on the transfer function (see diagram), the set temperature
is calculated subject to the input voltage.

Note:
Prior to connecting the telecontrol system, set parameter HG35 to 1. Set
system parameter A06 (setting the external sensor) to "0". Switch off the
mains power, connect the telecontrol system to plug "AF". Switch the
mains power ON again. Otherwise an outside temperature sensor could
already be detected at low voltage → FC 15.
