Overview of the handover module
1
Operating condition and information.
A description of the operating conditions can be
found in the integrated Help menu by pressing the
button.
2
Current heat supplied (only visible when optional
heat meters installed)
3
Position of the district heating valve (100% = open)
4
Flow temperature of the secondary side
5
Heat transfer station consumer.
If the consumer is being charged (in this example
the hot water tank), a line appears, and the flow
temperature and the symbol of the consumer are
shown in yellow.
6
On/Off switch for the heat transfer station
= switched on
= switched off
Function
The heat is released from the primary side heat
producer (e.g.: district heating network) via the heat
exchanger to the secondary side consumer. The flow
from the heat producer to heat exchanger is regulated
with the district heating valve (primary valve), which
regulates the heat volume.
The consumers, for example a heating circuit and a hot
water tank, are supplied with heat from the separately
regulated pump and the changeover valve on the heat
transfer station.
The primary valve opens as soon as there is a demand
from the consumers. The secondary pump starts after
the set delay has expired and supplies the consumers
with heat. If there is no demand, the secondary pump
is shut down and the primary valve closes.
To protect the consumers, a maximum flow
temperature as well as a frost protection limit can be
set. Frost protection is also in effect if the module is
switched off with the On/Off switch

10.1.1.1
Serial no.
Explanation of [Serial no.]
With this parameter, the serial number of the M-bus
meter is entered. This is needed for identification of the
connected M-bus meter (heat flow meter as well as
electric meter), so that the function block can read the
corresponding data of the meter.
If in the serial number are letters, the serial
number must be rotated while entering. Details to
this can be found in the manual of heat flow meter.
example: 1234 0A5678 => 56781234
The [Service] access level is required to perform
modifications.
The parameter can be found under:
10.1.1.2
Read out interval
Explanation of [Read out interval]
The interval for reading out the data of the M-bus meter
is entered with this parameter.
Too short an interval can trigger an error
message on the M-bus meter. Refer to the M-bus
meter operating instructions for the shortest interval to
be set.
The [Service] access level is required to perform
modifications.
