The data link bus coupler DL-BC is able to read measurements over the data link of one control and make them available as a value to a second control via its data link. Transfer of
measurements takes place in both directions, i.e. also from the second to the first controller.
Moreover there is an option for connecting two temperature sensors (KTY or Pt1000) and
transferring the measurements over each of the two data links to the controllers.
The polarity of the connections ("earth") is interchangeable, hence is unimportant.
Intercommunication of measurements between 2 controllers via the data links
Minimum controller version:
ESR21, UVR61-3, UVR63-H: from version 5.0,
UVR1611: from version 3.0 and serial number 13286,
ESR31, UVR63, UVR16x2: all versions
Connection option for two additional sensors KTY or PT1000
Additional connection of two different controls of types ESR21, ESR31, UVR613, UVR63, UVR63-H, UVR1611 and UVR16x2 (observe minimum versions!)

At any one time, only one DL bus coupler may be connected to a controller.
Bus load:
when connecting to 2 controls: 14 %
upon connection to only one control: 19 %
Addressing
The requests of the two controllers are sent to the Address of the DL bus coupler together
with the Index of the measurement saved or captured there.
The Address is specified by disconnecting the conductors on the PCB of the DL bus coupler.
The conductors are labelled with numbers 1, 2 and 4 and are located on the rear side on the
board on the outer edges next to the screw terminals. An independent address can be specified for each of the two data links. If none of the conductors are cut, the PCB is assigned address 1 for both data links (factory setting). As long as no other sensors, allocated address 1,
2 or 3, are connected to the DL bus in question, then it is not necessary to change the address.
The effective address is derived from address 1 (= factory setting) plus the sum of all the values of disconnected conductors.
Example: required address 6 = 1 (factory setting) + 1 + 4
= conductors 1 and 4 must be cut.
Conductors on the rear side of the circuit board for specification of the sensor addresses:
Disconnectable conductors
(Controller 1)
Disconnectable conductors
(Controller 2)
The index can only be between 1 and 8. However, the data frames of UVR1611 and
UVR16x2 contain 16 sensor values. Together with the two temperature sensors (KTY,
PT1000 = 4 possible values) this gives up to 20 values. Therefore the indices of the measurements are divided over 3 addresses (set address A, address A+1, address A+2).
Measurements from the simpler controls (e.g. ESR21) require less index positions, the remaining indices then no longer yield useful measurements.
ESR21, ESR31, UVR61-3, UVR63 and UVR63-H: If the bus coupler is allocated an address
of higher than 6, then sensor values, which have an address higher than 8, cannot be queried, because "external sensors" can only be allocated up to address 8 in these controllers.
The controllers UVR16x2 and UVR1611 can also query sensor values with higher addresses.
The following data are allocated to the index and address:

ESR21, ESR31, UVR61-3, UVR63, UVR63-H: The desired measurements are imported as
"External sensors" (setting in the menu "EXT DL"), where address and index are specified
Example:
Here, the external sensor E2 was allocated the sensor value
of Address 2 with Index 1,
i.e. the sensor value 5 of the other controller (in the example:
UVR61-3 or UVR1611)
UVR16x2: The measured values are parameterised in the menu "DL bus“.
UVR1611: The measurements are parameterised as analog network inputs:
Network nodes:
Address of the desired sensor range of the DL bus coupler
(above example: 2)
analog NW output:
Index of the desired sensor value (above example: 1)
