detailed information about "MODBUS".
5.9.1 Addressing member MODBUS Master Interface
Up to 32 members can be connected at the MODBUS Master interface.
No other components are required for the patented automatic addressing (activation
menu group
MODBUS Master: AutoAddressing). Only the connections “ID1” and “ID2” of the Slave members are
connected additionally next to the bus connection and at the “ID” connection of the MODBUS Master
for this.
The “ID” connection of the MODBUS Master must be connected to the “ID1” or “ID2” connection of the
first Slave member. This is recognised as a result and occupied by address 1.
For the following users the connection “ID1” or “ID2” of a Slave user respectively is connected with
connection “ID1” or “ID2” of the next Slave user.
The automatic addressing of other users is initiated by the previous user via this connection.
The individual members can be addressed in advance without this device by an external terminal or a
PC.
Alternatively, the addressing can be done manually by a separate hand held terminal or PC software,
the appropriate number of members must then be entered on the MODBUS Master (
menu group
MODBUS Master: BUS Slavecount).
Information
•When using the automatic addressing, no repeaters can be used because these do not pass the
signal through to the addressing.
•Depending on the version, the connections for MODBUS “A (D+)”, “B (D-)” are available single or
double at the Slave members. These are connected with each other internally electrically.
•The connections for the automatic addressing “ID1” and “ID2” are not directly connected with each
other internally. These may not be bridged; any order of connection is possible.
•Do not connect the cable screen! When using the connection box, the cable screen of the CAT5
cable is connected internally by an RC element to “PE”.
•The communication parameters are fixed

* Detailed description
IO Setup / Digital Inputs “D1” / “D2”
Following restrictions apply for the control circuit 2:
•The “Manual Mode” function in the “Setting” menu group only influences control circuit 1!
•The Limit (
IO Setup | 3D | and Controller Setup) function influences both control circuits simulta-
neously.
•The “Max. Speed” setting by a digital input (
IO Setup | 11D | ) simultaneously influences both
control circuits. I.e. at “1.Max. Speed” and at “2.Max. Speed”.
•The controller configurations (KP, KI, KD, TI
Controller Setup) are identical for both control
circuits. Fine adjustment is possible for each control circuit by the separate “Pband” setting.
6.3 External Setpoint / External speed setting in manual operation
External setpoint setting or external manual operation are possible using a 0 - 10 V (0 - 20 mA, 4 - 20 mA) signal
at the “E2” and “GND” terminals. Configure “E2” in Base setup. For potentiometers, program Analog Out 1
(terminal “A1”) to the function
| 1A | “+10 V” (as factory setting IO Setup).

External Setpoint via external signal instead of “Setpoint 1”. The “external Setpoint” function must be activated
in base setup
| 1E | for “E3 function”. The active external Setpoint value is displayed in the “info” menu group.
External speed setting in manual operation. The “external manual operation” function must be activated in the
basic settings
| 2E | for “E3 function”. Switchover between settings on the device and external manual operation
via the digital input (
IO Setup: “Control / manual operation” | 7D | ).
Not possible in modes with 2 sensors and operation with a second control circuit because the second
analogue input is already occupied by it.

An outside temperature compensation can be activated (sensor connection “E2” “Analog In 2”) when being
operated as a pressure regulation device.
An optimal building climate, e.g., can be achieved through this. Through this function, the set and active
“Setpoint1” or “Setpoint2” is automatically changed proportional to the measured outside temperature (
