Ambient condition Value
Relative humidity 85% max. (non-condensing)
Ambient temperature -10 °C to +70 °C
1. Store the device in dry conditions, if possible in its original packaging.
2. Store the device in a dry room in which the atmospheric humidity is maintained
at a constant level (as far as this is possible).
3. Prevent excessive fluctuations in atmospheric humidity.

3 Description
3.1 Compatibility
The BACnet PICO Modbus gateway is used to integrate Calio pumps in the BACnet
MS/TP network. Communication with the BACnet MS/TP gateway takes place via the
Modbus interface (COM) at the pump. Do not change the default Modbus settings of
the pump.
The gateway can only be used as a master on the BACnet MS/TP network.
NOTE
Only one Calio pump can be connected via each BACnet MS/TP gateway.
3.2 General description
The device is configured with the following settings at delivery:
Device ID 247000 + gateway serial number
Master node address 1
MS/TP baud rate 38400
The default device ID of the gateway used to identify the device on the BACnet
network is created based on the sum total of 247000 (fixed value) and the last 3
digits of the device’s serial number.
Example: 247000 + SN1220M0010 = 247010
The serial number is located on the side of the housing.
The device ID can be changed during operation via BACnet.
NOTE
The master node address (HW address) must be set differently for all devices on the
BACnet network.
The master node address can be set using DIP switches. (ðSection3.3.2,Page8)
3.3 Commissioning
The MS/TP baud rate and master node address are set via a DIL switch on the printed
circuit board. Open the housing to change the baud rate or master note address.
Remove the printed circuit board.

3.3.1 Setting jumpers
Only jumper 1 (BACnet MS/TP bus terminator) typically must be set, if required,
during commissioning.
3.3.2 DIL switch
Fig.3: DIL switch 4
DIP switches 1 to 7 code the master node address, and DIP switches 8 to 10 code the
baud rate in the BACnet MS/TP network.
The values are binary coded from right to left.

010000032
100000064
The master node address can be set from 1 to 127 using the DIP switches. It may be
necessary to activate several switches to obtain the required address.
NOTE
Master node address 0 is invalid and deletes the current configuration on the
gateway.

1 0 0 56700
1 0 1 76800
1 1 0 115200
1 1 1 230400
The baud rate for the BACnet MS/TP network is set to 38400 by default.
3.3.3 Back-up battery
Insert battery of type CR2032 with the positive terminal pointing upwards. The
battery buffers the data and the real-time clock of the gateway during a power
interruption.

CAUTION
Operation without back-up battery
System malfunction!
▷Never operate the device without a back-up battery.
3.3.4 Error code
In the event of a malfunction, the red LED indicates the respective operating
condition. If no malfunctions are present, the red LED illuminates continuously.
Otherwise, there are 3 fault statuses that are displayed with the following flash
codes:
Approx. 1 - 3 sec.
No communication with BACnet
Modbus fault (exception, timeout, broken line)
Gateway without valid configuration
When Modbus communication between the gateway and pump is interrupted, the
gateway automatically attempts to re-establish the connection every 3 minutes.

All describable properties (see PICs) with the exception of PresentValue are
permanently saved in the gateway’s flash memory.
To ensure that values are written to the pump as required, PRG-1 P-Basic Program
must display the value “Running”.
AV-1 Calio_Setpoint, BV-1 Calio_Start/Stop and MV-1 Calio_OpMode can only write
values to the pump if Modbus is activated at the pump.
The gateway checks this periodically every 3 minutes.
