NOTE: If the communication settings have been changed, they are activated upon exiting the Maintenance Mode - the device
carries out a soft reset. Alternatively, power cycle will activate the new communication settings
Parameter Storage
The configuration parameters are stored in the non-volatile memory. When the changes are carried out via the display, the parameters
are stored in the non- volatile memory when the controller returns to a normal display mode. If the changes are carried out over the
network (Modbus or BACnet), then "NonVol Update" register/object is required to be forced on to save the changes. The register will
automatically return to normal state when using Modbus. In BACnet the object needs to re-triggered.
Modbus Registers
The controller supports the following Modbus registers and function codes. The default communication speed is 9600 bps, 8 data bits,
Parity None and 1 Stop Bit. The default Modbus Slave address is 1. The device Parity can be changed between Odd, None and Even.
The baud rate is selectable between 9600, 19200, 38400, 57600 and 76800 bps. The table shows the register offsets starting from 0 (0
Base) register address. For example, the Temperature is read from Modbus register 100 using Function Code 04. Some Modbus
masters will require one to be added to Modbus registers (i.e. 1 Base). In this case Function Code 04, register 101 needs to be entered.
