Description
Reload Default Settings
Software Version
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
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
0 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.
