To activate Test Mode, press the UP and DOWN buttons for 3 seconds while in the Main Menu. A notification will
be shown that the unit has gone into Test Mode. This notification is only displayed for a few seconds.
The set point / settings modification feature can be Locked / Unlocked from Modbus or from the Display itself.
Locking or Unlocking the set point / setting modification can be done with the following sequence:
MENU - UP - SET - DOWN – MENU
This sequence can be executed only when in the main menu (TEMP READINGS / TEMP SETPOINTS screen). Each

RS 485 Modbus Interface
Modbus is a serial protocol used for communication between a Master and a number of Slave Devices. The
master requests information from the slaves by specifying the slave address, a read or write command and
which register address it will read from or write to. Modbus can read or write a single register or multiple
registers at the same time.
