Hysteresis has been built in to prevent the temperature setpoint from rapidly changing.
The setpoint offset will only operate correctly if the BMS Room Temperature is periodically updated via Modbus, to
ensure the MelcoRETAIL MINI always has an up to date reading.
If the BMS Room Temperature is set to 0ºC (which it will be on power up) the setpoint offset feature will be disabled. It
will only activate when the BMS Room Temperature is greater than 0ºC.
Note: To disable the feature without removing the MelcoRETAIL MINI power, simply set the BMS Room
Temperature to 0ºC via Modbus.
