In high resolution mode, the temperature = (Modbus register value) ÷ 20. In low resolution mode, the temperature is (Modbus register
value) ÷ 2.
Temperature values are stored as signed values in the Modbus register. A 0 in the register is interpreted as 0°; and 65535 in the register
(0xFFFF) is interpreted as −1 ÷ 20 = −0.05° in high resolution mode and –1 ÷ 2 = –0.5° in low resolution mode.

Before making any changes to the DIP switch positions, disconnect
the power. For devices with batteries integrated into the housing,
remove the battery for at least one minute.
DIP switch changes will not be recognized if power isn't cycled to
the device.
