2 MT2325A Chore-Tronics 2® 12 Volt Wiring The Relative Humidity Sensor requires a three-conductor wire to connect the sensor to the Chore-Tronics 2 control. The sensor can be wired to any analog in terminal on the I/O board. The sensor can be supplied by 12 or 24 Vdc. (See Figure 2) Chore-Tronics 2® 24 Volt Wiring An AI terminal on the I/O board terminal block is wired to the #2 terminal on the relative humidity sensor quick connector Part B terminal block. The ground terminal next to the AI terminal is wired to the #3 and 12 or 24 Vdc is be wired to the #1 terminal.
