3.the operating instructions

Installation position

XW***0 temperature and humidity sensor can be installed indoor wall, ceiling ceiling installation.

wiring

The XW***0 temperature and humidity sensor is electrically connected to the outside through two RJ*5 connectors. The RJ*5 connector is used for power supply, communication, and device cascading. At the same time reserved the terminal, inconvenient to use the network cable can be connected through the terminal.

The XW***0 temperature and humidity sensor provides power supply and RS**5 output interface. When connecting, V+ is connected to the positive terminal of the power supply, V- is connected to the negative terminal of the power supply, D+ is connected to RS**5 positive, and D- is connected to RS**5 negative.

Precautions

a. During the installation, the terminal of the slot is connected to the sensor base, and the transition of the PVC terminal head is applied. In order to ensure that the slot and the sensor are installed on the same axis, it is recommended that the base be installed first and then in the slot.

b. The horizontal distance from the sensor to the air-conditioning air outlet should be greater than 1.5m, and the distance from the ceiling air-supply outlet should be greater than 0.5m.

Fourth, debugging

After all the wiring steps of the XW***0 temperature and humidity sensor are completed, the following instructions can be used for debugging.

MENU : Press to enter the setting interface and exit interface (quit).

â–³ : Setting mode: Turn up the function and increase the setting value;

â–½ : Setting mode: Flip down function and increase setting value

ENTER: Confirm the setting value.
