**Setpoint Offset:**

In this mode, “Pro OFS” will be displayed on the LCD screen. Setpoint Offset function allows you to compensate the deviation. To calculate setpoint offset, simply subtract room temperature with device temperature. When under local mode, press and hold Down (-) button for 3 seconds to enter programming mode. After finishing selection, wait for a few seconds for the Thermostat to enter mode selection.

For example: If device temperature is 20°C and room temperature is 18°C, then setpoint offset = 18 – 20 = -2°C.

After setpoint offset is applied, the device will operate according to adjusted temperature.

For example: If device temperature reading is 20°C, setpoint offset is -2°C, the device will operate using 18°C as actual reference.

## **ZigBee Network Setup**

* _**ZigBee Device Guideline**_

ZigBee is a wireless communication protocol that is reliable and has low power consumption and high transmission efficiency. Based on IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a network and coordinated for data exchange and signal transmission.
