• Programming Mode

Step 1. Press and hold Down (-) button for 3 seconds to enter programming mode.

Step 2. There are 3 functions available for programming, including Thermostat Functions, Controlling Remote Relay, and Setpoint Offset. You can press either UP (+) or Down (-) button to switch modes.

Step 3. After finishing selection, wait for a few seconds for the Thermostat to enter selected mode.

Thermostat Functions (Heating and Cooling):

In this mode, “Pro Mod” will be displayed on the LCD screen.

Heating/Cooling modes are available for selection. Press UP (+) button to select Heating and Down (-) button to select Cooling.

Heating Cooling

After finishing selection, wait for a few seconds for the Thermostat to quit setting mode automatically. The Thermostat will enter the mode last selected.

Controlling Remote Relay:

In this mode, “Pro RM” will be displayed on the LCD screen. The Remote Mode allows you to control remote relay via the Control Panel when function enabled. The Thermostat will not control the local relay in Remote Mode.

• If remote mode is disabled, “dS RM” will be displayed on the LCD screen.

• If remote mode is enabled, “En RM” will be displayed on the LCD screen.

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.

Due to the fundamental structure of ZigBee network, ZigBee device will actively seek and join network after powering on. Since performing a task in connecting network may consume some power, it is required to follow the instructions to avoid draining battery of a ZigBee device

• Ensure your ZigBee network router or coordinator is powered on before inserting battery into the ZigBee device.

• Ensure the ZigBee network router or coordinator is powered on and within range while a ZigBee device is in use.

• Do not remove a ZigBee device from the ZigBee network router or coordinator without removing the battery from a ZigBee device.
