Wiring Diagram & Display Functions
Functions
Power On/Off
Power ON: Under OFF interface, long press S2 key to power it up,
thermostat enter in normal working interface. Power OFF: Under normal
working interface, long press S2 button to power it off, all output forced
OFF.
Temperature Setting
Under normal working interface, press Si or S3 to modify the setting
temperature, then press S2 as confirm or after 5sec without any operation, it
will back to the normal working interface. The temperature setting range is
5-37 C.
S2 Key Function
-
Z-wave network state: Under normal working interface, press S2 key to enter in Z-wave network state interface, if shows mean the device is included in the network if shows means the device is not included in the network. Press S2 to switch to the next item or press 81/83 to back to the normal working interface.
Note: If the device is not with Z-wave function, then the above interface will not display. -
Output state: Under normal working interface, press S2 twice to enter in the output state interface, if shows mean output state is ON if shows means output state is OFF, press S2 to switch to the next item or press S1/83 to back to the normal working interface.
Note: If the device is not with Z-wave function, then the above interface will not display. -
Mode selection: Under normal working interface, press S2 three times to enter into Mode Selection interface, press Si or S3 to select mode. Interface shows means it is in Manual Mode, shows means Energy Saving mode. After setting, press S2 to switch to the next item, or after 5sec without any operation, it will back to the normal working interface.
-
LED Standby brightness setting: Under normal working interface, press S2 four times to enter into LEDstandby brightness setting interface, press SI or S3 to modify the brightness, there are 3 brightness levels that can be set (All dark: Semi-bright: Full bright: ) After setting, press S2 to switch to the next item or after 5sec without any operation, it will back to the normal working interface.
Mode Setting
Manual mode: The device controls the room temperature manual.
Room temperature ≤etting temperature+ 1 C, Output ON;
Room temperature≤Setting temperature – I C, Output OFF
Energy – Saving mode:
Normal working interface display and indoor temperature. Press S1/S3 can
set the device opening time, 20min for a period, set range: I-20min.
Note: This mode will not follow the setting temperature and the difference of indoor temperature to turn ON/OFF the device.
Z-Wave Operation
Including & Excluding of Z-Wave network
Under normal working interface, long press S l+S3 to enter in Z-wave Inclusion/Exclusion interface, the interface shows the current Node ID (If shows”- – -“then means the device is not included in the network) a Short press S2, the device enter into learning mode, after learning mode is completed, the device shows Node ID (. Note: According to Node ID display state, we can learn whether the device is included into Z-Wave network or not)
During the Z-wave network learning period, long-press SI+S3, it will force to
quit the Z-Wave learning state, then back to the normal working interface.
Under the Z-wave setting interface, if the device is not entering in learning
state, the z-wave Node ID will not blink, press SI or S3 back to the normal
working interface.
