Functions & Settings

• Setpoint Setting
  Press “/\”or ” V” to set the desired indoor temperature. Setting range: 5~37 t (41~98 “F) by default.

• Mode Setting
  This device supports OFF, HEAT, COOL, AUTO mode and EM mode (not enabled by default). Press the “MODE” button to switch the working mode.

• Fan Mode Setting
  Short press the “FAN” key to switch the working mode of the fan.

• Fan On
  In this mode, the fan is always running when it is turned on, and stops when it is turned off.

• Fan Auto
  In this mode, the fan runs both in cooling and heating state ; the fan stops when cooling or heating is stopped, when the device is in shutdown state, the fan stops.

• Secret Menn
  Under “OFF” interface, long press “MODE” button for 3 sec to enter into parameter setting interface. Short press “MODE11 button to switch the parameter number, press A “or” V “to modify the corresponding setting value, and then press “FAN” to confirm and then exit.

Z-Wave Setting

1. Include into Z-Wave network
Under the normal working interface, long press” A “and” V ”button synchronously for 3sec, the device will enter Z-WAVE MENU interface, iflong press” A “and” V” button synchronously for 3sec again or without any operation for 10sec, it will back to the homepage. Before the device included into network,”- – -” will display on the screen. Then short press ” A” button, device will enter learning mode to get a node ID. If inclusion is success, a node ID will display on the screen in a few seconds. Note: A node ID can always inform us whether the device is in the network or not.
Exclude from Z-Wave network
Under the normal working interface, long press” A “and” V ”button synchronously for 3sec, the device will enter Z-WAVE MENU interface, iflong press” A “and” V” button synchronously for 3sec again or without any operation for 10sec, it will back to the homepage. Current ID displays on the screen, short press ” A” button, device will enter learning mode, current ID will flash, once “- – -” display on the screen, the device has excluded from Z-Wave network.
