On/Off OperationWhen power is on, the device displays “OFF”, all outputs are forced off. Touch the S3 button to switch (manual/off/auto) mode, then press S2 to confirm and proceed with the power on/offsetting. After power on, the device displays the current week, local time, working mode, current temperature, output status, etc.
Note: After the backlit goes out, please press the button to light up the backlit first, and then press the button again for the corresponding operation.
Temperature SettingIn normal working status, pressing the S4 or S5 button will enter into the temperature setting interface. The setting range is 5-37 C (41-99F). Then press S4 or S5 can adjust the value. Press S3 or wait 25 seconds without any key the operation will save the setting and return back to the normal operation interface.
Auto Mode: The changed value is only valid in the current time period for this time, and the device will not affect the preset time period value.Manual Mode: The changed value will be valid until the next setting.Vacation Mode: The changed value will be valid until the next setting.
Key Lock FunctionIn normal operating interface, long press SI +S4 button, ft-icon appears that indicates the button is locked, at this time all buttons are disabled; When long press SI +S4 button again, icon disappear that indicates the button is unlocked, all buttons back to normal work.
MHTH-WH► Detection temperature < setting temperature – 0.5C, output turns on, and output icon displays.►Detection temperature setting temperature + 0.5 C, output turns off, and output icon disappears.
MHTH-EH► Detection temperature < setting temperature – 1.5C, output turns on, and output icon displays.► Detection temperature?: setting temperature, output turns off, and output icon
Manual / Auto Mode SettingIn a normal display interface, the touch SJ button can switch between Manual and Auto mode. Choose the mode you may need and press the S2 button to save the setting.Auto Mode: Device will follow the preset time periods and temperature to control the heating system automatically.Manual Mode: Device will follow the manual setting temperature to control the heating system.
Vacation Mode SettingIn normal working interface, if vocation mode is not activated, long-press S2 button to enter vacation mode temperature setting. The default temperature is 10 C, and the setting range is 5.37 C (41-98 F). Press S4 or S5 to adjust the value, then press S3 or wait 25 seconds to save the setting and return to the normal working interface. In this time vacation mode icon displays and the device will follow the setting. Long press S2 again will end vacation mode and resume to normal work, vacation mode icon will be disappeared.
Local Time SettingIn a normal working interface, long press SI to enter into local time setting interface.
In the local time setting interface, press S4 or S5 button to set the “week, hour & minute” parameter, and press the SI button can switch among the “week, hour & minute”.After finish, the local time setting, press SI or wait 25 seconds without any key operation will save the setting and return to the normal display.
Auto Mode Time Periods Parameter SettingIn a normal working interface, short press SI to enter into time periods set. Four-time periods can be set for each day of the whole week.Press S2 can switch among “Hours, Minutes, Temperature value”. Press S4 or S5 can change thevalue.After finishing the setting of 4 time periods on Monday, press S 1 and follow the same way to set periods of the next days.After all, periods are set, press S 1 /S2 or wait 25 seconds without any key operation will save the setting and return to the normal display. The device will operate in accordance with the new setting.
The default setting is as follow:
|Period 1||Period 2||Period 3||
|Mon—Fri||5:00||28 C||7:00||24 C||17:00||28 ‘C||22:00||24 C|

High-Temperature Protection (For MH7H-EH Electrical Heating ONLY)When the external temperature sensor detects the temperature value>55 C, the device will open high- emperature protection, electric heating will be forced off, and the high-temperature protection icon displays.When the external temperature sensor detects the temperature value< 50 C, the device will return to normal work, high-temperature protection icon disappears.
Anti-Freeze Protection Function: (Optional)
In shutdown interface:When the built-in temperature sensor detects the temperature value<5C, the device will open anti-freeze protection, electric heating will be forced open, and the anti-freeze protection icon displays.When the built-in temperature sensor detects the temperature value> 8C, the device will turn off anti-freeze protection and return to normal work, the anti-freeze icon disappears.Note: If the device does not connect with an external temperature sensor, it will only display the indoor temperature icon; If the device connects with an external temperature sensor, it will display the indoor temperature and high-temperature protection icon; When it is under high-temperature protection, high-temperature protection icon flickers.
Humidity Display OperationIn normal working interface, long press SI +S5 buttons and enter into humidity display interface when press SI +S5 buttons again, it will back to the normal interface.
• Including & Excluding of Z-Wave network
In a normal working interface, press & hold S4 to enter interface for inclusion or exclusion of-Wave network. Before the device is included in the network,”– will display on the screen. Then press S4 once, the device will enter learning mode to get a node ID. If inclusion is successful, a node ID will display on the screen in a few secondsA node ID can always inform us whether the device is in the network or not.
Note: Follow the same steps to exclude the device from the network. When removed, the device will restore its Z-Wave factory setting.After inclusion, tum off the device and then tum it on. Now the device is ready to be operated by controller/ gateway in the Z-Wave network.
