MH3901-Z is a smart boiler thermostat, it can automatically detect the indoor temperature and display the relevant temperature value for boiler heating control. It also can automatically turn on/off the heating system according to the temperature difference. The device can be remotely controlled by the Z-Wave network.
Power On/Off
Temperature Setting
Under normal working interface, press S1 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.
Temperature Deadband setting
Under normal working interface, long press SI to enter into temperature dead band setting. Press Si or S3 to modify the value of the temperature Deadband setting, then press S2 as confirming, or after 5sec without any operation, it will back to the normal working interface. The value of the temperature dead band setting is 1.5 C by default. The temperature Deadband setting range is 0.5-5 C.
Mode Setting
Manual mode: The device controls the room temperature manual.
Energy-Saving mode: Normal working interface display and indoor temperature. Press 81/S3 can set the device opening time, 20min for a period, set range: 1-20mino
Note: This mode will not follow the setting temperature and the difference in indoor temperature to turn ON/OFF the device.
Temperature Calibration Under shutdown state, long press the SI+53 button then enter the temperature calibration interface, press Si or S3 to switch the value, then press S2 to confirm the setting. The temperature calibration range is -9.9 C — +9.9 C, the default value is 0.
Including & Excluding of Z-Wave network
Under normal working interface, long press S11-53 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 S 1+53, 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.
