Mounting and installation 3 3 Mounting and installation Mounting NOTICE We recommend hiring licensed installers to mount and install the thermostat. ● ● ● ● ● ● Installing your thermostat The thermostat is suitable for wall mounting. The recommended height is 1.50 m above the floor. Do not mount the thermostat in recesses, shelves, behind curtains or doors, or above or near heat sources. Avoid direct solar radiation and drafts.
3 Mounting and installation 4. Disconnect all the labeled wires and then remove your old thermostat. NOTICE! Do not dispose of your old thermostat as part of household if it contains mercury in a sealed tube. Contact a thermostat recycling organization, for example, www.thermostat-recycle.org, for safe disposal of your old thermostat. 5. Check whether you need to have more wires connected to the power unit to be installed. If so, prepare the wires and label them accordingly.
Mounting and installation 3 9. Screw the power unit on the mounting plate tightly. 10. Attach the front module horizontally. Ensure that each side of the front module aligns with the power unit and press the corners in the order illustrated below: Top (1); bottom (2) until each corner clicks in place. Note: You must discharge static electricity from your body before mounting the front module. For example, touching the wall can help discharge static electricity. 11.

Appendices Frequently asked questions 11 11 Appendices 11.1 Frequently asked questions 11.1.1 What should I do if I forget the screen lock code? Try using the administrator password to unlock the screen. Unlock the screen using the administrator password 1. On the hardware unit screen indicating that the screen lock code is incorrect, tap the question mark > Login. 2. Input the administrator password, and then tap OK. 11.1.
11 Appendices Frequently asked questions 11.1.5 What is the difference between Administrated WLAN and Private WLAN? Administrated WLAN * is supposed to connect to an infrastructure network managed by facility managers; Private WLAN fits for owner cases and is supposed to connect to a home network. Selecting the WLAN connection type differently only affects the entry to WLAN management: ● If you’ve selected Administrated WLAN *, you can only manage WLAN under Advanced Settings.
Appendices Frequently asked questions 11.1.10 11 Can the thermostat display the time correctly if there is no WLAN connection? If there is no WLAN connection, the thermostat displays the time correctly only when: ● The thermostat connected to a WLAN network once and could display time correctly. ● The thermostat hasn't been powered off for more than three minutes. Lacking either of the above conditions may result in incorrect time display. 11.1.11 Can I set the time manually? No, you can’t.
11 Appendices Frequently asked questions 11.1.17 Can I create more than one user account in the mobile app? Yes, you can, but you cannot log into different accounts at the same time. Besides, it is normally unnecessary to do so if you want to manage more than one thermostat using the app, because one user account can associate with a maximum of 12 thermostats. However, one thermostat can only be associated with one user account.
Appendices Technical specifications 11 Self-heating compensation for relay can be affected by changes to the load current of the relay. But the device self-heating compensation cannot be directly influenced by user. 11.1.24 How does the thermostat adapt start optimization of outside temperature? The outside temperature is not involved with logical operation. 11.1.
