Installation
The thermostat is applied to full load in areas with the altitude of less than 2500m above sea level. Power rating of external load should be less than or equal to 80% rated power of the thermostat in areas with altitude of 2500m to 4200m.
WARNING:
- Installation must be carried out by a qualified electrician.
- Before installation, please check conformity with local electric standards.
- Power supply must be turned off during installation and cleaning.
- Wipe the surface with a soft cloth or tissue; do not use detergents or corrosive chemical solutions.
- Use a standard wall box for proper installation.
- Do not connect L&N or LO&NO reversely.
- Protect the cover during installation to avoid damage.
- When connected to AC230V, the surface cover must be installed. All voltage parts should be considered as 230V.
