2. Important Precautions
Please read the following precautions carefully before installation and operation to ensure safe and proper use of your thermostat.
- The thermostat currently supports 2.4GHz Wi-Fi networks only and does not support 5GHz networks. Ensure your router is configured accordingly.
- The thermostat's power board is designed as a wall panel and can be connected directly to a wall or installed within a standard electrical cassette.
3. System Types: Two-Pipe vs. Four-Pipe
Understanding your HVAC system type is crucial for proper installation and functionality.
Two-Pipe System
A two-pipe system utilizes a single set of pipes for both cooling and heating. While simpler in design, it cannot simultaneously provide both cooling and heating. The system operates in one mode at a time.
Four-Pipe System
A four-pipe system offers greater flexibility, allowing for simultaneous cooling and heating without the loss of efficiency from mixing hot and cold water. It features separate supply and return pipes for both cooling and heating, creating two independent systems for cold and hot return water.
