Welcome to the product support page for Controller devices. This collection includes user documentation for a wide variety of control modules used in home automation, HVAC systems, and industrial applications.

Whether you are looking for programming instructions for the XY-WTH1 Temperature and Humidity Controller or installation guides for remote PIR fan timers, this library provides the technical specifications and wiring diagrams needed for setup and maintenance. These resources cover generic and specialty controllers designed to regulate power, environment, and motion.

• How do I reset my temperature and humidity controller?

  Reset procedures vary by model. For many digital controllers like the XY-WTH1, a factory reset can often be initiated by holding specific button combinations (such as Up and Down together) for several seconds. Always refer to the specific user manual for the correct key press sequence.

• Where can I find wiring diagrams for my controller?

  Wiring diagrams are typically included in the installation section of the user manual. For the products listed here, such as PIR or temperature controllers, check the downloadable PDF for schematics regarding input power, load connections, and sensor placement.

• What does the 'H' or 'C' mode mean on my temperature controller?

  On many generic temperature controllers, 'H' stands for Heating mode (activates when temperature drops below setpoint) and 'C' stands for Cooling mode (activates when temperature rises above setpoint).
