How to use
Install the regulator on a stable interior wall at a representative height for room conditions, avoiding direct sunlight and local heat sources. Connect the device to the control circuit according to the system wiring diagram provided by the system manufacturer or installer. Configure the connected controller or actuator to respond to the two-state outputs of the T-2.1 and monitor the displayed or read humidity data through the host system as applicable.

Usage recommendations
For accurate humidity readings and effective temperature control, place the regulator away from windows, doors and ventilation outlets. Use the wired connection to integrate the regulator with a compatible HVAC or control panel and follow local electrical safety codes during installation. Periodic visual inspection and cleaning of the housing will help maintain sensor accuracy.
