User manual

HK Instruments Indoor air quality transmitters Siro-MOD series are transmitters intended for use in building automation systems in the HVAC/R industry. They offer easy installation and adjustment, several model options, and various output signals configurable for each parameter. The Siro-MOD series can monitor and control indoor air quality in offices, public spaces, meeting rooms, and classrooms. They can also be used to regulate demand-controlled ventilation, assess the performance of air filters, and measure temperature and humidity in HVAC/R environments.
