Description Notice Because of the Ruian postal policy,Ruian buyers please write your full name in the shipping information Product introduction New Air intelligent controller (KF-800F) can monitor real-time indoor temperature, CO2 concentration. Controller output signal can directly control the startup and speed of fan. It can be widely used in residential, commercial and industrial applications, and can effectively improve air quality, create a healthy, comfortable, energy-efficient living and working environment. FeatureManual or timing Set the fan operationOutput control 3 speed fanSuitable for different fans (2 lines, 3 lines, 4 lines)Indoor CO2 monitoring control outputDifferent CO2 concentration, different background lightsRS485 controlAlso can measure the current temperatureTime displayLarge LCD screen with bright backlight, work to use.Suitable for house, shopping mall, bus station and indoor other places.Embedded 86 box installed And mounting box optional Product Parameter* CO2 display range: 350ppm-3000ppm* CO2 adjustment range: 350ppm-1500ppm* Dimension::868640mm* Warm-up time: 1 minute* Fixing hole distance: 60mm(standard) * Response time: 10 seconds* Wiring terminal: Max 2.5 mm2 wire * Recovery time: 30 seconds * Rated voltage: AC220V 50Hz * Operating temperature: -10 c +50 c* Standby Power: 0.5W * Operating humidity: 5% RH- 90% RH* Control power: 200W * Storage temperature: -10 c- +60 c * Output interface: Three-speed ventilator * Storage humidity: 60% RH* Temperature display range: 0-50 c * Life: 10 year Item Display Wiring Diagram Project Installed Item Picture Note:1, When the ambient CO2 concentration is le than 350PPM, the controller shows 350PPM, because CO2 display range: 350ppm-3000ppm;2,If you first use the controller,CO2 sensor to warm up about 1 hour,Screen CO2 reading approach the correct value.3,If the controller screen CO2 concentration reading remains 350PPM, you blow the sensor to verify the controller.
