IAQ1001 – IAQ Transmitter

Model : IAQ-1001



This full-featured CPU based thermostat is designed for small cooling and heating air handling systems in residential and commercial facilities. The unit provides features which eclipse standard mechanical thermostats at a price that fits conventional HVAC projects.

Special Features:
  • IAQ1001 with C02 sensor now available. All the powerful features of IAQ1001 zone controller plus a C02 sensor in one compact package.
  • Can be used as a stand alone zone controller for ‘demand based’ total solution
  • Or use the analog outputs as a regular C02 transmitter as inputs to a central controller
  • Modbus RS485 network connection for easy integration with automation systems
  • Tight control of 0.5°C provides comfortable indoor environment
  • High impact plastic enclosure provides durability in commercial environments.
  • Customizable sequence of operation table (FCU with modulating or on/off valve, single or 3-speed fan, pressure independent VAV, stage sequencer…)
  • An affordable CO2 sensing solution for HVAC/DCV
  • Dual Beam NDIR
  • Available in Clock, Clock & Humidity, CO2 ,OCC and Zigbee options
