Application The Fantech Exhaust Makeup Air System is a low voltage controlled assembly of components which provides the automatic supply of outdoor air into a building. When controlled by the current sensing Fantech Makeup Air Controller “FMAC”, the system is suitable as compensation for single speed, multi-speed, and variable speed exhaust fans.

Makeup Air System Installation Read all instructions before starting installation. Low voltage wiring should be routed the shortest distance possible to avoid unnecessary voltage drop. The current transducer wire shall be a minimum 20 AWG twisted pair. The current transducer and all control wires shall be kept away from high voltage wiring to avoid signal interference. Recommended ambient operating temperature range for the makeup air system is -20oF (28.8oC) to 140oF (60oC).
Makeup Air Controller and System Startup: Prior to beginning the setup and startup procedure, verify that the makeup air system is completely installed and wired, and verify that the compensated exhaust system is completely installed and wired. a. Install a clean panel filter into the makeup air system’s filter cassette. b. Energize the power circuits to; • Makeup air fan. • Transformer. A power indicator and heart pulse LED will illuminate when the FMAC is energized and ready for programming.
Controller Operation and System Wiring When the FMAC's controller receives a signal from the current transducer that the compensated exhaust fan is operating, the FMAC controller's outputs will be activated. The controller will provide a 24VAC signal to power the motorized damper to the open position. The controller will provide a 0-10VDC signal to the makeup air supply fan to operate the fan at a speed proportional to the compensated exhaust fan's speed.

Notes All wiring is by others. Wiring terminations for each component are contained in their respective installation instructions. Placement of components is up to the discretion of the installing contractor. For applications with small current loads (such as less than 2 Amps), wrap the monitored conductor through the sensor aperture several times to increase the current measured by the sensor. Example: Exhaust fan amperage rating of 2 amps. One pass through the CS650-10 aperture V output is approx.
