Before making any modifications to the profile opening contact Engineered Air.
INPUT CONTACTS BY OTHERS
Mechanical relay (dry) input contacts must be used. The use of solid state relay’s (SSR’s) may
cause the M-TRAC1 to malfunction due to reverse leakage current when ‘open’.
BMS SENSOR LOCATION
The Engineered Air sensor must be calibrated to match its operation with the Engineered Air
control. Do not calibrate it to match BMS readout if one exists.
If there is a BMS sensor located in the discharge duct, that sensor must be mounted within ½
inch of the Engineered Air sensor.
Note: BMS (Building Management System) discharge air temperatures should never be used to
reset the temperature of the heater. Only use space or room mounted sensors.
