Positive supply for a remote set point POT. DIP switch settings are noted on the internal wiring diagram, and should not be altered. TABLE 2 DIP SW Description Disable Auto Heat Switch. Modifications to these should only be performed by experienced and qualified personnel. TABLE 4 Description SP LMT Limits the maximum discharge temperature set point. CAL DTEMP Discharge air sensor temperature calibration. The voltage reading relates to the actual temperature of the discharge sensor. Sensor accuracy is diminished at temperatures greater than those noted in this table. PROFILE PLATE VELOCITY The profile plate has been factory set for the airflow shown in the submittal record. TRAC1 will remain locked out, but only green LED flashing irregularly. Depends on type of damper actuator used. TRAC1 allows time for the dampers to open prior to starting the supply blower. TRAC1 uses output terminal SA to control the supply air fan. TRAC1 has a built in profile pressure sensor to prove and monitor air flow across the burner. This allows the burner to operate safely and efficiently by proving the airflow is within proper air velocity limits. TRAC1 OPERATION EXHAUST FAN INTERLOCKING There are a number of different exhaust interlocking options available. Always refer to the wiring diagram and unit function sheet to determine the exact type of interlocking used. TRAC1 is using the face mounted setpoint dial or an optional remote mounted setpoint dial. TRAC1 is using its built in setpoint dial. TRAC1 PROFILE VELOCITY Profile velocity test point readings outside the 4.
