Johnson Set-Point
4.1 Adjust DSP CAL until the SPC voltage reading matches the dial set point value divided by 10° will give VDC. Return
the dipswitches to their normal position.
Built In Set-Point
4.2 Loosen the setscrew on the set-point knob and move the knob until the dial set point agrees with the measured
set-point value. Tighten the setscrew and return the dipswitches to their normal position.
Room Sensor Calibration
1. Measure the room or return air temperature and set the room set-point dial to the measured value.
2. Record the settings of dipswitches 1, 2, and 3. Turn off dipswitches 1, 2, and 3.
3. Measure the G-TRAC2 calculated set point. (DC voltage from spade connector terminals “DTEMP” to “COMMON”.)
4. Turn dip switch 3 on.
5. Measure the G-TRAC2 calculated set point DC voltage again. Adjust the ROOM CAL pot until the “SPC” to “COMMON”
voltage is the same as was measured in step C.
6. Return the dipswitches to their normal position.
BMS Calibration and Set Up
Refer to notes for BMS (Section XVII, page 23).
