A G-TRAC2 MANUAL
General Manual Revised: 03/15/99
XV. THE MASTER SET-POINT
As a set point, the G-TRAC2 is designed to use either:
• The set point mounted on the face of the G-TRAC2 (range of 12.7-37.8°C or 55-100°F). If the G-TRAC2 face
mounted set point is used, terminals ‘SP and S’ must be jumped, or;
• The Johnson TE 6100-960 set point (range of 50-85°F and usually remote mounted). If the TE 6100-960 is
used as a set point, ‘S to SP’ is not jumpered and the TE 6100 must be wired as follows:
TE 6100 Wires G-TRAC2 Terminals
Violet (not used, sensor)

Orange
S
Grey
U
Red (not used)
Q
(No jumper S-SP) P
XVI. INDUCED VOLTAGE ON REMOTE CONTROL WIRING
Factory calibration will satisfy most applications unless resistance from long wiring runs or induced voltage on the
remote wiring cause it to be out of calibration. (To check for induced voltages, disconnect all of the field wiring in
question from the G-TRAC2 while the unit is operating, and check for AC volts across each questionable wire and ground.)
XVII. NIGHT HEAT THERMOSTATS
The G-TRAC-2 control can be activated to control room heat at night. This requires the G-TRAC-2 be configured
for night operation and have a configured and equipped room thermostat. If there is a modulating or single stage
room thermostat connected to terminals “X, V, Y, and Z”, the night heat function will be activated when terminal
“K” is powered.
XVIII.ROOM RESET THERMOSTAT OPTIONS
The actual discharge temperature of the unit can be electronically adjusted or reset when the actual room
temperature deviates from the required room temperature. (Refer to these sections for a fuller understanding of the
room thermostat in your systems application):
Day/Night Operation (option) also refers to night information above.
Temperature Control information above and below.
Modulating Room Reset (option) using TE 6100 thermostat below.
Make/Break Thermostats (option) using a standard room thermostat below.
Additional technical information is also located under "Staged Resets and Overrides".
NOTE: When any override is calling, it will affect the "Calculated Set Point" and its relation with the
"Temperature Readout". It is recommended that the service technician be very familiar with these two
sections of the manual.
Modulating Room Reset (continuous blower operation only)
Dipswitch A-3 must be “on”. This option also requires a TE 6100 wired:
