  • Page 5: Purpose

    G-TRAC MANUAL G-TRAC CONTROL FOR MODULATING DG UNITS If you note any errors, omissions, or items that require further clarification, please contact Wade Pascoe at (403) 287-4775 or Fax (403) 287-4799 or (403) 243-5059. To ensure warranty is honoured, only a qualified HVAC service person or gas fitter that has received training on the G-TRAC, should be employed for service and troubleshooting.

  • Page 6: Temperature Control

    G-TRAC MANUAL  The flame relay (external to the G-TRAC) energizes the ignition transformer and pilot solenoid valve.  When the pilot is established, the flame relay will power the main gas valve and shut off the spark.  The G-TRAC and its associated controls maintain the discharge air temperature. If the rise in discharge air temperature at low fire is greater than that required to satisfy the set-point, it is necessary to cycle the burner on and off.

  • Page 10: Multiple Room Sensors

    G-TRAC MANUAL Multiple Room Sensors Four sensors can be wired to give an average reading of room temperatures to the Trac cntrol. They must be wired in a series/parallel arrangement. The drawing shows a circuit making use of the built in sensor in the T#6100 Johnson Sensor/set point assembly and using TE6000 sensors for the other three.

  • Page 11: Method 1

    G-TRAC MANUAL  Jumper the combustion blower.  Jumper the flame relay terminals.  Place a Q209 Honeywell 140 ohm pot on the V9055 valve to modulate it to a fixed position and allow it to run until discharge air temperature is stable in the modulated area of the valve stroke and between 55 to 90ºF.

  • Page 12: Method 3

    G-TRAC MANUAL  Place a 1005-ohm resistor across G-TRAC terminals "X and Z" to simulate 70°F (21°C).  Connect the TE 6100-960 set-point to the G-TRAC terminals as follows: 1. BLUE to G-TRAC terminal Z 2. ORANGE to G-TRAC terminal Y 3.
  • Page 13 G-TRAC MANUAL Approximate relationship between 0-10 VDC and 4-20 ma signal. Note: zero reset less than 2 VDC or less than 1 ma There is a possibility of a grounded BMS signal that is not fully recognized by the G-TRAC. This occurs when the BMS control signal’s negative wire and the G-TRAC’s 24 volt power supply both have a grounded negative or common terminal.

Do not readjust without insuring that no reset signals are affecting discharge temperature (Page 7). P2 ROOM RESET RATIO – This sets the amount of authority the room reset will have on the set-points desired discharge.

  • Page 15: Pre-Purge Timer Light

    G-TRAC MANUAL Pre-Purge Timer Light The pre-purge timer light will activate when there is a call for heat and the burner is in the pre-purge mode. The combustion blower should be running but there should be no flame. When this light goes out, if the heat call is still present, the burner-enabled light will come on.

    G-TRAC MANUAL Over Delivering Air At the time of installation and air balancing, the unit is often set-up in warmer weather then the design temperature rise. If the air balancer did not allow for the changes that will occur in air volume in cold weather then the unit will appear to be short of temperature rise.
