sensor Inputs
display shows sensor open or sHort
When OPEN, Check the sensor is connected and the wires are continuous to the TempTracker
mod+. Finally follow the procedure for Incorrect Temperature or Pressure Display. When
SHORT Remove the wires from the sensor terminals. The display should change to read OPEN.
If it does not, the TempTracker mod+ may be damaged.
display shows an Incorrect temperature
Remove the wires from the sensor terminals. The display should change to read OPEN. If it
does not, the TempTracker mod+ may be damaged. Take an ohm reading across the detached
sensor wires. The ohm reading should correspond to the Temperature sensor Table. If it does
not, the sensor may be damaged.

no Heat
• Season
- Make sure that the Season is set to Winter. Check Message Display Line on page 24.
• Prove
- Even though, the system relay may be energized, the TempTracker mod+ will not
energize and stage relays unless the Prove is shorted. Check Message Display Line on page 24.
• Shutdown
- The TempTracker mod+ will activate stage outputs when the Shutdown terminals are
short. Check Message Display Line on page 24.
• Tstat
- The TempTracker mod+ will activate stage outputs when the Tstat terminals are open.
Check Message Display Line on page 24.
• Sensor Fault
- When the Sensor Fault is set to All Off in the startup menu (see page 16), the
System sensor fault (in all Sensor Type modes) or the Outdoor sensor fault (in Reset mode) will
de-energize all stage relays. Check the display for sensor values.
• System or Outdoor Sensor
- If the System or Outdoor sensor reading was higher that the actual
temperature, the TempTracker mod+ might not bring any stage on. Check "Display shows an
Incorrect Temperature" section.
too Much Heat
Check if the control has any of the following:
• Domestic Hot Water call
- The TempTracker mod+ will raise the temperature of the system to
the DHW Set Point on a DHW call, connected to terminals 29 and 30. Check to see if there is a
call for DHW and the length of time it lasts.
• Reset Ratio and Offset
- If excessive heat occurs only in certain weather conditions, adjust the
Reset Ratio and Offset (See Understanding Operating Concept on page 5). If excessive heat
occurs year round, reduce the Offset.
• Boiler Mode Settings
- The TempTracker mod+ will only modulate boilers their mode is set to
Auto or Standby. Check to if any boiler stage is set to Manual or On. See Mode on page 25.
• Control Settings
- The Last Stage Hold will allow only the Lead boiler to stay on for an
additional number of degrees. If the setting is too high, and only the Lead boiler is on, the system
can over heat. Reduce the Last Stage Hold setting. See page 21.
too little Heat
Check if the control has any of the following:
• Reset Ratio and Offset
- If reduced heat occurs only in certain weather conditions, adjust the Reset Ratio and Offset (See
Understanding Operating Concept on page 5). If reduced heat occurs year round, increase the Offset.
• Setback and Day/Night Schedule
- If reduced heat occurs only during specific hours, check the Day/Night Schedule and the
Setback values. Either reduce the Setback setting (See page 20).
• Boiler Mode Settings
- The TempTracker mod+ will only modulate boilers their mode is set to Auto or Standby. Check if any
boiler stage is set to Manual, Off, or Standby. See Mode on page 25.
