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.

CONTROL OPERATION

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 specic 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.
