• The amount of Setback selected is subtracted from the Set Point when a Setback Input Signal is received or the Night Time
schedule setting started.
• If Setback Input is selected as a Setback/Shutdown Mode (See page
15), the Setback will not be activated unless a dry contact
signal source is wired into the Shutdown/Setback terminals (31 and 32) and the TempTracker mod+ receives a SHORT signal.
• If Shutdown Input or TStat Input is selected as a Setback/Shutdown Mode
(See page 15), the Setback will be activated only when
Night Schedule time has started.

When using soft-off and last stage Hold, the last boiler stage will not turn off until both
parameters have elapsed. In this case, soft-off will start after the last stage Hold.

• The Last Stage Hold prevents short cycling of the Lead Stage during low load periods.
• In low load conditions, the system might require only 5% of the output of one Stage. When
the TempTracker mod+ brings on the Lead Stage, the Set Point is quickly exceeded, and the
TempTracker mod+ turns the Lead Stage off.
• To prolong the run time during this type of condition, use the Last Stage Hold setting.
• The TempTracker mod+ will let the system temperature exceed the Set Point by the number
of degrees selected, before the Lead Stage is turned off.
• For example, with a Set Point of 160°F and a Last Stage Hold setting of 10°F, the Lead
Stage boiler will remain on, at low modulation, until the Set Point reaches 170°F.
• From an efficiency stand point, it is better to overshoot slightly than to short cycle a boiler.

the temperature limits
set on the boilers must be
higher than the temptracker
mod+ set point. read the
section at left for details that
will prevent erratic system
operation.
Avoiding Conflicting Boiler Limits
• The temperature limits set on the boilers MUST be set considerably higher than the
TempTracker mod+’s Set Point for the reasons detailed below.
• The TempTracker mod+ sensor is located in a common header some distance from the
boilers.
• As the temperature rises in the header and before reaching the sensor location, energy is
dissipated. Therefore, the temperature in the header could be lower than that registered by
boiler sensors.
• In addition to the normal drop experienced between the boiler’s temperature and that
read by the TempTracker mod+ sensor, the Last Stage Hold setting must be accounted for. The boiler limit must be set above the
Set Point PLUS the Last Stage Hold PLUS the normal drop experienced in the piping.
• Using the previous example of a 10°F Last Stage Hold with a 160°F Set Point, the boilers’ limits must be set enough over 170°F
to prevent the boilers’ internal limits being reached. In this situation, the boiler high limit should be set at approximately 180°F to
prevent the difference in boiler temperature vs. header temperature causing erratic operation.

• The TempTracker mod+ has two levels of heat. The Day level is used when a building is
occupied and people are active.
• The Night (Setback) level is used when a building is not occupied, or when people are
sleeping. This setting reduces the calculated temperature by the Setback setting. If the Day
calculated water temperature was 150˚F and the Setback was 20˚F, the Night Schedule will
run at (150˚F - 20˚F) = 130˚F.

• If the Boost feature is being used, it uses the Day Schedule as a Boost ending point. That is, if the Day Schedule is set to start at
6:00AM, the Boost will start 30 minutes prior to the Day setting at 5:30AM. The TempTracker mod+ will then raise the calculated
water temperature by the Setback amount. Using the previous example, at 5:30AM the TempTracker mod+ will raise the
calculated water to 170˚F (150˚F + 20˚F) until 6:00AM.
