On/Off,2-Stage,3-Stage,4-StageOutputs Default:On/Off
Button: MENU/<System Startup>/..../Output Type
• The TempTracker mod+ Hybrid can sequence any type of multi-stage boiler starting with a
single On/Off and up to a four 4-stages. Just select the number of stages per boiler from this
menu option.
• Each boiler must be connected to one of the relay outputs. In addition to the stage relay the
corresponding 0-10V output signal must be used to provide staging..
Adjustablefrom1to15 Default:1
Button: MENU/<System Startup>/Boiler Type/.../Boiler Number
• Select the number of staging boilers. This number multiplied by the number of stages for
each boiler will determine the total number of stages required.

Make sure that boiler wiring
matches the Boiler Type
selected. Warranty will not
cover failed components caused
by improper wiring. See "Wiring
the Boilers" on page 14.

Button: MENU/<System Startup>/..../Output Type/Staging Mode
• During low load conditions, some boilers run more efcient when the lower stages are
energized alone than with the higher stages. For these types of boilers select Lo/Lo/Hi/Hi.
Then, the TempTracker mod+ Hybrid will sequence the lower stages of all boilers set to
Auto before sequencing the higher stages.
• For the rest of the boiler types, the Lo/Hi/Lo/Hi should allow the staging of the lower stage
of the lead boiler followed by the higher stage of the same boiler. Then when more stages
are needed, it will re the lower stage of the lag boiler followed by the higher stage of the
lag boiler.

• This setting determines the functionality of input terminals 29 and 30.
• When Prove is selected, the TempTracker mod+ Hybrid will not start any boiler unless
the Prove terminals are shorted/closed. However, it will allow the System relay to operate
normally.

• There are three DHW Priority options. In all the options, a DHW call will raise the
calculated water temperature to the DHW Set Point (See next setting).
• The Domestic Hot Water Priority option de-energizes the System relay during domestic hot
water calls for a period of one hour. If after the priority period the DHW call did not expire,
the System relay will energize providing heat to the building and the temperature target will
remain at the DHW Set Point. After the DHW call ends, the set point will drop to satisfy the
reset ratio or set point.
• Domestic Hot Water No Priority option allows the System relay to remain energized during
a domestic hot water call (aquastat call on terminals 29 and 30). However, in Summer,
Shutdown, No Tstat call for heat, or when the outdoor temperature is above Outdoor Cutoff,
a DHW call will energize the System relay. After the DHW call terminates, the System relay
will continue to run for the System Run-On period before turning off.
• Domestic Hot Water No Priority (Summer) behaves the same as the DHW No Priority.
The only difference is that in Summer, Shutdown, No Tstat call for heat, or when outdoor
temperature is above Outdoor Cutoff, a DHW call WILL NOT energize the System relay
except for the Run-On delay after the DHW call ends.
