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..

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 efcient 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.

Button: MENU/<System Startup>/..../Prove-DHW Sharing

• 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.
