Wiring the Boilers

• When wiring Condensing and Non-Condensing boilers make sure that Condensing boilers utilize the first stages
and Non-Condensing boilers will utilize the following stages. That is, if the installation had two Condensing
Modulating boilers and two Non-Condensing Staging On/Off boilers, Stage A and B will be used by the
Condensing boilers while C and D will be used by the Non-Condensing boilers.

Wiring Boiler activation or on/off staging Boilers

(A Terminals 5, 6), (B Terminals 7, 8), ...
• Each boiler output has a Normally Open (N.O.) dry-contact relay. They do not source any power.
• Wire the N.O. relay contacts in series with the unit's limit circuit.
• When connecting to On/Off boilers, each stage relay output will be connected to a single boiler.
• Class 1 voltages must enter the enclosure through a different opening from any Class 2 voltage wiring.
• Note that some modulating boilers may not require the use of these outputs.

Wiring Multi-stage Boilers

(For Staging Boiler Types Only) See Page 20
• Each multi-stage boiler must use only one of the N.O. relays and the
voltage output for that stage. The TempTracker mod+ Hybrid will
sequence the boiler stages using the 0-10V output signal.
• Note that on the display of the TempTracker mod+ Hybrid each
staging boiler will consist of a single letter.
• Each stage output has one Normally Open (N.O.) relay contact that
does not source any power.
• Class 1 voltages must enter the enclosure through a different opening
from any Class 2 voltage wiring.

Wiring to Modulating Boilers

The TempTracker mod+ Hybrid can modulate any combination of current or voltage boiler signals. The Modulating
Output Type must be set to match the boiler modulating signal before connecting any output wires to avoid
damaging components. See "Modulating Output Type" on page 24. Some modulating boilers may require the use of
the stage output relay in addition to the modulating output.
The Modulating Output Type must be set to match the boiler modulating signal
prior to wiring the boiler signal to avoid control or equipment damage.
