• 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 stages

• The TempTracker mod+ Hybrid will offer the capability of controlling a variety of
modulating signals. Each boiler can be congured to have a different modulating signal.
Check the boiler to determine its signal requirements.
• The 4-20mA modulating option, starts the boiler at 50%. then modulate up or down based
on the need. The minimum modulation for any of these boilers will be the Ignition %. See
"Ignition %" on page 41.
• There are two 0-10V modulating options; a 0-10V and 1-10V Custom. The 0-10V starts the
boiler at 50%. then modulate up or down based on the need. The minimum modulation for
any of these boilers will be the Ignition %. See "Ignition %" on page 41.
• The 1-10V Custom option gives the user the capability of adjusting the voltage level
at which the boiler starts using the Ignition %. It shall be used on any Raypak 0-10V
modulating boiler. The Ignition % will be the level at which the control will output 1VDC.
• When using the Extension, connect it to the TempTracker mod+ Hybrid prior to conguring
the Output Type. Otherwise, the TempTracker mod+ Hybrid might not recognize the
Extension stages.

Button: MENU/<System Startup>/..../Output A Type/Modulating Mode
• Some modulating boilers perform better at higher modulation. For these units, it is
advantageous to run one unit at high modulation than several units at lower modulation. If
the units used are of this type, select Normal. This is the recommended setting for typical
steel and cast iron boilers or boilers with low turndown ratios.
• There are many condensing boilers that run more efciently at lower modulation. If it
is more energy efcient to run several units at lower modulation than one at high, select
Parallel. This is typically used on condensing boilers or boilers with high turndown ratios.
• For best Parallel performance, set the Modulation Start % to be equivalent to the lowest
ring rate of the boiler multiplied by 2. That is, if the lowest ring of the boiler was 20%,
set your Modulation Start% to 40%. See "Modulation Start %" on page 41.
• Set the Lag Delay to 0 for better parallel performance. See "Lag Delay" on page 35.

Make sure that boiler
modulation wiring matches the
signal selected. Warranty will
not cover failed components
caused by improper wiring. See
