• If either of the Condensing or Non-Condensing Boiler groups was set to Modulating as the
Boiler Type, 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.
• The modulating output for each boiler can be congured to 4-20mA operation (Current) or
any of the 0-10V voltage options. Check the boiler to determine its signal requirements.
• There are two 0-10V modulating options; a 0-10V and a 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.

Normal,Parallel Default:Normal
Button: MENU/<System Startup>/..../Output A Type/Condensing 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 boilers
with low turndown ratios.
• Most 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

not cover failed components
caused by improper wiring. See

A single Hybrid Multi-Stage
boiler will use ONLY one output
relay for activation and the
0-10V output signal for staging.

• The TempTracker mod+ Hybrid can sequence multi-stage boiler starting with a single On/
Off and up to a 4-stages. Just select the number of stages per boiler from this menu option.
• For each Hybrid multi-stage boiler a single output relay will be used in addition to to the
0-10V output signal.
• The number selected applies to all sequencing boilers within that group whether it is
Condensing or Non-Condensing.
