In response to new advancement in condensing boiler design and size, many applications utilize multiple condensing boilers in
addition to the non-condensing boilers. That triggered Raypak's patent design of the TempTracker mod+ Hybrid . It is intended to
manage the two groups of boilers to maximize system efciency at the lowest operating cost while maintaining the desired comfort.
When Hybrid is selected as the Boiler Type, the TempTracker mod+ Hybrid will operate each group based on the Target temperature
switching set point. See "Boiler Type" on page 20..
Each of the condensing and non-condensing groups of boilers can be either modulating or staging. Modulating boilers can be of
4-20mA modulating signal or 0-10V modulating signal.
Staging boilers must be of the 0-10V signal.
Depending on the actual System Temperature, the
TempTracker mod+ Hybrid will determine which
group of boilers will be the lead and which group will
be the lag group. The Condensing group of boilers
will be the Lead group when the System temperature
is below the System Target Switching Set Point.
However, when the System temperature rises above the
Switching Set Point, the Non-Condensing boiler group
will be the lead group and the Condensing Group will
be the lag group.
Basically, the TempTracker mod+ Hybrid will allow
the condensing group of boilers to operate as along as
the System sensor is below the Switching Set Point.
See"Switch Set Point" on page 21. During that period,
if additional output boilers are needed, the TempTracker mod+ Hybrid will energize the Non-Condensing boilers to meet the load.
See"Heavy Load Sequence 2nd Group" on page 22. When less output is required the TempTracker mod+ Hybrid will de-energize the
Non-Condensing boilers prior to de-energizing the Condensing boilers.
To eliminate any short-cycling due to rapid changes in the Target Temperature used in the switching, an adjustable Switching Delay
has been incorporated. See"Switch Delay" on page 22.
For Hybrid settings, See "Boiler Type" on page 20. See "HYBRID Startup Settings" on page 21.
To set the Condensing and Non-Condensing boiler types See "HYBRID Modulating Boiler Settings" on page 23. Also, See "HYBRID
Staging Boiler Settings" on page 23.
