Boiler Control and
On-Board Diagnostic Center
Raypak’s XFyre comes equipped with a microprocessor control
center that displays its information on a 2x20 character LCD
display in plain English. All set-up and programming is done at
this interface. Control monitors boiler system status including
safeties, ignition faults and also stores up to 10 reported faults.
The diagnostic center even monitors and reports the flame
strength signal in microamps. Monitor blower speed, BMS
input and all water and air sensors. A normally-open and nor-
mally-closed dry contact alarm relay is provided.
Outdoor Proven
Raypak is no stranger to the outdoor environment. Our touchpad is 100% waterproof and has been proven and perfected on our
pool products. No guesswork here, just one tough boiler ready to take on jobs that others have to walk away from.

The XFyre comes standard with a built-in Cascading Boiler Control. No other controls to buy, just daisy chain the units together
with CAT 3 or CAT 5 computer network cables
(not supplied) that plug into the front mounted communication bus on each unit
(see low voltage wiring box opposite page) . Designate a Cascade Master Boiler and set all the other boilers as Followers. It’s that sim-
ple! The XFyre has built-in Lead-Lag control. This allows rotation of the starting boiler so all boilers in the system remain active
and the run times remain equal on each unit. Rotation can even be programmed based on time, ensuring equal run times per
unit.
