Simple Serviceability

Raypak’s easy-to-understand user interface, including
on-board diagnostics and LED operating status lights,
tells the technician all he needs to know. All
service/repair components are readily accessible from
the front or side for maximum installation flexibility.
To enhance serviceability, the control box is completely
removable allowing total access.

TempTracker Mod

Raypak’s XTherm comes standard with TempTracker Mod. This control can be used for
space heating and hot water supply with 8 application-specific modes to meet various
applications, including outdoor reset for heating systems. The control monitors and dis-
plays inlet and outlet temperatures on all applications as well as monitor outdoor tem-
perature when an outdoor reset mode is selected. Only Raypak’s TempTracker Mod
allows for a user definable outdoor reset ratio. Adjustable limits prevent over-cycling,
saving energy and extending the life of the heater. Your XTherm is never down with a
sensor failure thanks to Raypak’s exclusive TempTracker software. It can operate with as
little as one functioning sensor, keeping you up and running until service arrives.

On-Board Diagnostic Center

Raypak’s XTherm comes equipped with a microprocessor-controlled diagnostic control center that displays its information on a
2x20 character LCD display in plain English. This control monitors system safeties, ignition faults and system status, while storing
up to 16 reported faults. Raypaks diagnostic center monitors the fault outputs of the Fenwal ignition control. Converting the
Fenwal’s flashing lights into real English fault codes that anyone can understand. The control is also equipped with a SPDT dry
contact relay output that is switched anytime a safety fault occurs. This can be used for a heater alarm or a BMS safety interface.
