If there is no communication, check the following:
• Check that the polarity on the Modbus
®
+ and - terminals is correct
• Check that the Modbus
®
GDN terminal is securely connected.
• Check that the Baud Rate on both devices is the same.
If the communication is intermittent, check the following:
• Check that the communication cable is twisted pair type.
• Reliable communication depends on the cable length & Baud Rate used.
Long cable length may require a lower baud rate.

Sanitization
The Sanitization function produces high water temperatures and is intended ONLY for use as part of a user-
directed, controlled and supervised thermal eradication protocol that has been safely and properly designed
to help limit water-borne bacteria within the tempered water distribution system. The instructions contained
in this Manual for the Sanitization function are not intended to be a thermal eradication protocol.
Selecting, directing, and controlling a safe and properly designed thermal eradication protocol is the sole
responsibility of the people who own, manage or control the water distribution system. It is their responsibil-
ity to protect water distribution end-users, facility employees or contractors, and bystanders from scalding,
burning, thermal shock, or other hazards from possible exposure to water or any parts of the water distribu-
tion system during Sanitization and cool
1. On the Programming Menu Touch the
Sanitize
icon, which will direct you to the responsibility and liability
acceptance page:
2. You must touch the
ACCEPT
icon to proceed with the Sanitization function. Touching the
DECLINE
icon means you will be unable to utilize the Sanitization function and you will be returned to the
“Programming” Menu page. When you touch the
ACCEPT
icon, you will be directed to the Sanitization
menu screen.
The Sanitization function produces high tempera-
ture water at all point-of-use fixtures (faucets,
sinks, tubs, showers, etc.). Only qualified and
authorized personnel who fully understand the
function's operation, output and risks, should use
the Sanitization function, and only as part of and
in compliance with, a thermal eradication protocol
safely and properly designed by the owner or man-
ager of the water distribution system. The owner
or manager of the water distribution system has
sole responsibility to protect end-users, facility
employees or contractors, personnel performing
the Sanitization, and bystanders from scalding,
burning, thermal shock, or other hazards from
possible exposure to water or any parts of the
water distribution system during Sanitization and
cool down period, until system water returns to a
safe and proper outlet water temperature set point.
Always read and follow the User Guide & Instruction
Manual.
