Enter the menu labeled Setpoint
in the upper right of the display
to set the desired operating water
temperature. On a boiler, this will
be based on the leaving water
temperature. On a water heater it
will be based either on a connected
external (storage tank) sensor, or,
if there is none connected, it will
operate based on the incoming
water temperature. The range is
factory-set at 50–160°F for water
heaters and 50–195°F for boilers.
Other special ranges are available
by contacting the factory.
If other
temperature settings are required,
contact Hamilton Engineering
Company, Inc.

a password in the display, varying
from end user, installer, advanced,
and factory levels. The display can
show either °F or °C set in the setup
