When an external tank is used on the boiler and the tank sensor is
not a factory authorized accessory, ensure that the relative indirect
tank sensor (NTC sensor) has the following characteristics: 10
kOhm at 77°F (25°C), B 3435 ±1%.
Ask you installer or servicer about the kit KBANT0101111 available
for purchase.
3.11 GENERAL SAFETY
9
Water temperatures over 125°F (52°C) can cause instant
severe burns or death from scalds.
When supplying general purpose hot water, the recommended
initial setting for the temperature control is 120°F (49°C).
Safety and energy conservation are factors to be considered when
setting the water temperature on the thermostat. The most energy-
efficient operation will result when the temperature setting is the
lowest that satisfies the needs of the application.
Children, disabled, and elderly are at highest risk of being scalded.
− Feel water before bathing or showering.
− Temperature limiting valves are available.
NOTICE (for heating only model): When this boiler is
supplying general purpose hot water for use by individuals, a
thermostatically controlled mixing valve for reducing point of
use water temperature is recommended to reduce the risk of
scald injury. Contact a licensed plumber or the local plumbing
authority for further information.
Maximum water temperatures occur just after the boiler's burner
has shut off. To determine the water temperature being delivered,
turn on a hot water faucet and place a thermometer in the hot water
stream and read the thermometer.

WARNING: This boiler cannot supply hot water for use
by individuals directly. A heat exchanger must be used in
conjunction with this boiler to meet DHW needs.
3.12 SCALDING TIME/TEMPERATURE
RELATIONSHIPS
The following chart details the relationship of water temperature
and time with regard to scald injury and may be used as a guide
in determining the safest water temperature for your applications.

The temperature of the water in the boiler can be regulated by
using the boiler front control. To comply with safety regulations, the
control is set to a lower temperature when shipped from the factory.
CAUTION: Hotter water increases the risk of scalding. There is a
hot water scald potential if the thermostat is set too high.
3.13 ACCESS TO THE INFO MENU
NOTICE: Make sure you are in the "Operation mode", backlight
ON (see section "3.6 PROGRAMMING THE BOILER").
Using the boiler control panel it is possible to access the INFO
menu by pressing the "MENU/RESET" button one to illuminate the
screen, then again for less than 5 seconds. The INFO menu allows
the user to view some of the boilers sensor readings and can be
very helpful when diagnosing issues with the unit (see INFO list in
the next column; indexed by a lowercase alphabetical letter.).
Note: Pressing the "MENU/RESET" button for more than 5
seconds will access the Parameter menu. This menu will timeout
with inactivity in about 30 seconds if accidental accessed.
Once the button is pressed, the first value of the INFO menu
appears: e. g. "a130.6°F".
It scrolls from right to left because of the length of the string (up
to 5 characters) in the following sequence: letter + value + unit of
measure.
To move from one letter to another press the "MODE/OK" button.
The next value will appear: e. g. "b135.1°F" (sliding from right to
left).
To exit INFO menu, press "RESET" button again, or wait 10
seconds for automatic exit.
