4 SMART SYSTEM control module (continued)
Temperature Units
The control can be configured to display temperature in
either °F or °C. This parameter can be changed by the user
or the installer by accessing the Temperature Units parameter.
The default is °F. To change the temperature units, access
the clock menu as described in the User section (this page).
Rotate the NAVIGATION dial until the arrow (>) is pointing
to “TEMPERATURE UNIT °F”. Press the NAVIGATION
dial once. The temperature unit will begin to flash. Rotate
the NAVIGATION dial until the desired temperature unit
is shown. Save the new setting as described in the Saving
Parameters section (page 10).
Night Setback Override
Any Night Setback On trigger currently active or scheduled
within the next seven (7) days can be skipped. To skip a
trigger, rotate the NAVIGATION dial until the arrow (>) is
next to the trigger you wish to skip. Press the NAVIGATION
dial once. “SK” will appear next to that trigger to indicate
that it will be skipped. You can restore an upcoming trigger
by selecting that trigger, and pressing the NAVIGATION dial
again. The “SK” next to that trigger will disappear.
To save any changes and return to the Home Screen, press
the RIGHT SELECT [HOME] key. To return to the Status
Screen without saving the changes, press the LEFT SELECT
[EXIT] key.
In compliance with Energy Conservation Standards, this boiler
is equipped with outdoor air reset, a feature that saves energy
by reducing the boiler water temperature as the heating load
decreases. Three (3) individual outdoor resets for low outdoor
temperatures are available. The reset curve parameters can be
changed by the installer by accessing the Outdoor Reset menu.
There are three (3) individual user set points for better zone
control. These are listed as SH1 Set Point through SH3 Set
Point. These set points provide a maximum boiler water
temperature limit to the outdoor reset curve of each zone. The
boiler operating set point is calculated from the individual reset
curve of each zone. If multiple space heating set points are
calling for heat the highest set point has priority. The range is
SH Minimum Set point to SH Maximum Set point (32°F (0°C) -
190°F (88°C)). The default is 125°F (52°C).
By installing a tank sensor, the SMART SYSTEM control can
perform the tank thermostat function. The SMART SYSTEM
control automatically detects the presence of this sensor, and
generates a DHW call for heat when the tank temperature
drops 6°F (-14°C) below the tank set point differential (Tank
Set point Differential parameter), and finishes the call for heat
when the tank temperature reaches tank set point + offset.
This parameter can be changed by the installer by accessing the
DHW Tank Set point parameter. The temperature range of this
parameter is 68°F (20°C) to 190°F (88°C). The default value is
125°F (52°C).
Press the NAVIGATION dial once. A menu will appear
showing the SH1, SH2, SH3, and DHW Set Points. Rotate
the NAVIGATION dial until the arrow (>) is pointing to the
setting you wish to change. Press the NAVIGATION dial again.
The value of the selected setting will begin to flash. Rotate the
NAVIGATION dial to adjust the value. Save the new setting as
described in the Saving Parameters section (page 10).

CAUTION
Mixing valves are required for the
protection of any low temperature loops.
