Description
This is the first screen that appears
after pressing >, and shows the
actual
temperatures
measured
by the supply and return sensors.
NOTE: If the boiler is configured to
use a 0 – 10 volt input, the return
sensor is disabled and the second
line of the display will be blank.
The screen displays the current
central heating temperature set
point on the top line. NOTE: This
temperature set point may vary
from what was set in the boiler
settings if an outdoor sensor is used.
The actual temperature measured
by the supply sensor is displayed on
the bottom line.
This screen displays the central heat
demand set for the cascade system.
Shows if 0-10 volt is enabled.
This screen appears only when
the boiler is set as a Master Boiler.
This screen displays the cascade set
o
point (maximum 190
F) on the top
line. The system sensor reading is
on the second line. The control will
cascade the boilers up to this set
point depending on demand.
Displays
the
current
temperature set point on the
top line. The actual temperature
measured by the tank or return
sensor (Westinghouse 7250P-325)
is displayed on the bottom line. If
a mechanical aquastat is used in
place of the recommended sensor,
the second line will display 'OFF'
in place of the temperature if the
aquastat measures close to its set
temperature, or 'ON' if the aquastat
temperature is too low.
The current outdoor temperature
is displayed on the top line. If there
is no outdoor sensor connected
to the boiler, this line will display
"OFF" in place of the temperature.
If the outdoor sensor is shorted,
this line will display "ON" in place
of the temperature. The second
