Matrix Installation and Operation Instructions
9.2 Operation and Set-up
The Matrix employs a pneumatic modulation system. This modulation system increases or decreases the velocity of the combustion
blower, to meet the demand for heating. The gas valve senses this change in blower pressure and introduces the required amount of
gas to ensure correct combustion. The Sentry reads the boiler water temperature, compares it to the set point, and adjusts the burner
firing rate accordingly by varying the speed of the combustion blower.
The (Blue) Fan Controller communicates the appropriate demand and temperature set point to the (Red) Boiler Controller via a
series of digital and analog inputs. Table 9.3 shows the Boiler Controller's response to the demand. For more information on
'RESET MODE' see section '9.3 Outdoor Sensor Operation'.

9.2.1 Setting Matrix Boiler Control (Sentry)
Programming is accomplished by a series of three push buttons located on the bottom side of the control. (Function,
enter the programming mode, press the function key once. To scroll through the various menu options depress
displayed. To alter the value press Function once, and the current value will be displayed, then use
the desired value is obtained. To enter the selected value press Function, which will return to the menu. When all desired values are
selected, scroll to the RUN menu, and press Function, which exits the Programming Mode and initiates normal operation. A safety
feature has been added to ensure that if the control is left in the Program Mode, the unit will turn off if left in program mode longer
than 30 seconds without receiving an input. Press Function once to continue programming or to start boiler operation.
