    The fan controller controls the forced air modulation, ventilation, as well as priority of domestic hot water and secondary heating systems. ATTENTION The Matrix Boiler Control (Sentry) is different from the Sentry controller used on any other NTI products and is NOT INTERCHANGEABLE. 9.1 Controller Displays 9.1.1 Matrix Boiler Control (Sentry) Display (Red Face Plate)
  • Page 34 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.

If HRV set to ‘ON’, HRV will operate at the low (continuous) ventilation rate. Call for Auxiliary Heat (24 VAC @ W2): When calling, furnace will provide heat at a stage 10 output rate. With a call for auxiliary heating the Matrix will function as a single stage, full fire appliance.

  • Page 39: Heat Recovery Ventilation

    Matrix Installation and Operation Instructions 11.0 HEAT RECOVERY VENTILATION 11.1 Ventilation Needs With the evolution toward more energy efficient, tighter homes, air quality problems have increased. With less natural ventilation pollutants such as pet dander, humidity, tobacco smoke and wood ash now become trapped inside the home. Mechanical ventilation is the process of exhausting the polluted air from the space and replacing it with fresh air from outside.
