The control will enter “Storage Mode” if the burner is on at the end of a demand. Once in “Storage Mode” the burner goes to low fire, the 3-way diverting valve is energized (position “A”), and the circulator is powered until a boiler temperature of 160°F is reached, at which point the control reverts to “Standby Mode”.

Once the room thermostat is satisfied, it breaks power to the TT terminal of the pump controller, which opens the X –X contacts, which opens the T-C circuit. The Pumps and burner turn off. In an injection system, it is important to understand the effect of flow and temperature set points. It is recommended that the Sentry controller’s set point is at least 20°F higher than the desired Mix temperature of the Hottest Loop. - Page 26 Setting Sentry 2100T Operation The Trinity boiler employs a pneumatic modulation system. This modulation system increases or decreases the velocity of the 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 term “Set Point” is used to indicate the desired temperature that the Trinity will try and maintain, by increasing or decreasing the input.
