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.
Note:
1-
For Combi units the Heating Circ. (C1) is powered for both heating and domestic hot water.
2-
For Combi units the Aux Circ. (Ap) powers the 3-way diverter valve. (Located in the boiler)
3-
For Combi units the boiler will run in domestic mode immediately following a call for heat or domestic, until a boiler temperature of
160
o
F in reached.
4-
For Combi units the burner turns on when the water temperature is less then 190
°
F on the initial call, afterwards it turns back on when
water temperature is less then LO set point.
