6.7 FROST PROTECTION
The Dynaforce® is equipped with a heat exchanger frost
protection algorithm where if the boiler inlet or outlet
temperature sensors drop below 41
o
F (5
o
C) the boiler pump is
enabled. If the temperature continues to drop to 38
o
F (3.3
o
C) the
burner will be fired to bring the inlet and outlet temperatures to
50
o
F (10
o
C) to prevent freezing of the heat exchanger.
