a second time. The heater will now display |Ch| and an alternating value of 15. This is the
Heater Differential Set Point. This function allows the installer to adjust the activation of the burner based
on the differential temperature setting of the heater. The burner will not start until the outlet water
temperature reaches a temperature equal to the setting for the heater, minus the differential.
EXAMPLE: The heater is set to heat at 180°F and the differential is set at 15°F. The burner will not start
until the outlet temperature of the system reaches 164°F (180° – 15° = 165°).
