Programming Instructions to program the Fireman’s Switch Timer.
Programming the Fireman’s Switch
NOTE: Please reference the heater owner’s manual for for your heat exchanger’s recommended
cool-down time settings for the Fireman’s Switch.
Program your desired ON and OFF times on your Pump Timer for
your lter pump.
Program the same ON time as your Pump Timer for the Fireman’s
Switch Timer.
EXAMPLE: Assuming the heater owner’s manual recommends a ve-
minute cool-down time for the heat exchanger:
Program an OFF time on the Fireman’s Switch Timer that is ve
minutes less than the OFF time programmed on the Pump Timer.
This will ensure that the heater is OFF for at least ve minutes
before the pump shuts down, allowing proper cool down.
