OPERATION
TIME SWITCH OPERATING INSTRUCTIONS
1. TO SET "ON" AND "OFF" TIMES:
Hold TRIPPERS against edge of
CLOCK-DIAL, pointing to time (AM or
PM) when ON and OFF operations
are desired. Tighten tripper screws
firmly.
2. TO SET TIME-OF-DAY:
Pull
CLOCK-DIAL outward. Turn in either direction and align
the exact time-of-day on the CLOCK-DIAL (the time now,
when switch is being put into operation) to the pointer.
• TO OPERATE SWITCH MANUALLY:
Move MANUAL
LEVER below CLOCK-DIAL left or right as indicated by
arrows. This will not affect the next operation.
• FOR MORE THAN ONE DAILY ON-OFF OPERATION:
Place additional tripper pairs on CLOCK-DIAL (order
156T1978A).
• IN CASE OF POWER FAILURE:
Reset CLOCK-DIAL
to proper time of day. See step 2 above.

TO SET THERMOSTAT, turn dial, pointing to
desired temperature between 32˚F and 45˚F,
marked on the plate. Remember, many
variables, such as the location of the Freeze
Protection Control, the location of equipment
and the pool or spa, the location and
insulation of the plumbing, etc., must be
considered before selecting the “turn ON”
temperature of the filter Pump. Your local pool
service professional is the best source of
information. The Thermostat is factory set to
turn OFF the Filter Pump when the ambient
temperature rises 5˚F above its set point.
TO SET TIME SWITCH, if Intermatic, follow
instructions on the right. If other than
Intermatic, follow instructions inside enclosure
cover. The length of the daily filtration/heating
cycle depends on many variables such as
size, shape, and geographic location of the
pool, water chemistry, type of pool equipment
usage and season of year. If not sure, contact
your local pool service professional for advice.
