2F-2. Auxiliary Time Clock Wiring (LD)

If you install a time clock to control the filter pump operation, it is recommended that the time clock have its own low voltage (Fireman’s) switch to turn off the heater before turning off the pump. The switch should shut off the heater about 15 minutes before the filter pump shuts off. This will allow for a more

efficient operation by removing any residual heat contained in the heat exchanger back to the pool.

Caution

Do not provide power to the heater from the high voltage side of the time clock. Doing so may cause damage to the heater or surrounding plumbing.
