Intermatic Timer, 120-240V Mechanical Timer w/ Heater Protection in Metal Enclosure
This heavy duty Mechanical Time Switch is designed for industrial, commercial and residential applications and has the highest motor load ratings in the industry. They provide up to 12 ON-OFF operations each day with a minimum ON-OFF time of 1 hour. The T100R201 Series Time Switches are designed to turn OFF a gas fired swimming pool heater approximately 20 minutes before the filter pump shuts down. This eliminates the problem of pounding and knocking due to overheated water, reduces scale and lime deposits and extends the service life of the heater.
