Application:The Taco Clock Timer/Temperature Aquastat combination isdesigned to cycle the circulator during peak demand peri-ods. The Analog Timer (No. 265-1) is adjustable to 15 minuteintervals within a 24 hour time frame. The Digital Timer(No. 265-3) can be programmed for 7 day operation. TheTemperature Aquastat (No. 563-2) automatically switchesthe circulator ON at 95ºF and OFF at 115ºF. The two canbe used in combination, or they can be used separately.When the Clock Timer/Temperature Aquastat are usedtogether, the Timer switches ON sending power to the unit.The Temperature Aquastat measures the temperature, andcycles the circulator as long as the Timer is switched to theON mode.If used separately, the Clock Timer operates the circulatorduring the chosen number of ON/OFF intervals. When usingonly the Temperature Aquastat, the circulator cycles inter-mittently to maintain a temperature between 95ºF and 115ºF.The Clock Timer and Temperature Aquastat are easy toretrofit to any “00” Series Circulator.
