E1/E3 Series - Timer
Description
To increase the overall efficiency of a domestic hot water recirculating system and to reduce water wasted while
waiting for hot water, the E1/E3 Series Timer can be installed on all E1/E3 Series pumps. The timer is easily
installed by removing the motor end cap, plugging in the timer and setting the timer schedule without any
wiring. The timer can be used in 3-different selections: ON, OFF and TIMER. The ON selection operates the pump
continuously, the OFF selection turns the pump OFF and the TIMER selection (depicted by a clock on the timer)
turns the pump on when programmed.
