TC-1 Automatic Timer Kit (Part No. 113210)
To increase the overall efficiency of a hot water recirculation
system, the TC-1 timer control kit can be installed for use on any
B&G NBF circulator. The TC-1 timer control is programmable to
turn the circulator ON and OFF automatically at preset times. This
permits the user to have the pump circulate hot water only during
those times when high usage can be expected throughout the
day. Power supply minimum interval switch is 15 minutes.
Run modes maximum switch current is 16 amps.
Description
To increase the overall efficiency of a domestic hot water recirculating system and to reduce water
wasted while waiting for hot water, the e
3
Timer can be installed on all e
3
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.

OFF. The AQ-1/2 or AQ-3/4 will switch the pump OFF at 120ºF
(48.9ºC) and ON at 100ºF (37.8ºC). The aquastats are available
in separate models that will sense the temperature for either
1/2” or 3/4” copper pipe.
AQS-1/2” clips onto 1/2” copper pipe or 3/8” steel pipe
