Wet Rotor Circulator Pumps
PFWRC66B1S
OPTIONAL: PFDT - 7-Day Digital Timer
The digital, programmable timer allows for control of the circulator
(on / off) at designated times (up to four custom settings per 24 hour
period) for up to 7 days (similar to a programmable thermostat). The
timer is plugged into a standard wall outlet and the circulator pump is
then plugged into the timer allowing for time control of the pump. This
unit has an internal battery backup which will, in the event of loss of AC
power, power the unit and save / maintain program settings (battery will
last for 48 hours before needing to be recharged).
NOTE: The Digital timer (PFDT) and Aquastat (PFSOA) can ALSO be used
together, in tandem to allow for BOTH temperature AND time control.
OPTIONAL: PFSOA - Snap on Aquastat
The Aquastat simply “clips” onto any material 1/2” ID or 3/4” ID piping. It
then plugs into a standard wall outlet. You would then plug in the power
cord for the circulator into the aquastat plug and it will turn the circulator
on and off automatically at fixed set points (ON 98°F and OFF at 114°F)
allowing for temperature control of pump. 8 Ft. Cord.
NOTE: The Digital Timer (PFDT) and Aquastat (PFSOA) can ALSO be
used together, in tandem to allow for BOTH temperature AND time
control.
