Product Overview

Wiring diagram
Wiring diagram with auxiliary
micro-switch for code 656314
and 656414 actuators:
The auxiliary micro-switch can be
used to turn off the pump when
there is no call for heat and the
valves are closed. If the pump
power consumption exceeds the
contact rating of 5 A, a relay must
be used.
The auxiliary micro-switch shuts off at an average actuator opening
value of 80%.
Using the TwisTop™ 656314 actuator
1. Normal operation in automatic
mode.
In automatic mode, the thermo-electric
actuator opens the valve when it
is supplied power. The opening is
displayed by the central disc raising
on the top of the knob and the green
circular indicator.
2. Simply twist to manually open
actuator (and activate micro-
switch on 656314).
Turn the knob on the top of the
actuator counterclockwise until
the limit stop trips and the arrow
symbols and hand symbol align.
To close the valve manually and
restore automatic operation, turn the
knob clockwise to “AUTO”. For the
656314 with auxiliary micro-switch,
the micro-switch contact is closed
when in the manual opening position.
3. When power is applied it
returns to AUTO position.
When the actuator in the manual
position is powered, an internal
mechanism enables automatic
release from the position and a
return to normal operation. A few
seconds after powering up, the
knob will automatically return to the
“AUTO” position and the opening
indicator will stay in the open
position.

Using the 6564 series actuator
Opening/closing indicator
The 656414 thermo-electric actuator, when electrically powered,
opens the valve. The opening is displayed by the central disc raising
on the top of the knob and the green circular indicator. The opening/
closing indicator is especially useful during testing to check for proper
operation without having to activate the system.
