The PAW constant temperature controller PKR6 is easily
attached to the mixing valve with a patented snap-in
mechanism.
It is fixed with a stop bolt, which is included in the scope the
delivery.
In addition, this stop bolt serves as an anti-rotation device.
Because of its compact form and the small dimensions, the
constant temperature controller PKR6 fits into the cut-outs of the
insulations of all PAW heating fitting groups.
The scope of delivery of the PAW constant temperature
controller PKR6 includes a Pt1000 sensor (with G¼" ext. thread)
to be mounted in the flow ball valve or in a sensor connection
piece (DN 20).
The rotation angle (adjustment range) is limited to 90° by limit
switches. If the end position has been reached, the actuator is
switched off, resulting in a currentless actuator.
The constant temperature controller can be switched to manual
operation by pushing the button (●push○). By doing so, the gear
is disengaged and the mixing valve can be set as required with
the manual rotary handle (position indicator).
Behind / below the manual rotary handle is a perforated scale to
indicate the mixing valve position. In the condition of delivery,
the actuator is in the centre position.
