The addressing through microswitch with several ways is not relevant when
K282 actuator is used as single device (stand-alone conguration): it is not
necessary to make any conguration in this application.
All microswitch sliders are positioned on “OFF” (side with 1-8 numbers)
on delivery. K282 actuator uses selectors from 1 to 6 to assign an address
between 0 and 31: check the address to assign on the design documentation
of the system.

Installation
1) Unscrew the handwheel protecting body before assembling and adjust
the shutter manually on R298 or R298N valve.
2) Fix K282X022 actuator through its apposite brass xing ring: the ring
must be screwed to the valve body up to end stroke in order to ensure max.
stroke to the shutter.
3) Insert the immersion probe in a R227 pit, downstream of the secondary
circulator, and block by means of the xing screw.
Positions of the linear stem of the actuator
The action of the digital regulator integrated in K282X022 actuator
associates the stem completely retracted to the position of complete
closure (0%) as shown in the picture; the stem completely protruding from
the actuator body is associated to the position of complete opening (100%).

28 way microswitch for actuator addressing
The manual positioning (open ring) of the mixing valve is useful when
starting a system or in order to check the functioning. This operation can
be made with K282 actuator by extracting the apposite jumper on the
board, after removing the upper shell: the rotating potentiometer position
represents the required opening for the mixing valve in this manual state
of functioning. The opening of the direct way from the boiler of the valve
increases by rotating the potentiometer clockwise when Giacomini mixing
valves are used. The stem of the actuator is completely retracted (0%) and
the mixing valve closes the direct way completely (by-pass position), when
the rotating potentiometer is completely rotated anticlockwise; the stem of
the actuator is protruding (100%) and the mixing valve opens the direct way
completely, when potentiometer is completely rotated clockwise.
For the manual positioning:
1) Remove 24 V~ supply to K282 actuator.
2) Loosen the actuator ring xing to valve body and unscrew the actuator
completely.
3) Remove the upper shell of the actuator by removing the 4 xing screws.
4) Extract the jumper placed on the electronic board as shown in the picture.
5) Position the upper shell of the actuator again through the 4 xing screws.
6) Assemble K282X022 actuator on the valve body again.
7) Activate 24 V~ supply. The actuator resets completely until it closes the
direct way completely (0%). The actuator positions at the indicated opening
through the rotating potentiometer.
When the functioning test is nished, follow the instructions and insert the
jumper placed on the electronic board.
Warining.
Manual positioning tests of the valve must be carried out once
the jumper on the electronic board has been extracted and after
assembling again and xing with the 4 apposite screws the upper
shell of the actuator. Do not activate 24 V~ supply before assembling
the upper shell again. The manual positioning of the valve must be
carried out by qualied sta only.
Warining.
The reading of immersion delivery temperature probe is not taken
into account during the manual positioning test of the valve. Make
sure that the delivery temperature is not over or under the safety
limits according to the kind of system. The manual positioning of the
valve must be carried out by qualied sta only.
