Construction details
Configuration with
SEPCOLL supplied
from right-hand side
Mixing valve
The mixing valve is a three-way model with sector obturator
featuring adjustment and by-pass ports specifically constructed to
obtain equipercentage/linear characteristics. This adjustment
characteristic guarantees the best possible system response to the
various load conditions.
Adjustment port - A
Thermal decoupler
Configuration with
Between the valve body and the actuator there is a polymer thermal
SEPCOLL supplied
decoupler,
from
left-hand which
side contains two stainless steel stems and a central
insulating ring. This prevents the transmission of heat from the
electric actuator to the thermal medium. This prevents
condensation build-up inside the actuator.

Wiring diagrams
1) Extract the clip from the base of the actuator.
2) Remove the circulator protective insulation. Figure (2A)
shows a detail of the correct positioning of the circulator
protective shell.
3) Remove the front of the unit’s insulation. The two half shells
are held together by a strip of Velcro.
4) Remove the front half shell, making the circulator pass
through it. The power cable enters through the hole in the
insulation (pay attention to this detail during the
reassembly procedure).
5) The unit is ready to install. To refit the insulation, perform
the steps in reverse order.
