Actuator on/off (SD20)
Application
The electrical actuator in combination
with the 3-way valve (TRV20/25) is used
for regulating the heat supply to the
unit. It's function is to open or close the
valve (on/off). The actuator will open
the valve when power is applied. The
actuator is "soft closing" just to avoid
noise and pressure blow in the pipe
system.
The electrical actuator can be
mounted and rotated after that the valve
has been installed.
For regulating the actuator in
combination with valve complement
with appropiate thermostat.
Mounting
Never use the actuator as a mounting
lever. Make sure the actuator is free
of thermal insulation connections and
leave at least 20 mm clearance above
the actuator for mounting purposes
according to the figure below.
Technical specifications | SD20
Application
The bypass valve is used when a small
amount flow of water should pass by
the unit at all times. The purpose of
this is that the water should always stay
hot in the watercoil, in cases when a
door opens and a quick heat supply is
needed.
This kind of valve has the dimension
DN10 (3/8").
When mounting the plug inside the
valve must be screwed entirely at first
and then screwed back a whole lap.
In cases where the distance between
inlet and the unit is far away, open the
plug even more by screwing the plug
backwards.
