MIXER CONNECTION
During assembly works for mixer
servomotor pay attention not to
overheat the boiler. This may
happen when there is a limited
flow of water from the boiler. It is
recommended
to
check
the
location of valve in maximum
opening before starting work, to
ascertain heat acceptance from
the boiler by opening the valve to
maximum.
The
controller
cooperates
only
with
servomotors of mixing valves equipped with
end switchers. Using other servomotors is
forbidden. Servomotors with full circle scope
of 30 to 255s can be used.
