Gate valve for flow adjustment on open
by-pass
If multiple heat emitter circuits are installed, operating
at diff
erent flow and return temperatures (such as
under floor heating and standard radiators), a mixing
valve must be used on low temperature circuits to
prevent high temperature water from entering the
under floor heating manifold.

Note
NOTE: If ANY of the zones are using an externally
controlled circulating pump, the open by-pass must
be fitted.
NOTE: Fill & Flush connections are not supplied
