BRIO
2000 - MT Automatic pump controller with timer
FEATURES
The
BRIO 2000M controller is designed to automate the
operation of an electric pump by sensing a drop in pressure in the
system (opening a tap or valve) . The controller will turn off when
the tap or valve is closed.
The
BRIO can be used in conjunction with shower pumps
in installations where there is a “negative head”, i.e.
the shower head is above the water level in the cold storage tank,
and also where the pumps are supplying several outlets at once e.g.
body jets, or domestic water supplies.
The
BRIO comes complete with a pressure gauge, which
allows the starting pressure value and system pressure to be checked.
The unit will also protect the pump from dry running if the water
supply should fail. The new 2004 version has a built-in timer which
will automatically try to reset itself every 30 minutes in the event
of a previous shut down due to a lack of water.
BRIO
controllers are suitable for use in pairs to operate shower pumps
on hot (max 65oc) and cold supplies, subject to the maximum electrical
load (12 amps) not being exceeded, The BRIO is
designed for use on clean water. If there is the possibility of
sediment, a suitable filter should be installed before the unit.
