Automatic Bypass Valve
18
The Mitsubishi Electric Pre-Plumbed Slimline Cylinder has a spring differential automatic bypass valve fitted as
standard between the primary flow and return.
This serves two purposes; it allows for the minimum flow rate of the Ecodan
unit to be maintained and hence
®
eliminates the possibility of high pressure or temperature faults due to insufficient flow rate. It will also ensure
that in the event of a pump overrun occurring when the demand for heating or hot water has been satisfied, that
the primary circulation pump (heat pump flow) is able to bypass the zone valves and hence no pump damage
will occur.
The illustration below shows the position of the automatic bypass valve on the cylinder. It is important that this
valve is set so as it opens at the minimum flow rate achieved for the Ecodan
unit in question.
