There are three Flow Alerts:
HIGH FLOW
*
,
LOW FLOW
and
FLOW OK
and these relate to the flow through the
selected valve.

*
For static balancing valves,
HIGH FLOW
conditions would normally mean that the flow through the device is in
excess of recommended maximum flows as quoted in BS7350. For automatic balancing valves,
HIGH FLOW
conditions would normally mean that the maximum working
Δp
for the device has been exceeded. The
presence of the
HIGH FLOW
alert on the screen will almost certainly be accompanied by significant system
noise.
Note: if Flow Alerts are Enabled when working on an unstable system, the displayed alert may change, quite
frequently, between the HIGH / LOW / OK options and this may only serve to
impede – rather than assist – the
commissioning process. Hence, it is strongly recommended that Flow Alerts remain Disabled when work
is being carried out on an unstable system, or on a system that has little regulation.
Default = 5 min
The Backlight Timer sets the period of time after which the backlight will turn off after a period of inactivity.
A short time will preserve battery life.
