Cool down period
Once the water availability stage has timed out the system will
proceed into automatic “Cool down”. The system will perform a
series of tank drain downs and introduce cold RO permeate into the
distribution loops until the return temperature on the system falls
below the “maximum service temperature” setting. The factory
default for this can be found in Section 6.10. On reaching this
temperature the system automatically disconnects itself from the
loop(s) and re-introduces the RO unit(s).
Drain in Operation
Following the Cool down period the tank drain valve will remain
open until the tank level falls to zero at which point the unit will
return to
STANDBY.
To ensure that the tank remains empty during
STANDBY
the drain valve will open
for 5 minutes every 2 hours.
Standby
STANDBY
will be displayed to indicate that the unit is “healthy” and
waiting for the next heat disinfection routine to initiate.
Remote Light
A four tier remote light is available to clearly and easily show the
operational state of the Heatsan.
