Smart
Shutdown
Mode
‘Smart Shutdown’ is a mode that your controller will enter to minimise
damage. It can be activated when the temperature at the ROOF sensor is
less than -40°C/-40°
F
or more than 142°C/288°
F
.
This may occur because:
there is a fault in the sensor wiring, OR
the Solar Collector has reached a very high temperature.
If Smart Shutdown Mode is activated, you will see SSd on the display as
shown on the screen below.
The ROOF sensor temperature may reduce to a safe level by itself and the
uniit will return to normal operation. ‘SSd’ will no longer appear on the
display.
This is a normal condition and it is not necessary to contact your installer or
maintenance technician unless ‘SSd is on the display for more than 12 hours.

SSd
on the display shows the controller is in Smart
Shutdown Mode – i.e. there is a fault condition.
When
SSd
is displayed, the
ROOF, TANK
or
INLET
will be on or flashing to indicate which
sensor is faulty. In this case, a faulty
ROOF
sensor has been detected.
