Exit from manual
The AUTO/MAN button allows the user to switch between
automatic and manual operating mode as required.
To safeguard against leaving a system indefinitely in
manual mode, an automatic exit has been included. This
will return the operating mode from manual to automatic
five minutes plus the selected safety lockout time after the
last manual mode operation. Relevant manual mode
operations are pressing the lower button and operation of
an output relay.
Models without the automatic exit from manual are
available.

Self Test
At reset and every ten minutes in operation, the NOVAR
executes an internal hardware check for correct
functioning. During this process, the model number will be
displayed.
If the unit fails this self test, the IND and CAP LEDs are
toggled and the alarm relay (if fitted) is also “flashed “ in
time with this.
