Extend Facility
The mains electricity supply must be
ON
and the keyswitch set to
Run
before using the facilities detailed on this page.
The unit is supplied with an extend facility to allow additional periods of
operation without disturbing the set programme.
The extend period is set to 1 hour, but at the time of installation this can
easily be altered.
To alter the extend period:
Insert the key and turn to
Set Programme
Press
‘Extend’
and the display will show the extend period.
Press any of the numerical keypads to alter the extend period to 1 to 8
hours or 0 to disable the function (display will show
‘nil’
), or 9 for a constant
extend period (display will show
‘con’
).
Once the required extend period is displayed, press
‘Enter On’
and the
new extend period will be stored.
Using the Extend Function:
With the keyswitch set to
Run
, pressing
‘Extend’
activates the additional
period of operation.
If the key is pressed when the output is
‘Off ’
it will switch on immediately
and will automatically switch off after the extend period has elapsed. The
associated red indicator light will be illuminated throughout the extend
period.
If the key is pressed when the output is ‘
On
’ the current ‘
On
’ period will be
extended by the length of the extend period. The red indicator light will
be illuminated until the output is switched off .
The Extend facility may be cancelled at any time by pressing the key
again, when the indicator light will go out and the unit will revert to the
set programme.
Crop Facility
This facility enables a current
‘On’
period to be cancelled without having
to disturb the set programme.
If the
‘Crop’
key is pressed when the output light is illuminated it will
switch the output off until the next programmed
‘On’
event. During
the remainder of the present
‘On’
period the associated red light will be
illuminated and the output light will be off . The programme event light
will remain unchanged.
Pressing the
‘Crop’
key again will cancel the Crop facility and restore the
unit to the set programme.
Note
: Pressing the
‘Crop’
key when the output is already programmed to
be off will have no eff ect.
BATTERY RESERVE
The unit does not rely on the internal battery in order to work satisfactorily
providing the mains power supply is connected to the unit. The battery is
fi tted purely to memorise the Time of Day and selected Switching Times
in the event of a power failure or disconnection of supply.
When the unit is fi rst connected it will require a minimum of 24 hours to
become suffi
ciently charged in order to perform this memory function.
Thereafter the battery is automatically recharged.
If the mains power supply is lost, for any reason, the display and lights on the
unit will go out and the output will be switched off . The battery will maintain
the memory for a period of up to 3 months during this condition. When
the power supply is restored, the unit will automatically switch on again
and resume the set programme without any resetting being necessary.
