Installation Instructions
Mounting The Controller
This controller unit is an INDOOR MODEL and MUST not
be exposed to rain or water ingress.
(If the controller needs to be outdoors, you can purchase
a HOLMAN outdoor weatherproof box, P/N COBOX, to
mount the controller inside.This box is available from
your irrigation supplier.)
Install the controller near a 240V AC mains outlet,
preferably located in a house, garage or other covered
area. For ease of operation, eye level placement is
recommended.
Drive one #8 screw into the wall, leaving about 4mm of
the screw exposed. If necessary, use a toggle bolt or
masonary shield.
Hang the controller from the key slot located in the back
of the case. Make sure the head is properly seated inside
the controller case. Additional screws may be inserted
through the holes in the lower corners of the controller
case.

WARNING
1 All electrical work must be carried out in
accordance with these instructions following all
applicable Local, State and Federal codes, or

Other Features
Rain Off Mode
To stop the automatic watering cycles during winter, turn
the dial to the Off position. The word “Off” will appear in
the display. This means the automatic programs will not
come on, but the programmed information is still
retained in the memory. To reactivate the automatic
schedule, turn the dial back to the Auto Run position.
NOTE: If a rain sensor has been connected, the stations
set to rain sensor control, will be turned OFF
automatically, when the sensor is wet.
Water Budgeting
The automatic station run times can be adjusted by
percentage as the seasons change. This will save time
and money as the run times can be adjusted quickly in
spring, winter and autumn to reduce the amount of water
used.
Ensure that the dial is in the Auto Run position and then
press the
back
and
next
buttons simultaneously.
The display will show:
Displayed is the word “Budget” and “100%”.
This represents the current automatic watering run times
as being 100%. The percentage budget can be set in
25% increments from 25% up to 150%.
Example: 50% reduces watering by half.
To adjust in 25% increments, use
or buttons.
To return to the clock press the
back
and
next
buttons
simultaneously. The display will show the word Budget to
indicate that the water budgeting feature is in use.
