Buttons and functions

6.  Connect the timer to your tap using the ¾

 tap connector or by 

using the ½

-adaptor, if needed. 

Note! 

Do not tighten too hard, 

as the coupling seals can be damaged by over tightening.

7.  Connect the irrigation hose to the hose coupling (7).

Operating instructions

Note:

 The timer is only designed to be used with cold water at 

a max pressure of 6 bar (90 psi). If your water pressure is higher, 
then a pressure regulator must be used together with the timer.
1.  Set the [ FREQUENCY ] to the desired irrigation interval, from 

once an hour to once a week.

2.  Set the [ RUN TIME ] to the desired irrigation time, from 1 min to 

120 min.

3.  Turn on the tap. 

Note: 

Irrigation will start after the time 

interval [ FREQUENCY ] you have set. So if you have set the 
[ FREQUENCY ] to 1 hour then irrigation will begin one hour after 
you input the setting and then irrigate once every hour thereafter.

4.  If the [ RUN TIME ] setting is set to 

ON

 the water will be allowed 

to flow constantly. If the [ RUN TIME ] setting is set to 

OFF

 

the water will be shut off constantly.

Irrigation setup examples

Set the [ FREQUENCY ]  setting  to

.

•  To set your watering settings to twice a day: 

Set the [ FREQUENCY ]  setting  to 

12

.

•  To set your watering settings to every other day: 

Set the [ FREQUENCY ]  setting  to 

48

Week

.

Using the delay control to set the irrigation 
start time

You can delay the irrigation start time in 1-hour intervals from 
1 to 12 hours by depressing the irrigation control (4). Each press 
corresponds to 1 hour of delay.

Example: 

If you input your settings at 1:15 pm and you want your 

irrigation to start at 3:15 pm then you would press the delay control 
twice (1 press = 1 h delay).

Battery status indicator

Battery status (3) indications:
•  Flashing: Functioning normally but the batteries are low and 

should be changed as soon as possible.

•  Solid: Batteries will soon become flat and water flow will be 

shut off.

•  Flashing-solid-off: Batteries are completely flat.

Note:

 Inserting new batteries does not trigger the battery indicator 

to activate or shine. The battery indicator only indicates low and 
extremely low battery status, not when batteries are new or have 
been completely flat for a time.

Care and maintenance

•  Clean the timer using a lightly moistened cloth. Use only mild 

cleaning agents, never solvents or corrosive chemicals. Keep all 
water away from the battery chamber as water can leak in and 
cause short circuiting.

•  Never mix old and new batteries or rechargeable batteries with 

non-rechargeable batteries.

•  Never try to open the housing or modify the timer in any way. 

This can lead to irreparable damage.

•  Disconnect the timer from the tap and remove the batteries if 

the timer is not to be used for an extended period.

timer does

setting is set to 2 hours.
