FREQUENTLY ASKED QUESTIONS
What are the features required for the Bluetooth®product to
work? A smartphone or tablet running Android 4.3 or greater with
Bluetooth Smart 4.0 or greater. An Apple iPhone or iPad running
iOS 9.0 or greater with Bluetooth Smart 4.0 or greater.
Why does my station not start? On each station, you must enter a
duration and assigned it to a program (A or B or C). If several stations
are assigned to the same program, they will start one after the other.
Why does my Program B not start? If the start time of Program A
is the same time entered in Program B, the two programs will be
executed one after the other in the order Aand then B.
What is the output P? You can connect a master valve or a pump
on the Poutput. The output will automatically start 2 seconds before
each station and during the watering of each station.
What are the S outputs (Yellow Wires) of the programmer?
You can connect a Rain Sensor on the Soutputs by cutting and
stripping the yellow wire.
How does the rain sensor work? When the sensor is connected
to the yellow wire (see wiring step for each model), it affects all 3
programs. If it rains and the rainsensor is active, programs A or B or
Cwill not start. It is necessary to wait until the sensor has reset before
irrigation will restart. Manual control «All stations» is not affected by
the rain sensor. You can manually operate the system even if the rain
sensor is activated.

FREQUENTLY ASKED QUESTIONS - CONTINUED
What is the Water Budget? The Water Budget adds or subtracts a
% of time to the duration of each station. It is typically used when
changing seasons (for example summer to fall or spring to summer).
Example: If you entered Station 1 = 1h on Program A and Station 2
= 0h30 on Program A, then enter a Water Budget 120 % for Program
A. When the Program A starts, the stations 1 and 2 will be increased
by 20%, (example: 1h12 for Station 1 and 0h36 for Station 2).
How can I restart the initialization procedure (for example: change
the router acces point)? To reset a device or restart an initialization
procedure, short circuit the 2 pads of the battery pressure (remove the
9V battery and reverse the terminals OR place a metal object such as
a screwdriver over both terminals) for 30 seconds minimum.
If my device does not have a battery, do I lose programs?
The BL-KR has non-volatile memory that stores programs even if the
controller loses power.
I would like to reset all programming information on my device.
How do I do this? If you want to reset the controller, launch the
K-Rain BL App, select the controller you want to reset, and then open
the P Parameters and select «Clear programs and durations».
