5 secs
Signal Strength = 2
evotouch measures the strength of the
CS92A signal every 5 seconds and will
communicate this to CS92A as a number
between 0 and 5. CS92A will then indicate
this number by flashing its red light a
number of times in succession, followed by
a pause of between 2 and 4 seconds. The
number of flashes is equivalent to the signal
strength number.
A signal strength > 2 is recommended to
ensure reliable communication.

Troubleshooting
This section gives suggested answers to typical problems that installers may encounter:
Problem Solution
Domestic hot water not available In case of a communication failure the relay module for
domestic hot water will be switched off.
Check RF communication.
Check the hot water sensor: Press CS92A button and the red
light blinks 0.5s on / 0.5s off. (Note: the light will switch off
after approx. 1 minute to save battery power.)
The batteries of the hot water
sensor are discharged
The evotouch will display a message that the batteries of the
hot water sensor are discharged.
It is important to change the CS92A batteries as soon as it
is displayed on the evotouch. Reduced battery power might
affect the RF signal strength and have an impact on RF
communications.
Check battery status on the CS92A: Press CS92A button
and the red light gives a short flash every second 0.1s on /
0.9soff. (Note: the light will switch off after approx. 1 minute
to save battery power.)
Communication loss Loss of communication will be indicated on the evotouch or
the actuators.
Check the RF communication between evotouch and the
actuators and sensors.
If there is no communication try to bind the device again.
If this does not resolve the problem, check the RF path
between the two devices and reposition any object that may
be blocking the RFsignal.
