Troubleshooting

This section gives suggested answers to typical problems that installers may encounter:
Problem
Domestic hot water not available
The batteries of the hot water
sensor are discharged
Communication loss
Solution
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 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.)
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.
