Signal strength test – step 1
• Hold the CS92A transceiver
(without mounting plate and sensor)
approximately 1 metre from evotouch and
check the signal strength is high (>2). If
so, move to step 2.
• If the red light repeatedly flashes
0.1s on / 0.9s off without pausing, this
means CS92A is not bound to evotouch.
Go to "How to bind CS92A to evotouch",
follow the instructions there and after
binding is complete, return to the signal
strength test.
Signal strength test – step 2
• Whilst staying in signal strength test
mode, take the CS92A transceiver to the
preferred location. Wait for 10 seconds
and check the signal strength > 2. If so,
the CS92A is ready to mount.
• If the signal strength is < 2, re-position
the transceiver within the local area
+/– 1m to see if the signal strength
improves. If this fails, you may need
to re-position the CS92A transceiver
completely and extend the cable to the
sensor element.
Exit signal strength test
• Exit signal strength test by pressing the
CS92A button again. CS92A will time
out of this mode after 10 minutes, but
may indicate a sensor fault if the sensor
element is not connected within this time
period.
evotouch RF test
The signal strength can be displayed at the
evotouch, too.
• Go to the evotouch menu, select RF TEST
HOT WATER and follow the instructions
on the screens.
• Press the button of the CS92A briefly to
activate the test mode.
• Press the NEXT button on the evotouch.
• The signal strength is indicated on the
evotouch controller.
The signal strength can be EXCELLENT,
GOOD, POOR or NOT RECEIVED.

conditions will be indicated on the evotouch.
It is possible to view the CS92A status by
pressing the button on the transceiver box.
The lights underneath this button will provide
feedback as shown in the table.
