• If binding was successful CS92A will exit binding mode and both lights will switch off.

• If binding was unsuccessful, repeat binding procedure.

CS92A signal strength testOnce CS92A is bound to evotouch, the signal strength test allows the transceiver to be positioned in the best possible location for signal reception.

Activate signal strength test on the CS92A transceiver

Green light (under button)

Red light (under button)

• Press the CS92A button once.• The green light should come on. If it

doesn’t, reinsert the batteries and try again.

• With the green light on, the red light should start to flash to indicate the status.

Signal Strength = 5

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.

Configuring CS92A

ENG

LISH

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 testThe 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.

TroubleshootingThis 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.
