Control unit – Sensor transmitter pairing
If the error message [ No Sensor Signal ] is displayed at the bottom of the home screen, this
means that control unit-sensor transmitter pairing has already taken place but no sensor
transmitter signal is being received. Reasons for this could be:
• Sensor transmitter is not powered up
• Sensor transmitter or controller has been changed from the ones originally paired.
A new sensor transmitter can be paired with the Apollo GEM controller by going to set-up screen
6 (installer menu) and changing the wireless parameter from “PAIRED” to “START PAIR”
After 30 seconds set-up mode will exit and the pairing process will begin.
Remember to power off and on the sensor transmitter to activate the “Find me” signal.

(Installer Menu Page 1)
change wireless parameter
to "START PAIR" to pair new
controller/transmitter
When the system is paired continue:
6. Briefly press the "Boost" button to start boost mode.
This will check that:
b) The heater is working and
c) The power measuring system is working correctly.
Check That the display shows "Boost 1 ON 60 mins" and that the measured import
power has increased by approximately the heater power e.g. 3KW.
(If exporting check the export power decreased by the heater power)
If Boost mode remains on and the power reading is as expected then everything is working.
Press the boost button four more times to turn off boost mode.
The system is now ready for operation.
If boost mode will not stay on but reverts back to optimising after a few seconds, see the
section above - "If Boost mode will not stay on".
