Signal
Hold the Smart Sensor in your desired location. Press and hold ‘/\’ arrow button for 5 seconds. The Smart Sensor will enter signal strength testing mode.

A sweeping LED will be displayed whilst the signal detection is in progress. If a signal is detected, the strength will be measured from 1 - 5 by lighting LEDs accordingly. To work effectively, the signal should be a minimum of two LEDs.

Central Heating and/or Hot Water outputs
Press and hold both keys on the receiver for 5 seconds. '1 ' and the ‘WiFi’ light will slowly flash. Cycle the left key until ‘1,2,3 and 4’ all flash at the same time, then press the right key.

The unit is now in test mode and either ‘CH’ (2ch series) or ‘1’ (4ch series) will flash.

• Use the left key to switch between zones (CH / HW or 1 – 4).
• Use the right key to switch the zone On and Off (The flame will light when the zone is on).
• You can exit this mode by pressing and holding both keys. Test mode will automatically exit after 10 minutes with no key presses.

If the boiler does not fire up when testing a hot water zone, you may already have a full tank of hot water. In which case, temporarily increase the cylinder stat to max for this test
