Testing the RF transmission range
1. Ensure the receiver is correctly wired to the
output, and that it has a mains supply
(indicated by a continuous red LED at the
receiver)
2. The transmitter display shows the current
actual temperature. Press the UP button until
the set temperature is higher than the actual
temperature.
3. After a few seconds the heater/cooler on icon is
shown – it appears as a rotating symbol above
the P number.

be On.
5. If the LED is not On, move the Transmitter
closer to the Receiver.
6. Press the DOWN button to reduce the set
temperature below the current temperature to
turn off the demand from the receiver. The
rotating symbol will disappear, and the green
LED will go Off.
