With this in mind, do not keep the “SET” and “DAY” buttons of the
thermostat depressed simultaneously or the “M/A” button of the
receiver unit depressed without any reason after the two units
have been tuned successfully.
10.3 Transmission distance inspection
With the help of the “TEST” button you can check whether
the two units are within the transmission distance of the
radiofrequency connection. To perform the test, press the
“TEST” button for approximately 3 seconds. Following this, the
thermostat will send, alternating every 5 seconds, switch-on
and switch-o control signals to the receiver for 2 minutes (the
signal appears and disappears alternately on the display).
When detecting the ON and OFF control signals, the red LED
light on the receiver unit switches on and o, respectively.
When the receiver unit fails to receive signals sent by the
thermostat, then the receiver unit is outside the transmission
distance of the wireless (radio-frequency) transmitter, thus
they have to be placed closer to each other.
