k) The ON / OFF signal will then be repeated every 20 minutes (the 20-minute in-
terval has been chosen to extend battery life)
l) Reset the setpoint according to f) and g)
m) Press to reset the operating mode to the required position
The receiver's readiness to learn is a maximum of 25 minutes. If no signal is received
from the transmitter during that period of time, repeat steps d) through m) above.
The control mode can be changed via the menu-driven heating engineer settings.
If the room temperature displayed does not agree with the room temperature effectively
measured, the temperature sensor should be recalibrated (refer to «Calibration of sen-
sors»).
