How do I enter parameter setting mode to change the control behavior?

Press LEARN on the rear of the transmitter for 5 seconds until 'P01' appears on the display. Press LEARN again so the parameter value flashes, then adjust it using the setting knob, and press LEARN once to confirm. Exit by rotating the knob clockwise to 'End' and pressing LEARN once. Note that the thermostat automatically exits parameter setting mode one minute after the last action. (Page 4)
