PAR. DESCRIPTION
CALIBRATION. It is possible to calibrate the
transmitter temperature sensor by entering the
P03 parameter. On the display will appear only
the temperature. Use the encoder to increase
or decrease the temperature. Press the push
button to enter the new value. From now the
transmitter uses the new value as current room
temperature. Please note that for the calibration
it is necessary to have a second thermometer
P03
that will be used as master. This operation is
suggested only if the thermostat is fixed in a
non-appropriate position, therefore it is neces-
sary to modify the value on the display to be
according the real room temperature.
WARNING! Avoid to touch thermostat casing
especially near the temperature sensor during
the calibration in order do not alternate the val-
ues with the hands heat.
