ALIBRATION
It is possible to calibrate the
transmitter temperature sensor by entering the 02
parameter. On the display will appear only the
temperature. Use the encoder to increase or
decrease the temperature. Press the encoder 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 that will be used as
master. This operation is suggested only if the
thermostat is fixed in a non-appropriate position,
therefore it is necessary to modify the value on the
display to be according the real room temperature.

ROST PROTECTION TEMPERATURE
The weekly
room thermostat has an internal anti-frost function
that switches on the boiler (only when the boiler is
properly set to allow the room thermostat to
activate/deactivate the boiler, i.e. boiler in winter
mode) if the room temperature drops below the
selected temperature. This function is active all the
time whatever the programming time or the set
temperature. By entering the 03 parameter it is
possible to adjust the frost protection temperature:
the factory setting is 5°C, the 03 parameter can be
adjusted between 3°C and 10°C. the frost
protection selected temperature becomes the
minimum settable value for the economy
temperature (inside the main menu).

ARNING
! This anti-frost protection is not intended
to be the main control to protect the entire heating
system and the boiler during a freezing period.

YSTERESIS
OFF
The value selected with this
parameter indicates when the heat request is
stopped. The factory setting is 0,4°C, values range
between 0,0°C and 2,0°C. Heat requests switch
OFF when the room temperature reaches the
room target temperature plus the hysteresis OFF
value.
04
H
YSTERESIS
ON
The value selected with this
parameter indicates when the heat request is
activated. The factory setting is 0,2°C, values
range between 0,0°C and 2,0°C. Heat requests
switch ON when the room temperature drop below
the room target temperature minus the hysteresis
ON value.
