according to the programmed times and according to the
set comfort temperature (the ON command is identifi ed by
the fl ame icon). When the heating will be commanded ON
the set-point in the room will be the comfort one. In case of
off programmed times, the set temperature is the "economy
temperature", selectable inside the main menu (16°C is the
default value).
When in OFF mode the heating requested will be switched
on when the room temperature drops under the frost pro-
tection value (default is 5°C); this value can be modifi ed
inside the technical menu.
When in PARTY mode the heating request is permanently
on according the selected comfort temperature that can
be modifi ed any time rotating the encoder and pressing to
confi rm.
ENCODER
The encoder has three functions: selection of the set tem-
perature, set the ADVANCE function and setting the ther-
mostat. If the status mode of the thermostat is OFF, only the
pressing functionality is active; any rotation done does not
generate any modifi cation.
1. Rotate to select the desired temperature and press to
enter.
2. Press once to activate or deactivate the ADVANCE func-
tion. Use to "advance" the heating to an ON or OFF period.
3. Press for 3 seconds to enter menu. Rotate to scroll
through the menu choosing between status mode, eco-
nomy temperature setting, time of day, day of the week,
programmed times day by day, technical menu (PL) and
exit. Press again to modify selected item.
Status mode: rotate to change the thermostat mode
between AUTO, PARTY, and OFF, press to save. The press
from status mode automatically escapes from menu.
Economy temperature ECOt: Rotate to select the desired
economy temperature and press to enter. This temperature is
used when programming time is OFF in AUTO status mode.
Time of the day: rotate to change the hours, press to save.
Move to minutes; rotate to change minutes, press to save.
Day of the week: rotate to change the day, press to save
Programmed times day 1-7: rotate clockwise to set hour
ON, rotate anticlockwise to select hour OFF. Clockwise and
anticlockwise rotation move ahead the time. Press to save.
Rotate clockwise to move to the following day. It is possible
to program together days 1...5 and days 6-7 with the same
pattern in a single operation.
PL: rotate to select the password value, press to enter in-
side the technical menu. Rotate to select the parameters:
01 = calibration of the temperature sensor, 02 = frost pro-
tection temperature selection, 03 = hysteresis OFF value
selection, 04 = hysteresis ON value selection, EHIt = es-
cape from technical menu. (for technical menu see dedic-
ated paragraph).
Exit: escape from main menu.
INSTALLATION AND OPERATING INSTRUCTIONS
Unlike the conventional thermostat, this control separates
the function in two units. The receiver serves for wiring con-
nections and heat on/off control. The transmitter serves as
the user interface and for temperature sensing/control. The
two units are linked by radio frequency (RF). The RF com-
munication is only in one direction from the transmitter to
the receiver, therefore the transmitter does not receive any
feedback from the receiver, no alarm of missing communic-
ation is visible on the transmitter display.
