FUNCTIONS

The weekly thermostat has the following functions:
• Room thermostat: the internal temperature sensor de-
tects the temperature and, comparing with the set point,
switches ON or OFF the heating request (according the
programmed timings). The temperature sensor is located
on the lower side of the item. In case of cooling mode
selection, the room thermostat works in a opposite way
compared to the heating mode and it switches ON or OFF
the cooling system if connected (when in cooling mode,
only the comfort temperature is selectable).
• Time: on the display it is possible to set and read the time
(weekly hours display mode)
• Programming timing: it is possible to select the desired
ON or OFF heating times. The programming is possible
during one week 24-hours and the minimum time seg-
ment is one hour.
• Status mode: AUTO, PARTY, OFF: Select AUTO mode if
timed ON/OFF period are required. Select PARTY mode
for constant ON (24-hours). Select OFF mode for heating
OFF (summer mode). Note: summer/winter selection is
better to be selected on the main boiler dashboard.
• ADVANCE functions: the pre-programmed heating pat-
tern is advanced to the next ON (or OFF) period
• 3 level temperatures: comfort, economy and frost protection
• Frost protection functionality
• Battery low
• Room temperature calibration
• Heating and cooling mode selection
OPERATING INSTRUCTIONS
At the fi rst installation the thermostat, the time and the day
of the week needs to be set (see encoder paragraph). After
this, a desired thermostat status must be selected (see
the encoder paragraph). When in AUTO mode the heating
request follows the programmed heating pattern and the
desired room temperature selected.
When in PARTY mode the heating request is ON all the
time according the desired room temperature selected.
When in OFF mode, the heating request is OFF all the time
(frost protection is ON).
The thermostat is pre-programmed with a default heating
pattern (see table below); however this can be modifi ed to
suit individual needs (see encoder paragraph)
