2.2 Setting current day and hour
Press the “• DAY” button. At this time only the serial number of the day will flash
on the display of the thermostat and the hour and minute values can be seen.
Using the large• ........or........button on the front panel of the device, set the
serial number of the current day (Monday 1; Tuesday 2; Wednesday 3, etc.).
Press the “• DAY” button again. At this time the number indicating the day
stops flashing and becomes visible continuously while the numbers indicating
the hour will flash on the display.
Using the large• ........or........button on the front panel of the device, set the
hour value of the current time.
Press the “• DAY” button again. At this time the numbers that indicate the hour
stop flashing and become visible continuously, while the numbers indicating
the minute will begin flashing.
Using the large• ........or........button on the front panel of the device, set the
minute value of the current time.
When you wish to modify settings, please press the “• DAY” button again
to return to the initial settings. If you wish to finish settings, acknowledge
them by pressing the “SET” button. At this point adjusted data are recorded
and the device goes back to the main screen. (After approximately 10
seconds, the settings are automatically acknowledged and the device
goes back to the main screen).
2.3 Setting switching sensitivity
According to factory default settings, the switching sensitivity is ±0.2°C
(the display indicates this setting with symbol “S:1”) which can be modified to
+0/-0.2°C (the display indicates this setting with symbol “S:2”). The required
switching sensitivity can be set by pressing ”DAY”, “COPY” and the large
........or........buttons one after the other, after going back to the main screen by
pressing the “SET” button. Setting “S1” (±0.2°C switching sensitivity) or “S2” (+0/-
0.2°C switching sensitivity) is acknowledged by pressing the “SET” button. (After
approximately 10 seconds settings are automatically acknowledged and the
device goes back to the main screen). Pressing the “RESET” button the switching
sensitivity is reset to factory default setting, i.e. to ±0.2°C level (“S1”).
The ±0.2°C switching sensitivity ensured by factory default settings (the
display shows symbol “S:1” for this setting) is primarily recommended for
radiator-based central heating systems (e.g. where plate radiators are
installed) with low thermal inertia, while the +0/-0.2°C switching sensitivity
(the display shows symbol “S:2” for this setting) is recommended to control
heating systems with high thermal inertia (e.g. underfloor heating).
2.4 Activation of the pump protection function
Under the factory default settings, the pump protection function is inactive.
It can be activated or switched off by pressing “DAY”, “PROG” and the large
........or........buttons one after the other, after going back to the main screen
by pressing the “SET” button. Setting “HP:OFF” (switched-off) or “HP:ON”
