THERMOPROGRAM
The TH124 THERMOPROGRAM programmable
thermostat is designed to ensure ideal tempera-
ture conditions at all hours of the day.
It takes only minutes to install, because it is con-
nected to the heating/cooling plant simply by
means of two wires.
Three LR6 type AA 1.5 V alkaline batteries are
used to power the THERMOPROGRAM for over
two year.
The termostat is extremely easy to program by
means of cursors; a spacious display enables
you to see the time, room temperature and all the
settings.
The temperature threshold can be set at ±0.1 °C
or ±0.9 °C.
The THERMOPROGRAM can generally control
both heating and cooling plants and it can repla-
ce any previous on/off thermostat.

The temperature differential can be set from ±
0.1 °C to ± 0.9 °C.

9 - HOLIDAY PROGRAM
In the event you want a set temperature for a few
hours or a few days (for example, to maintain a
comfortable temperature for longer when you
have unexpected guests, or when wanting a
frost-protection temperature while you are away
in winter), the HOLIDAY PROGRAM can be
activated in timed MANUAL mode. Once you
have set the desired time, the device starts a
countdown.
When it reaches zero, the unit switches from
MANUAL to AUTOMATIC mode, resuming the
set programme.
Programming in hours
9.1 - Select MANUAL mode and set the desired
temperature (fig. 26).
9.2 - Press button (fig. 27).
The message h01 comes up on the display in
place of the current time.
9.3 - Press the button (fig. 28) until you reach
the desired number of hours, which can range
from 1 to 99.
The countdown of the hours also includes the
