KIROS Chronothermostat User Manual
Flush-mounting chronothermostat powered by mains (230 V~), suitable for the control
of heating and air-conditioning systems.
The device, through the relay, acts on the control circuit of the burner or the circulation
pump (heating), or on the control circuit of the air conditioner (conditioning), in order to
guarantee the desired temperature.
The blue backlighting of the display can be switched off if the device is installed in
bedrooms, for example.
The device is supplied with white and anthracite frames and with adapters that allow it
to be installed with the plates of the main civil series.

OPERATING MODE
The device can operate according to the following 3 modes:
Automatic mode
It allows you to use the device
as a chronothermostat and the
temperature regulation follows the "profile"
of the set program. The program profile
assigns one of the 3 temperatures T1, T2 or T3
to each hour of the day.
It is possible to assign a different program to each day of the week.
In the example, the device adjusts the temperature based on the value of:
T2 from 00:00 to 6:00 and from 8:00 to 17:00
T3 from 6:00 to 8:00 and from 17:00 to 21:00
T1 from 21:00 to 24:00
The values of T1, T2 and T3 can be set by the user.
Manual mode
It allows you to use the device as
a thermostat and the regulation
is according to the temperature Tm.
Off mode
It is suitable when long periods of absence are expected.
In this mode the device does not perform any regulation,
however if it works in heating mode, it maintains a
minimum temperature (antifreeze temperature)
to prevent possible freezing of the system.

How the switching delay works
Set a switching delay for a specific hour to maintain,
for the duration of the delay, the temperature value assigned
to the previous hour.
For example, if the program includes:
T2 from 12 to 13
T3 from 13 to 14 with 30 minutes delay
the chronothermostat adjusts the temperature based on the value of
T2 from 12 to 13.30 and
T3 from 13.30 to 14.00
It is possible to set delays of 15, 30, 45 minutes,
independent for every hour of the day.
How to customize the profile of a Px program
• starting from midnight 00:00, press the keys and to assign
to each hour of the day one of the 3 possible temperatures (T1, T2, T3)
and the key to confirm and go to the next hour.
• to enter a switching delay for the selected hour, hold down the key
for a long time. For more information about the switching delay, see
"How the switching delay works"
