7.5.3.1. On/off adjustment
In on/off mode, the thermostat measures the room temperature once a minute and controls the system according
to the following logic:
ON relay
SET-dIF SET
OFF relay
Temperature
up
ON relay
(SET+dIF) SET
OFF relay
Temperature
up
heating mode cooling mode
SET is the setpoint and dIF is the differential or hysteresis (this is useful to avoid continuous switching on and off
which could be detrimental to the system when the setpoint is reached).
7.5.3.2. Proportional adjustment TPI (1) (warm-up only)
In heating mode, proportional control is also available in addition to on/off control to allow more precise control
in order to obtain a constant temperature.
This setting requires you to specify two parameters:
the band, which develops symmetrically to the right and left of the setpoint. It can assume values between
0.5°C and 5°C. Outside these values, the heating will always be on (if room temperature < (setpoint - band)
or always off (if room temperature > se band);
the control period which is the duration of the control cycle (on time + heating off time) and can take values
of 10, 20 or 30 minutes.
During operation, at the beginning of the control period, the thermostat measures the room temperature (TA)
and compares it with the setpoint. According to the difference, the switch-on time (and consequently also the
switch-off time) within the next control period is calculated. The closer the measured temperature is to the
setpoint - band value, the more the on time will be predominant over the off time. Conversely, the closer the
measured temperature is to the se band value, the more the off time will be predominant than the on
time

After the control time (10, 20 or 30 minutes), the thermostat compares the room temperature with the setpoint
again and updates the on/off times for the new period.
The proportional control performance is subject to the correct choice of parameters.
Select the setting band value as follows:
broad band (5°C) for systems with high thermal gradient (

) ;
narrow band (0.5°C) for systems with low thermal gradient
(

)
.
Select the value of the setting period as follows:
10’ for low thermal inertia systems (fan-coil)
20’ for medium thermal inertia systems (aluminium radiators)
30’ for high thermal inertia systems (cast iron radiators)
