+ Integral) regulation is implemented. The smaller the integration time, the greater the influence of
the integral action and, vice-versa, the greater integration time the lesser the effect of the integral
action. If the integral is weak or absent, it may not be possible to reach the set-point temperature in
the controlled environment. If the integral action is too strong, it may cause the room temperature
to oscillate. It is necessary to adjust these parameters according to the actual environment where
the system is installed in order to achieve the best regulation accuracy.
Proportional control of the valves is only possible when they are driven by the 0..10V outputs.
Proportional control is not possible when using ON/OFF valves, as they will either be always ON
or always OFF, with a hysteresis value set-up in parameter P19.
The fan may be driven proportionally only when it is in automatic speed mode. The fan speed are
regulated proportionally (P + I) even when using a three speed fan motor.
The space between the three speed stages is calculated dividing the proportional band by three and
rounding down. For example, if the proportional band is set to 2°C (35.6 °F), the space between
stages will be 0.6°C (33.08 °F).
INSTALLER CONFIGURATION
The installer configuration defines how the thermostat functions and may be used to adapt it to the
different types of environments and systems. To access the configuration menu, press the
buttons simultaneously for a few seconds until “Con” (configuration) appears on the screen.
At this point, press the button to scroll through the various parameters, identified by a P and
the respective parameter number, from P01 to P25. Once configuration is complete, the message

The installer configuration consists of two lists of parameters:
- main parameters P01 to P25 (table 1)
- extended parameters C01 to C23 (table 2)
The extended parameters C01-C01-C23 are used for the advanced thermostat settings.
When the display shows “Con” at the start of the configuration procedure or “End” upon completion,
press the
button to access the extended parameters.
