With the 1.3.3 update for Apple iOS devices and 1.3.4 for Android smartphones e tablets, we introduced several new functionalities, among which the chance to personalize the settings for hysteresis and offset parameters (to perfectly calibrate Rialto Smart Thermostat).

Before such update, hysteresis parameters were fixed at 0,1° and the temperature detected by the thermostat, calibrated during production, wasn’t adaptable.

What are they?

Changing the values of upper and lower hysteresis, the temperatures which trigger the functioning of the thermostat for heating (winter mode) and cooling (summer mode) can now be personalized for each users’ need.

Winter mode (heating)

⤒ Higher hysteresis
It’s a delay in the switching off of the heating: the thermostat switches off the heating when it reaches the SET point plus the value of higher hysteresis.

↥ Lower hysteresis
It’s an anticipation in the switching on of the heating: the thermostat switches it on when the ambient temperature is equal to SET point minus the value of lower hysteresis.

Summer mode (cooling)

↧ Higher hysteresis
It’s an anticipation in the switching on of the cooling system: thermostat switches it on when the ambient temperature is equal to the SET point plus the value of the higher hysteresis.

⤓ Lower hysteresis
It’s a delay in the switching off of the cooling system: thermostat switches it off when it reaches the SET point minus the value of the lower hysteresis.

For instance:

  • with SET point 20°, the thermostat will switch the heating on at 19.8° (lower hysteresis 0,2°) and it will switch it off at 20.1° (higher hysteresis 0,1°).

 

  • With SET point 22°, the thermostat will switch the cooling on at 22.1° (higher hysteresis 0,1°) and it will switch it off at 21.8° (lower hysteresis 0,2°).

Offset calibration parameter allows to calibrate the temperature detected by Rialto Smart Thermostat in order to have a customized temperature detection:

Value set by the user will be addes (when positive) or subtracted (when negative).

Customizing these parameters, consulting and analyzing your system’s operating chart and adjusting daily chrono program, you will definitely improve usage of your heating/cooling system and reduce energetic bills!

For instance, the chart below shows how to keep an ambient temperature close to the SET point wished, with a 0,1° higher hysteresis and 0,2° lower hysteresis.
