    21 Parameters: basic and advanced Thermostat operation is governed by a series of parameters that can be activated/deactivated and regulated by the user. Depending on the settings defined via the app, these parameters may be enabled or disabled, enabled for Administrators only, accessible or not accessible locally. Local access to the basic and advanced parameters must be enabled by an Administrator via the app.
