The RAV11… is a two-position controller providing PID control. The room temperature is
controlled through the cyclic switching of a regulating unit.
The controller is supplied with an active self-learning mode, which enables it to auto-
matically adapt to the controlled system (type of building construction, type of radiators,
size of rooms, etc.). After a certain learning period, the controller optimises its parame-
ters and then operates in the mode it has learned.
In exceptional cases, where the self-learning mode may not be adequate, it is possible
to choose between PID 12, PID 6 or 2-Pt mode:
Switching cycle of 12 min for normal or slow controlled systems (e.g. massive building
structures, large spaces, cast-iron radiators, oil burners).
Switching cycle of 6 min for fast controlled systems (e.g. light building structures, small
spaces, plate radiators or convectors, gas burners).
Pure two-position control with a switching differential of 0.5 °C (±0.25 °C) for very diffi-
cult controlled systems with considerable outside temperature variations.
