Optivent® System

Optivent® Basic and Plus will give you low operating costs over time

The Optivent® integrated system minimises energy consumption whilst providing a controlled supply of conditioned air to maintain pre-set CO2 levels and a user-defi ned temperature, delivered quietly, without draughts.

The air that we breathe out makes humans the largest source of carbon dioxide (CO2) inside a room. For this reason, the level of CO2 in a room can be used as a reliable indicator of the loading and, as a result, the air quality in a room. An increase in the number of persons in a room also causes an increase in the level of CO2, and conversely the level of CO2 falls proportionally as the number of persons in a room decreases.

Dynamically varying the air flow according to the actual loading, based on temperature, occupancy, CO2 level or a combination of these parameters, brings several advantages.
You can ensure good air quality and a comfortable indoor climate at the same time as you avoid unnecessary ventilation and save energy as a result.

Selecting an appropriate control methodology

Temperature regulation
Suitable for premises with a high occupancy level and a uniform loading.
Via the integral temperature sensor or STRZ-05 external temperature sensor, a pre-set temperature is maintained in the room regardless of the loading.

Occupancy regulation
Suitable for premises with a low or variable occupancy level and a uniform loading.
Equipping the regulator with an occupancy sensor STRZ-09 provides a function in which the regulator regulates the temperature when someone is present in the room. When the room is unmanned, the regulator switches to an economy mode and produces a saving in energy.

CO2 regulation
Suitable for premises with large variations between high and low loading by persons who are present.
Supplementing the system with an STRZ-18 CO2 produces a function in which the regulator increases the ventilation fl ow if the CO2 level exceeds a pre-set maximum threshold value. A good air quality is assured in this way regardless of the loading, at the same time as unnecessary ventilation can be avoided.
