Sentinel Totus 2 D-ERV Installation, Operation and Maintenance
Product Description
Sentinel Totus 2 D-ERV
Sentinel Totus 2 Demand Energy Recovery Ventilation (D-ERV) is a heat recovery demand ventilation
system designed to meet modern building management and control principles.
Employing a range of sensors to manage the system, demand is typically sensed by PIR, temperature,
humidity, air quality, carbon dioxide sensors or other types of Vent-Axia proprietary sensors (see Appendix B:
Options and Accessories on page 63 for details).
It can respond to the ventilation requirements of a room by providing airflow only when it is required and at the
level that is required, using only the energy that is needed, while recovering maximum energy from the
extracted air and transferring it to the fresh supply air. This overcomes many of the drawbacks encountered with
traditional fixed volume ventilation systems, which operate irrespective of the occupancy of the room, leading to
over ventilation and a wasteful use of energy.
Note that the unit contains heaters, which automatically prevent the heat recovery cell from freezing and can
also be used to “Top Up” the air temperature to the room.
