Regulation

The unit is equipped with a fully automatic control system with flow regulation according to relative humidity without the need for any further intervention in the control of the unit. The unit is equipped with four combined temperature and relative humidity sensors. The performance characteristics for each speed are indicated in the performance characteristics. The designer wired controller allows for fan speed adjustment, manual by-pass control, BOOST function activation, automatic operation activation and filter clogging indication. Other unit settings are made using the DIP switches and potentiometers on the unit's control board when the front cover is removed. A weekly program can be set for the automatic mode. The frost protection system allows the unit to operate down to an outdoor temperature of -10 °C without the need for additional preheating or reheating. The NEMBUS 210 can be supplemented with NEMBUS-VOC and SABIK-NEMBUS-SF constant airflow modules. Connection to Connectair (cloud S&P) is possible.

Mounting

The unit is designed for horizontal ceiling mounting or vertical wall mounting indoors. The required ambient temperature is between 10 and 50 °C. The unit shall be mounted to provide sufficient space for removal of the unit face, replacement of filters, connection of the condensate drain to the SF-P 138 odour trap and for periodic inspection of the wiring. If the unit is mounted above the soffit, an inspection opening for the operator is required.

Accessories

- ED Flex^® System circular ductwork
- AIRSENS-CO2 spatial CO₂
- NEMBUS-PH integrated preheat
- NEMBUS-VOC integrated VOC sensor
- SONOULTRA flexible silencer
- SABIK-NEMBUS-SF module for constant air flow

Instructions

The unit is not equipped with its own heater as standard. If preheating is required, an integrable NEMBUS-PH module or external MBE and MBW duct heaters with corresponding control elements can be used. After basic set-up by the installer, the unit requires no further adjustment. Filter changes are recommended at least once a year. The design of the ventilation system and its use in buildings with category B gas appliances (gas boilers and open chamber water heaters) or open hearth appliances burning solid or liquid fuels with flue gas exhaust to the chimney is governed by the applicable regulations. Ventilation must comply with the building fire safety regulations.
