The HVR incorporates a fully automatic control system based on a seasonal control strategy. The seasonal strategy is determined by time and date but is weather compensated to pick up unseasonal conditions. The system provides natural ventilation as the default method of ventilation indicating when manual windows or automatically opening dampers should be utilised to maximise IAQ and maintain comfort levels.
The control system incorporates a number of temperature sensors integral to the unit to monitor external temperature, mixed air temperature and supply air temperature. In addition, a wall mounted controller fitted with an internal temperature, CO2 sensor and user override are included as standard. Data is stored per minute on an integral data card for data analysis and compliance requirements.
