This manual introduces the features and operation methods of SHR series and VHR series heat recovery ventilators.
This manual provides operating instructions for Fantech SHR and VHR series Heat Recovery Ventilators (HRVs). It explains the function of HRVs in whole-house ventilation systems, detailing how they use a sensible heat recovery core to transfer heat between air streams for energy efficiency. The document covers port configurations and seasonal operation strategies to manage humidity and prevent condensation.
An HRV is designed to bring fresh air into a building while exhausting an equal amount of stale air.
When the supply air stream temperature goes below -5°C (23°F), the exhaust fan shuts down, the supply fan goes to "High" speed, and a damper closes the supply, opening a 5th collar.
Low speed continuous ventilation with high speed override is recommended.
When the supply air stream temperature goes below -5°C (23°F), the supply fan shuts down and the exhaust fan goes into "High" speed.
