Automatic Summer Bypass
Limitations
Whilst the system fan speed doubles, the airflow out of the system will still be relatively limited.
The DVS Reclaim is primarily a continuous low flow ventilation system and normal operation is set
to one third of an airchange per hour (ie. The air in the room will be changed once every 3 hours). At
double flow rates the air will be changed every 1.5 hours.
The summer bypass function is also limited by the outside air temperature. The DVS Reclaim has no
additional cooling ability and is not an air conditioning system.
Automatic Roofspace Bypass (optional extra)
The purpose of the Roofspace bypass is to enable the solar gain available in your roof space air
to be reclaimed by the incoming fresh air flow. This is achieved by opening the roofspace bypass
to allow the roof space air to mix with the extracted exhaust air from your home. This mixed air is
then passed through the heat exchanger resulting in a higher temperature air stream being passed
through the core and thus transferring this higher temperature to the incoming fresh air.
Note: the fresh outside air continues to be the air that enters the house. The roof space air is just
providing additional heat in the form of solar gain to the exhaust air.
This function will automatically activate once the roofspace temperature exceeds the bypass set
temperature and the house temperature is cooler. System fan speed will automatically increase.
To set the bypass temperature:
• Press the Menu button briefly.
• Use the down arrow to select Bypass Temp and press OK.
• Use the up and down arrows to select the temperature, recommended
temperature 25 degrees or over).
• Press OK to confirm your selection, then press the Menu button repeatedly
until you return to the Main Screen.
The bypass indicator will appear on the main screen once activated.
Note: This is an optional extra and will not appear on the control panel unless
installed.
