Summer Bypass Mode - Vent-Axia 405215 Installation And User Manual

Summer Bypass Mode

The Sentinel Kinetic Advance includes a Summer Bypass (SBP) feature to bypass the heat exchanger to
provide cooling when the desired Indoor Temperature is above the ambient temperature.
Note that the volume of air provided by a ventilation system is a fraction of that required for space heating or
space cooling and will not in itself be sufficient to cool a room. It will however, provide a contribution.
Modes of operation
Bypass Mode
Off
Normal
Evening Fresh
Night Time Fresh
Bypass mode will operate when both the Indoor and Outdoor temperature thresholds are exceeded, and the
outdoor temperature is below the indoor temperature.
Indoor Temp: This is the maximum desired indoor temperature. Above the set indoor temperature the
summer bypass will operate.
Indoor temp should be set, 2-3°C higher than the central heating thermostat to prevent the bypass operating
in winter, and 2-3°C lower than any air conditioning thermostat if fitted.
Outdoor Temp: This is the minimum allowed outdoor air temperature. The air temperature must be above
this value for the Bypass to operate, use this value to prevent the bypass operating in winter.
The suggested Outdoor Temp, is 14°C, set as appropriate for your region.
Bypass mode will be cancelled when either:
- The internal air temperature drops below the Indoor Temp threshold, or
- The external air temperature drops below the Outdoor Temp threshold
Note: Pressing the Boost button during Evening Fresh and Night Time fresh operation will revert the unit to
Normal bypass mode.
It is recommended that the user selected mode chosen for Evening Fresh and Night Time Fresh is higher
than Normal flow rate to reduce the indoor temperature more rapidly.
*Night Time Fresh Mode is intended for use through the night when cooling is a higher priority than any
increase of noise. Note, that the air noise in your system is influenced by flowrate, ducting design, layout
and the size and type of vents used in the rooms. If improvements are required please contact your
installer.
