A new automatic control of the heat recovery unit bypass damper has been included, which allows outside air to pass through when it is convenient to reduce cooling demands.
In previous versions, the bypass damper of the heat recovery unit was activated if the outside air temperature was within the limits selected by the user. In this new version, the damper will be activated automatically whenever the following conditions are met:
- The outside temperature is higher than the "Minimum outside temperature".
- The indoor air temperature is higher than the "Maximum indoor temperature".
- The outside temperature is lower than the inside temperature.
As of version 2024.b, the control of the heat recovery bypass damper is included in the calculation of the building's energy demand, which will lead to a reduction of the calculated cooling demands in buildings with air conditioning systems or ventilation systems that include this unit.
