MVHR works best in airtight buildings, minimising heat loss through natural ventilation. Any heat that could be lost through extraction is actively pumped back into the system, and added to the fresh air. Comfortable conditions. All year round, MVHR makes sure there's a consistent, comfortable temperature indoors.

Boost triggering of these Titon MVHR models is via a 'volt free' switching circuit i.e. it only requires a connection between the two terminals on the control PCB, via a Switch/Contacts. The PCB uses its own 3V DC switching voltage. N.B. In the event that 230V is applied to the PCB it will normally result in unrepairable damage to the PCB

There are three possible solutions to increase the humidity level: 1) Reduce the ventilation rate, e.g. operate the system on level 1 when the house is occupied and on Away-mode when no-one is in the house. 2) Use humidifiers or indoor plants. 3) Use a ERV core within the MVHR unit, which recovers heat and water vapour.

https://www.heatspaceandlight.com/how-mvhr-system-help-stop-summer-overheating/
In winter, the MVHR is extracting warm, humid air from bathrooms, kitchens and utility rooms and passing the heat to the cold incoming air from outside. This airflow exchange is done at a rate that removes CO2, VOCs and excessive humidity and means the incoming air is pre-heated. In summer however, if it's warm inside and outside we don't
