Ventilation Control dT200

Description

The dT200 ventilation control unit has two digital measurement sensors for recording indoor and outdoor temperatures and relative humidity. These data are used to calculate the so-called dew point temperatures using a calculation algorithm. The dew point temperature is the temperature below which water vapour condenses on surfaces. Condensation on building wall surfaces offers ideal conditions for the formation of mould and the occurrence of water damage. The unit reliably prevents condensation in interiors. When combined with a dew point monitoring mode, or even if used separately, the temperature of the interior area can be controlled. The unit can be set to heating, cooling & heating and cooling with a defined target value.
