Note:
When defrosting:
To maintain a supply temperature during by-pass defrosting the preheater need to compensate for the
missing heating capacity. E.g. if the desired supply air temperature is 22 °C, but the heating capacity is only
10 °K the preheater setpoint need to be set to 12 °C.
Unit running:
Example A: To prevent any ice build-up in the exchanger the preheater setpoint need to be 0 °C
Example B: In very cold climates the preheater setpoint need to equal the outdoor temperature used for
dimensioning the unit’s heating capacity. E.g. If the unit is dimensioned for outdoor temperatures down to
-18 °C but outdoor temperatures in this location may be even lower the preheater setpoint need to be
-18 °C.
