Blocking heating valve during summer season
During the summer, it is possible to block the heating valve at high outside air temperatures to save energy on heating load. With parameter OAT-01 the temperature can be defined, above which the heating valve will stay closed.
Note: The HeatCtrlSig output signal will be automatically released again; if the coded signal HumidityMode equals the value of “2” (dehumidification is needed).
Blocking cooling valve during winter season
During the winter, it is possible to block the cooling valve at low outside air temperatures to save energy on cooling load. With parameter OAT-02 the temperature can be defined, below which the cooling valve will stay closed.
