Ensuring circulation and temperature control of the heat carrier in heat exchangers of ventilation systems and supply air installations.

Functions are performed by regulating the temperature of the supplied heat carrier at its constant flow rate.

UWS 1-E units are always supplied in the right-hand version (when viewed from the side of the two-way valve drive and the circulation pump motor, the heat carrier flow in the internal UWS 1-E circuit moves counterclockwise).

UWS 2-E units are always supplied in the left-hand version (when viewed from the side of the three-way valve drive and the circulation pump motor, the heat carrier flow in the internal circuit of UWS 2-E moves clockwise).
