Install a motorised valve in the flow line when connecting the Vitotrans
222 heat exchanger set for constant flow temperatures without mixer
assembly to a flow distributor (under pressure) (boiler with heating cir-
cuit pump to distributor). The motorised valve will be closed during non-
heating periods, preventing a forced flow through the Vitotrans 222
during such times.
