De Dietrich EA 108 Notice Installation page 18

The EA 108 hydraulic unit slows down heating return from boilers
using solid fuels thanks to the thermostatic mixing valve. In the start-
up phase, the thermostatic valve remains closed. The installation is
short circuited, which allows the installation rapidly to reach the
operating temperature whilst preventing the formation of
condensates. In the absence of condensates, the boilers' lifespan is
prolonged.
