6.5 Position of the flow probe
Each unit upper water manifold is equipped
with two pockets where the temperature probe
has to be inserted. The latter probe continu-
ously checks the flow temperature of the heat-
ing circuit. Either you are installing a single
pack or a battery of them, the flow probe must
always be installed inside the pocket placed
downstream, as it is shown in Figure 19.
Of course, in case of more than one Pack in bat-
tery, the probe must be inserted in the pocket
placed downstream on the unit closer to the
system inlet. The temperature difference read
by the probe causes ignition, switching off and
modulation of all the thermal elements in cas-
cade. Installer shall take care to place the probe
inside the pocket which is closer to the system
inlet, in accordance to the water stream .
