WATER CONTROL
The checking of water temperature to enable valve opening
is a function that concerns only configurations with 3-way
valves and heating element. In such configurations the water
temperature will be checked in the following cases:
 H eating with heat element: operation of the heating element
will force the fan to switch on; it is therefore necessary to
prevent excessively cold water from passing through the
unit.
 P ost-ventilation due to switching off of the heating element:
this function will be maintained until the set time has
elapsed, even if the operating mode is changed. During
post-ventilation the water temperature enabling signal will
coincide with the one seen for fan operation.
DISPLAY
