Function test
This menu is intended to test the function of the
various components in the product. When the menu
is activated, all the product’s functions stop. Each
component can then be tested separately or together.
All control functions are shut off. The only protection
against incorrect operation are pressure sensors and
the immersion heater’s superheat protection. When you
exit the menu, EcoZenith returns to normal operation.
If no button is pressed for 10 minutes, the product
automatically returns to normal operation.
The exception is if only the brine pump is started. It can
be operated for long periods of time. It is used together
with the external filling pump during installation.
Test radiator system
If two radiator systems are installed, the values for both
are displayed here.

When you exit the menu, CTC
EcoZenith returns to the start menu.
