Controller operation
Miscellaneous
-
During summer or mid season, do not switch OFF the
main switch and the CDU breaker. Stop the CDU and
any heating/cooling operation, by setting code 0 to OFF.
Switching OFF the main switch or the CDU breaker, might
damage the CDU.
-
With code 33, it is possible to reduce the maximum
frequency of the compressor; if the maximum frequency
is reduced, the CDU will be less noisy but also less
powerful, therefore the auxiliary heaters, if available, will
be switched on more often.
-
When code 0 is set to OFF, the water pumps are switched
on for 10 minutes every day, to avoid the risk of pump
locking.
-
Inversion of heating to cooling operation or vice versa is
delayed for 3 minutes.

See paragraph Refrigerant connections for distances and
height diff erences between hydronic module and CDU.
-
In case of installation with fan coils, a minimum water
quantity of 4 liters / kW is required; install a buff er tank if
required.

The hydronic module has been fully tested by the
manufacturer; this could cause water residuals inside
the system. During installation phase, eventual water
residuals could come out from hydronic module water
