there is an output (1ph ~ 230V, 2A max) that can be
programmed using the remote User Comfort Interface (see
the control manual, Installation Menu code 106).
when OAT < Temperature set in nui code 150 (but OAT >
temperature set in KHP0008 code 148). In this region HP
keeps working and backup heater turns on if set point on
water is not reached by 5°C (value can be set with KHP0008
CODE 152) for 10 minutes (value can be set with NUI CODE
151). Backup heater turns off when set point on water is
reached again.
IMPORTANT NOTICE :
In case of SHW activation (pins 13-15 closed) heat pump
will turn on and backup heater will turn off. This will happen
in both the above strategies.
WARNING :
In case of EHS installation, it is mandatory to install a
thermal switch on the water circuit to protect the system
from too high water temperatures. This protection item has
to be located downstream from the EHS.
Additional water circulator for Aeromax Plus
It is possible to connect an additional water pump through
the
pins 12 and N. It is managed in the following way:

Note: The maximum total instantaneous current must be less than 3.5A. In the case of loads with higher
absorbed current, it is necessary to drive the loads with relays to be inserted between the power supply of the
load itself and drive the relays from the terminal strip.
