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 immediately
downstream the EHS.

Units without an integrated pump allow driving an
external one. The signal (1ph ~ 230V, 2A max) is supplied

On PIN 21 of the terminal strip (see Fig. 14) an alarm
input (dry contact) is available to force of the unit.
When the contact is closed (Between pin 21 and 3) the
whole system is turned OFF (Unit OFF, WP OFF, GMC
alarm n° 2). When the dry contact open the system turns

It is possible to use this feature connected with different
external control systems and/or safety devices. For
example in case of danger an external safety device could
send an output alarm signal to close the contact. So the
outdoor unit turns off and remains in that condition until
the dry contact is reopened.

When OAT < Temperature set in UI code 148 (default
value -20°C), if Par 108 is set to 1, on pin 11 of the terminal
strip a signal is available to activate a backup source for
SHW production.
8.7 - Signal for requesting an External Heat Source
(EHS)
Between PINS 4 and N of the terminal strip (see Fig. 14),
there is an output (1ph ~ 230V, 2A max) that can be
programmed using the remote User Interface (see the
control manual, Installation Menu code 106).
Two different strategies are possible based on Outdoor Air
Temperature:
1) Turn off heat pump and activate backup heat source.
This function is activated when OAT < Temperature
set in UI code 148 (default value -20°C). In this region
heat pump turns off and external backup is activated
following one of below logic (UI CODE 154):
• Output always on (UI CODE 154=0) assumes
backup has its own regulation.
• ON/OFF based on room temperature set point
(UI CODE 154=1)
• ON/OFF based on water temperature set point
(CODE 154=2) in case UI is not installed/
available.
2) Both heat pump and backup heat source activated in
case Heat Pump delivered power is not enough. This
function is activated when OAT < Temperature set in
UI code 150 (but OAT > temperature set in UI 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 UI CODE 152) for 10
minutes (value can be set with UI 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
