NOTES:
1. When this function is activated, it permits the activation of the replacement heat source (via a 230V ~
50Hz signal to the "Other thermal" terminals) if the outside temperature falls below the value speci-
fied in the “Additional heat source temp.“ parameter or if “Emergency mode” is activated.
2. If you select “Logic 1” or “Logic 2“, the additional heat source must be set so as to produce hot water
with a set-point equal to that selected for the heat pump. This setting must be made manually by the
user, as the heat pump gives consent only (without the possibility to alter the hot water production
set-point on the additional heat source).
3. If you select “Logic 2”, the system must be designed to supply the system terminal side and the DHW
side with water at the same temperature (so the system-side terminals must necessarily be fitted
with mixer valves to ensure the hot inlet water is correctly managed).
4. The supplementary water probe must be installed downstream of the 3-way valve (for more infor-
mation, refer to the installation manual).
5. The maximum value for the heating set-point is 60°C, whereas the set-point in DHW mode must be
between “DHW tank T“ (paragraph 5.2) + 5°C and 60°C.
6. If this function is used, no additional electric heaters can be enabled (optional elec. heater).
7. If the relative function is activated (paragraph 8.3), the value of these parameters will be stored in the
memory and automatically reset after any possible voltage failure.
8. In the case of BHP, only Logic 1 and Logic 3 can be used. The additional water probe supplied must
be replaced and positioned as shown in the Installation Manual.
