Sanitary water heat pump
27
When the E-heater button on the control panel has been turned on manually, on the display TS2 (E-heater off
temperature) appears and it can be directly modified instead of TS1 (tank setting temperature).
11.4.7 ON/OFF contact
When ON/OFF contact is closed, and the controller is ON, the unit can work and the running mode is decided by the setting of the
controller.
When ON/OFF contact is closed, but the controller is OFF, the unit can’t work.
When ON/OFF contact is opened, but the controller is ON, the unit can’t work (with the exception of external pump).
If the controller is ON, and the ON/OFF status is changed from opened to closed, the unit will work by the previous settings of the
controller (auto-restart).
If the unit was previously in stand-by, in case the ON/OFF status is changed from opened to closed, the unit remains in stand-by.
A signal/warning in case of remote OFF signal (opened contact) is displayed. In such a way the customer can understand why the
unit is not working.
11.4.8 Contact for photovoltaic plant integration
The ON/OFF contact can be configured so that a photovoltaic plant, in max production periods, can be used to obtain the max
value of hot water by the unit (set the parameter 35 to 1). When the contact is closed (activation by FV plant), the tank setting
temperature TS1 is increased to the max possible value compatibly with working limits that are indicated in Paragraph 17.
11.5 PARAMETER CHECKING AND ADJUSTMENT
Some parameters can be checked and adjusted by the controller. Below is the parameter list.

indicated in Paragraph 17 for high water and air
temperatures, the effective water set is automatically
lowered on respect of TS1 that was set by the user.
