Setting an additional heat source (Other thermal)

Fig. 37 “Other thermal” screen page
After opening the “Other thermal” function, user can activate or deactivate the additional heat source, set an external temperature threshold below which it must be activated instead of the heat pump, as well as the logic applicable for managing the replacement.

Available logics are as follows:

• Logic 1: this logic allows enabling operation of the additional heat source to meet the requests of system side only; the 3-way valve will be blocked on this side and any requests from DHW side will be satisfied using the water tank electric heater;
• Logic 2: this logic allows enabling operation of the additional heat source to meet the requests of both system side and DHW side; keeping the unit management of the deviating valve active;
• Logic 3: this logic disables the heat pump and activates a 230V signal to “Other thermal” terminals, which is used to activate the additional heat source. The latter will work as a standalone unit with respect to the unit. When done, save entered data by clicking the key on top right-hand side, as shown in Fig. 37 “Other thermal” screen page.

Notes:

• After activating this function, it will enable start-up of the additional heat source (through a 230V ̴50Hz signal to the terminals labelled as “Other thermal”) if external temperature drops below the value specified in “T other switch on” parameter, or if the “Emergen. mode” is active;
• When selecting “Logic 1” or “Logic 2”, the additional heat source must be set so as to produce hot water with a set-point equal to the one chosen for the heat pump. Moreover, this setting must be executed manually by the user, because the heat pump only provides an enabling signal and there is no chance to edit the hot water set-point for the additional heat source;
• When selecting “Logic 2”, system must be designed to supply water at the same temperature both on system terminal side and on domestic hot water side (this means that system side terminals must include suitable mixing valves to ensure proper management of hot water at inlet);
• It is necessary to install the additional water probe downstream of 3-way valve, which is automatically recognised by the unit;
• The maximum value for hot set-point is 60 °C;
• When using this function, it will not be possible to activate any additional electric heaters;
• This setting will be saved in the event of a power failure.

Optional E-Heater

Fig. 38 “Optional E-Heater” screen page
After opening the “Optional E-Heater” function, user can activate or deactivate any additional electric heater. Said electric heater may have a single or double stage resistor (in case of double-stage resistor user can decide whether to use both stages by specifying the number of resistors in the first parameter). Set an external temperature threshold below which it must be activated instead of the heat pump.

Two control logics are available for “Optional E-Heater” function:

• Logic 1: the additional electric heater and the electric heater in the water tank can NOT work together;
• Logic 2: it is possible to simultaneously start both the heat pump and the optional electric heater after the compressor has been active for four minutes and the value for TO ption water temp. is equal to or lower than that for “WOT-HEAT-At2”.

WARNING
To ensure utmost energy saving, we recommend use of “Logic 1”.
When done, save entered data by clicking the key on top righthand side, as indicated in Fig. 38 “Optional E-Heater” screen page).
Notes:

• After activating this function, it will enable start-up of the additional electric heaters (through a 230V ̴50Hz signal to the terminals labelled as “KM1” and “KM2”; use only “KM1” terminals when using a single resistor) if external temperature drops below the value specified in “T-Eheater” parameter, or if the “Emergen. mode” is active;

• The additional water probe must be installed downstream of the electric heater;

• When using this function, it will not be possible to activate any heat sources (Other thermal);

• The electric heater must be installed downstream the 3-way valve (system terminal side);
  The requests of domestic hot water side will be satisfied using the water tank electric heater;
