Commissioning 6.6

Commissioning 6.6 Technical parameters Simultaneously press the “Esc” and “Menu” buttons until “Insert Code” appears on the display. Turn the selector to enter the technical code (234) then press the selector to confirm; the display will show TECHNICAL AREA. Turn the selector to choose the desired item. – COMPLETE MENU Press the selector . Turn the selector to choose the desired item. 1 ENERGY MANAGER 1.0 BASIC PARAMETERS 1.0.0 IDU type Press the selector . Turn the selector to choose the desired item. 0 None. 1 Hybrid Mode: hybrid hydraulic unit. 2 Hydraulic module: wall-hung or floor-standing hydraulic unit. 3 Light: hydraulic power pack (if any) present, PCB only. Press the selector to confirm. 1.0.1 ODU type Press the selector . Turn the selector to choose the desired item. 1 Heat Pump: electric heat pump. Press the selector to confirm. 1.0.2 Tank management Press the selector . Turn the selector to choose the desired item. 0 None. 1 Storage with NTC: presence of a DHW cylinder with temperature sensor for the NTC cylinder. 2 Storage with Thermostat: presence of a DHW cylinder with temperature managed through a mechanical thermostat (ON/OFF). Press the selector to confirm. 1.0.6 Thermoregulation Press the selector . Turn the selector to choose the desired item. 0 Not active. 1 Active. Press the selector to confirm. 1.1 INPUT CONFIGURATION 1.1.0 HV input 1 (input configurable to 230 V) Press the selector . Turn the selector to choose the desired item. 1 Absent: input not active. 2 EDF: Input not active (0 V). If the comfort function (Par. 1.9.2 Comfort Function) is set as HC-HP, the heat pump and the heating elements are inhibited for heating of the DHW cylinder; if the comfort function is set as HC-HP-40°C, heating of the cylinder is limited to the minimum between the reduced set-point temperature and 40°C. Input active (230V). The heat pump and the heating elements are enabled for heating of the cylinder according to standard logics. 3 SG1: input 1 for the Smart Grid Ready protocol (refer to the paragraph “Standard SG ready”). 4 External switch off signal: switches the machine OFF. Every heating, cooling and DHW request is interrupted while the anti-freeze protection logics are active. 5 Photovoltaic integration: input not active (0 V), no integration. Input active (230 V), the energy surplus is used to increase the DHW set-point by the quantity defined through parameter 1.20.0 PV offset DHW setpoint temperature. If the DHW cylinder has reached the new set-point, it is possible to use this energy to increase the set-point of the inertial storage tank (if present) through parameter 20.4.4 Buffer electric integration offset or of the heating / cooling function to the comfort set-point. Press the selector to confirm. 48 / EN

Commissioning 1.1.1 HV input 2 (input configurable to 230 V) Press the selector . Turn the selector to choose the desired item. 1 Absent: input not active. 2 DLSG: Input not active (0 V), the heating elements are disabled in every operating cycle. 3 SG2: input 2 for the Smart Grid Ready protocol (refer to the paragraph “Standard SG ready”). 4 External switch off signal: switches the machine OFF. Every heating, cooling and DHW request is interrupted while the anti-freeze protection logics are active. 5 Photovoltaic integration: input not active (0 V), no integration. Input active (230 V), the energy surplus is used to increase the DHW set-point by the quantity defined through parameter 1.20.0 PV offset DHW setpoint temperature. If the DHW cylinder has reached the new set-point, it is possible to use this energy to increase the set-point of the inertial storage tank (if present) through parameter 20.4.4 Buffer electric integration offset or of the heating / cooling function to the comfort set-point. Press the selector to confirm. 1.1.3 AUX input 1 Press the selector . Turn the selector to choose the desired item. 0 None. 1 Humidistat sensor: when the contact is closed, the heat pump is turned off during the cooling cycle. Use Par. 1.1.9 Humidity input zone to set the zone pumps that will stop as a result. 2 Heat / Cool by external control: when the contact is closed, the operating mode is set to cooling; when the contact is opened, the operating mode is set to heating. 3 Room thermostat HC3: the signal is interpreted as a contact for a thermostat in zone 3. When the contact is closed, it is sent as a heat request for zone 3. 4 Safety thermostat: connect an underfloor safety thermostat to the contact. When the contact is closed, water circulation is interrupted. 5 Photovoltaic integration: input not active (contact open), no integration. Input active (contact closed), the energy surplus is used to increase the DHW set-point by the quantity defined through parameter 1.20.0 PV offset DHW setpoint temperature - Delta T Setpoint DHW photovoltaic. If the DHW cylinder has reached the new set-point, it is possible to use this energy to increase the set-point of the inertial storage tank (if present) through parameter 20.4.4 Buffer electric integration offset or of the heating / cooling function to the comfort set-point. Press the selector to confirm. 1.1.4 AUX input 2 Press the selector .
