DIMENSIONS Heating water Return water Wiring Refrigerant 7. OPERATING PRINCIPLE The heat pump appliance is used to acquire low-temperature energy from the selected source and its transfer to higher temperature level. The air to water heat pump extracts heat from the ambient air. The core of the heat pump serves as an efﬁcient compressor through which the refrigerant is compressed and then expanded in a hermetically closed circuit.
Page 7: Installation And Positioning
8. INSTALLATION AND POSITIONING The installation must be performed by a professional company authorized by the manufacturer. Do not install the appliance by yourself. The appliance might get damaged and people injured. It is possible to suspend the indoor unit on the wall. It has to be placed in the room in a way that enables the access for service and maintenance (see the illustration under).

9. CONNECTION OF THE REFRIGERANT CIRCUIT The heat pump refrigerant circuit connection must be performed by an authorized installation company or a company certiﬁed or trained in air-conditioning and refrigeration services. Do not connect the refrigerant circuit by yourself. There is a serious danger of injury from refrigerant.
Page 9 10.2. SETTINGS The Settings menu is divided into two rows of icons. The top row icons are used for the control of the UTI-INV module (mode, equitherm regulation, HDW etc.), the bottom row icons are used to set the UTI-IQCP control panel (language, time, network connection etc.).
Page 10 10.2.2 Parameters settings The menu with a number of parameters that can be viewed, and modiﬁed, if necessary. The current value of the parameter is displayed.

Page 12 10.2.6 Language setting The UTI-IQCP control panel offers three language versions. When you select the language, the user interface will switch to that language. By pressing the Back button, the setting will be saved and the screen will return to the Settings menu.
Page 13 10.2.9 Network setting It is possible to set the IP address, subnet mask and gateway of the network so that the devices can be connected to the network. If the installation permits, it is possible to activate the DHCP server. DHCP deactivated: DHCP activated: Note: If you don’t know what value to set, do not make any changes, or connect the panel to the network.
Page 14 10.2.11 Factory settings If the panel is not responding, or you have made a setting that led to a non-standard function, it is possible revert the panel to its factory settings: 1. Press the button on the panel for more than 10 seconds. (Note: the button may not be accessible when the panel is installed in a unit.) 2.

Page 16: Maintenance
11. MAINTENANCE Due to its design the heat pump is very easy to maintain. Basic maintenance is performed by the servicing organization once a year. During this regular maintenance, all important elements of the heat pump are checked. Special attention is paid to the correct volume of refrigerant in the circuit and a proper operation of the refrigerant circuit.

Page 22 Selection of the place and installation of the equipment The indoor unit is designed for suspension on the wall using a mounting desk. It has to be placed in the room in a way that enables the access for service and maintenance (see the illustration under). The outdoor unit is designed to be attached to a stand.
Page 23 When capping, do not use mineral oils for any parts. Failing this can cause shortening of equipment’s lifetime. Prior to soldering (min. 50% Ag hard), you must ﬁll the piping with nitrogen gas to prevent ﬂakes. Gas mustn’t be under pressure. The capping must be done with high-quality refrigerator tools.

Page 28 Connection of the ETS temperature sensors The ATW-MINI controller uses a set of digital ETS sensors to monitor the temperature. Each of the sensors is identiﬁed by an address that is assigned to it in production. If you add or change sensor, the new sensors have to be addressed using the ATW-SW software.
Page 29 The amount of melted gases in water depends on water temperature and the gas pressure. In heating water, we talk about melted air consisting mostly of N2, O2, and CO2. Chemically, nitrogen is harmless, but from the operation point of view, nitrogen reacts unfavourably as it reduces the heating capacity of water, increases the compression work and generates cavitation noise.
Page 30 - after the system cools down to 40°C, empty the wash-out water keeping all regulations concerning wastewater, - clean ﬁlters from mechanical dirt, - start ﬁlling the system with the permanent contents immediately. 3) Pressure expansion tank parameters setting The chosen volume and pressure parameters of the expansion tank are important for long-term failure-free operation of the heating system.
Page 31 Attention, pool water mustn´t enter the plate exchanger! Always use an extra exchanger! Attention, water of more than 60°C from another source mustn´t enter the plate exchanger! Example 1: Heating of the accumulation tank to equitherm or constant temperature. ATW-Mini tank outdoor...
