Page 7: Unit Description
TF7038GB_A_NOT UNIT DESCRIPTION The Connect WP is a water-cooled heat pump that uses R410A refrigerant. This interior unit has a hermetic cooling circuit with an inverter rotary piston compressor, as well as a unit- and source-side plate heat exchanger. It is a single-circuit unit. A water filter, differential pressure controller and safety valve are all installed on the sink- and source-side as standard. -

TF7038GB_A_NOT 2.2.2. POSITION OF THE VIBRATION DAMPERS To prevent structure-borne sound from being transferred to the installation surface, it can be helpful to fit the unit with vibration dampers. The intended fixing points are shown on the schematic. Connect WP 120 Connect WP 130 2.2.3. -
Page 9: Components
TF7038GB_A_NOT COMPONENTS 2.3.1. REFRIGERANT CIRCUIT COMPONENTS COMPRESSOR A hermetic inverter rotary piston compressor that is highly efficient and uses an energy-saving DC electric motor. Mounted on elastic vibration-damping compensators. COMPRESSOR INVERTER MODULE The inverter module infinitely controls the compressor speed using the sensor-controlled power specification on the system controller. -

TF7038GB_A_NOT BRINE CIRCUIT EXPANSION VESSEL For the brine circuit, an expansion vessel (membrane type) is already integrated in the heat pump and pre-filled with nitrogen. The expansion vessel must be adapted to the existing system pressure during commissioning. VENTILATION VALVE Used to manually vent the system. - Page 11 TF7038GB_A_NOT ELECTRONIC CONTROL UVR 1611 The unit control panel allows plant operating parameters to be adjusted quickly and intuitively. The display shows various indications of the operating mode, set parameters and any alarms triggered. All standard settings and any changes are saved in the controller control panel. After a power failure, the unit is able to restart automatically and retains the original settings.

Page 16: Integration In The Building Heating System
RECOMMENDATION AND SYSTEM DIAGRAM WITH AWN STRATIFIED STORAGE To integrate an AWN in the heat supply of a building, Aereco recommends a combination with a stratified storage tank with discharge system and preheating stage for domestic hot water (DHW). This enables both an increase in the return flow of the heating circuit during the heating period and support for hot water preparation throughout the year. -
Page 17: Settings For Use With Stratified Storage
TF7038GB_A_NOT SETTINGS FOR USE WITH STRATIFIED STORAGE If the Connect WP is integrated into the building heating system according to the above recommendation (see concept sketch 4.1), the factory settings do not have to be adjusted. Only the following steps need to be taken: Attach the temperature sensor to the lower part of the buffer tank and connect it to input terminal 6 (see circuit diagram). -
Page 18: Setting The Expansion Vessel
TF7038GB_A_NOT SETTING THE EXPANSION VESSEL The standard value for the preload pressure of the expansion vessel is 1.5 bar, the maximum value is 6 bar. Adjust the vessel according to the maximum difference in height (H) of the consumption point (see figure) according to the following formula: [bar] = + 0.3... -
Page 19: Integration Warnings
TF7038GB_A_NOT INTEGRATION WARNINGS CAUTION Based on expertise, the selection and installation of components outside the unit is the responsibility of the installer, who must work in accordance with good engineering practice and the regulations in force in the country of destination. CAUTION The connecting pipes to the machinery must be adequately dimensioned for the actual water flow required by the system when in operation. -
Page 20: Operating Range And Operating Limits
TF7038GB_A_NOT OPERATING RANGE AND OPERATING LIMITS In its standard configuration, the unit is not suitable for installation in a salty environment. The operating limits refer to a temperature difference at the evaporator and at the condenser of �t = 5°C. Whenever the unit is to be operated outside the operating range, we recommend that you contact our technical service department beforehand. -
Page 21: Requirements For Source And Sink Media
TF7038GB_A_NOT REQUIREMENTS FOR SOURCE AND SINK MEDIA In order to ensure the Connect WP operates faultlessly for many years, we strongly recommend filling the two system circuits (AWN brine circuit and heating water charge circuit) with softened and desalinated water. This serves to protect against corrosion and contamination of the heat exchanger. The following limit values must be adhered to: pH value 7.5-9... -
Page 22: Installation
TF7038GB_A_NOT INSTALLATION ON-SITE INSTALLATION REQUIREMENTS Before the heat pump can be installed, the following prerequisites must be fulfilled by the customer: 1. Electrical connections have been made in accordance with local public utility regulations, including the necessary fuses. 2. The electrical wiring between the on-site components, including the data line, has been fully and continuously produced. -
Page 23: Maintenance And Service
TF7038GB_A_NOT 7. MAINTENANCE AND SERVICE EXTRAORDINARY MAINTENANCE The Connect units are factory filled with R410A gas and fully tested. As per standard conditions, technical service does not need to intervene to check the cooling gas. Over time, small losses may occur at the joints causing the refrigerant to leak, draining the circuit. -
Page 24: Regular Maintenance
TF7038GB_A_NOT REGULAR MAINTENANCE Disconnect the unit from the electrical power supply prior to undertaking any cleaning work. Before starting work, make sure that there is no live voltage. Periodic maintenance is essential to keep the unit fully functional, both from a functional and energy point of view. It is therefore essential to provide annual checks for: Test object Target state... - Page 25 TF7038GB_A_NOT Approved refrigerants It is forbidden to fill the refrigerant circuits with a refrigerant other than the one specified. Using a refrigerant other than R410A can seriously damage the compressor. System logbook We recommend that you keep a system logbook, which can be used to trace the operations carried out on the unit.
