Heat pump manual reversing valve

H40 - Heat pump type Heat pump operation can be realised with refrigerant (H40=GAS) or water (H40= H2O) changeover. One digital output "Reverse Valve C1, , "Reverse Valve C4" per each circuit is reserved for controlling the reverse flow valve. ZETA ECHOS /HP: reversible heat pump Beside the basic version components, the unit comprises: - 4-way reversing valve; - fluid collector; - a second In this case, the system must be equipped with a shut-off valve on the water recovery line during the HP mode operation, as shown in the manual. The reversing valve solenoid coil shall be energized in cooling mode only. The control system microprocessor board is specifically designed for water source heat pump operation. of operation (1 hour for low-pressure safety), then lockout requiring manual reset will occur. • LEGIONELLA PROTECTION mode The heat pump has an electric heater installed in the hot water tank that is used only to prevent possible outbreaks of legionella. 27 Heating/cooling circuit drain valve. Reversing cycle valve. 28 Electric heater (legionella protection). Liquid line check valve (x4). The reversing valve is a device that reverses the flow of the refrigerant in the piping system. However, there are instances where the reversing valve is off when running cool mode. Therefore, it is important the check the manufacturer's specifications of the heat pump system that you are using STF 4-way reversing valves. • Wide application range - complete capacity range - available for all common refrigerants (R407C The 4 way valves are used in reversible applications such as heat pumps or reversible air conditioning units and chillers. OUTLINE: Supply new 4-WAY reversing valves for R744 trans-critical heat pump. Our customers are global Japanese manufacturers specialized in highly energy efficient electric heat pump and water heaters for domestic, industrial and commercial use. Reverse-return will not fully balance multiple chillers as the variable speed pumps may not always operate at the same speed. An air discharge valve should be installed at the top of the circulation system, if possible, for easy air discharge. As an alternative an automatic/manual air vent can be The software application to which this manual relates has been designed to manage all Cooling Only, Heat Pump ? compressors ON ? fans OFF ? 4-way valve reversed from the heat pump position. The 4-way valve is switched into the same status as during normal heat pump operation until halfway Connect the external reversing valve (QN10) as illus-trated to terminal block X2:10 (N), X2:12 (operation) and X2:13 (L). With several heat pumps connected as master/slave, connect the The reversing valve is controlled by the master heat pump regardless which heat pump it is connected to. Heat Pump Reversing Valve. The heat pump reversing valve is the only difference between the heat pump and standard air conditioner. Previously we have talked about how a heat pump works. We concluded it works just like an air conditioner, moving heat from one place to another. The installation of water-source heat pumps and all associated components, parts, and accessories which Before unit start-up, read all manuals and become familiar with the unit and its operation. Component Typical Blower Relay Typical Reversing Valve Solenoid 30A Compressor Contactor The installation of water-source heat pumps and all associated components, parts, and accessories which Before unit start-up, read all manuals and become familiar with the unit and its operation. Component Typical Blower Relay Typical Reversing Valve Solenoid 30A Compressor Contactor A heat pump reversing valve is an electro-mechanical 4-way valve that reverses the refrigerant (Freon) flow direction, using an electrical magnet. It works very similar to your washer's water valve or solenoid valve (pictured below). When you connect electricity to a valve (energize it), it Checking additional heater. Checking the function of the reversing valve. SMO 05. Chapter 1 | Important information. according to the heat pump's Installation manual. Check the difference between BT2 and BT3 in menu 3. Commissioning without NIBE air/water heat pump.
