DIRECT V3 HIU
Model – HIUV3-40 DIRECT type HIU with Priority Hot Water
(Optional Model – HIUV3-40 DIRECT type HIU with Priority Hot Water for UFH)
- Cools the plate after hot water production for prolonged life for the plate heat exchanger.
- Additional shunt pump inside the station, so pump power from the plant room can be significantly reduced as the plant room pump will not have to deal with the pressure losses within the flats
- Heating flow temperature can be controlled from 30°C to 80°C.
- Direct supply for Under Floor Heating OPTION UFH protection with a safety switch.
- Plus an additional UFH protection with a safety switch
- Safety during a power cut. Inlet valve is fail safe, and will not allow overheating of the DHW plate or to any UFH low temperature circuits when the electronic control is not functioning.
- Mixing valve basically controls flow temperature of water to the heating or hot water.
- Pump bypass that works automatically if the unit is in heating mode and all circuits are closed. Water flow passes through the bypass around the heat exchanger protecting the pump.
- Electronic controller, with manual temperature adjustment.
- Shut off valve for either UFH high temperature protection, or Pre-Payment shut down when out of credit.
No additional shut down valve required.
