NØRDIS OPTIMUS PRO SPLIT AIR-TO-WATER HEAT PUMPS WITHOUT DHW TANK
Air-to-water heat pumps without integrated hot water tank have three-power indoor units. The heat pump system is compatible with underfloor heating, radiators, fan coil systems and domestic water heaters. Therefore, there is no need to invest in redesigning the entire system.
NØRDIS OPTIMUS PRO SPLIT AIR-TO-WATER HEAT PUMPS WITH DHW TANK
Air-to-water heat pumps can be combined with two sizes of indoor units with built-in DHW tanks. The latest technologies integrated into the devices ensure high performance and the lowest operating costs. The combination of heat pump equipment provides optimal possibilities in the process of heating, cooling, and hot water preparation.
FEATURES FOR EQUIPMENT HIGH RELIABILITY
PREHEATING AND DRYING UP FOR FLOOR
Before floor heating, if a large amount of water remains on the floor, the floor may be warped or even ruptured during floor heating operation. We provide two modes for the heating floor, one is the preheating mode which is used after the initial installation of floor loops and the other one is drying up mode for the first heating during seasonal heating. Both of the modes are in order to protect the floor. During the process, the water temperature would be increased gradually.
POWER LIMITATION FUNCTION
Power limitation function makes the machine suitable for a variety of current supplies. There are 8 configurations for user to choose from according to the maximum allowable access current. Only easy setting on the wired controller is needed, the units can suit more application.
The holiday away function is a mode for improving system reliability and saving energy. The unit operates in heating mode and/or DHW mode with low water temperature to prevent water from freezing in the winter during the holiday
outside. The user can pre-set , the disinfection mode before he returns home to make sure that germ free water is available to be used when he returns.
Due to the high level of optimization of technical solutions, the sound pressure level of NØRDIS Optimus Pro 4 kW units is only 35 dB (A) at a distance of 3 meters.
1. Evaporator air in 7°C, 85% R.H., Condenser water in/out 30/35°C
2. Condenser air in 35°C. Evaporator water in/out 23/18°C
NØRDIS air-to-water heat pumps operate automatically according to consumer habits. The maximum user-friend- liness will be ensured by setting the indoor climate and hot water preparation (with the integrated DHW tank in the unit) using scheduling.
CONVENIENT CONTROLLER OR CONTROL VIA MOBILE APP (WIFI)
NØRDIS Optimus Pro heat pumps are controlled by an advanced multifunction controller or an app on a smart device. The app constantly offers optimal system settings to achieve maximum energy savings.
WEATHER TEMPERATURE CURVE
With the help of Weather temperature curve function, water temperature will automatically change as outside air temperature changes. When outdoor air temperature increases/decreases, the heating load will decrease/increase and water temperature will decrease/increase automatically. When outdoor air temperature decreases/increases, the cooling load will decrease/increase and water temperature will increase/decrease automatically. Totally 32 fixed Weather temperature curve and one custom curve is available, which meets the diversified requirements of temperature.
Heat pump adjusts the operation according to different electrical signals. Power consumption of the system can be automatically adjusted according to the peak and valley power to reduce the power consumption to a great extent.
• Cheap electrical signal: DHW mode will be effective to produce hot water.
• Normal electrical signal: Operates according to users’ need.
• Expensive electrical signal: Set the maximum operating time for heating mode and cooling mode.
DHW PUMP FUNCTION
The DHW pump function is used to return water in the water pipe net to the hot water tank according to set timer. Total 12 timers for one day can be set, which allows users to set the DHW pump operation time according to using habit to guarantee using hot water without waiting for a long time.
NØRDIS Optimus Pro heat pumps are an ecological and environmentally friendly home heating and hot water solution using renewable energy sources. Energy efficiency class A+++.
ECOLOGICAL R32 REFRIGERANT
R-32 is an environmentally friendly refrigerant used in modern equipment. Advantages over the predecessor R410A:
• Low Global Warming Potential (GWP) Refrigerant.
• Higher heat transfer coefficient for better performance.
• The system requires less refrigerant.
