The water tank should not be installed more than 3 meters lower than the foundation of the heat pump; It is suggested to install the heat pump, the water tank and the circulation pump at the same level. Besides, the height difference between the heat pump and water is not suggested to be more than 3M when the water tank position is higher than that of the heat pump, in order to save power of circulation pump as much as possible.

6. The reasonable allocation of the heat pump and water tanks volume should deploy by 1/0.6 as maximum. Please refer to the following recommended buffer tank models and daily hot water tank models. Buffer tank volume should be bigger for indoor radiator system, While can be smaller for floor heating system. Daily hot water tank volume should be according to family persons and the way of bath or shower.

5.2.3 3-way-valve installation SUNDEZ SDRS series heat pumps have heating mode and hot water mode. The hot water mode is priority over heating mode. There are 3 modes for selection: heating only, hot water only, heating+hot water. The 3-way-valve is installed in the water circuit to switch between heating and hot water. 1). The 3-way-valve is energized when the controller is at hot water mode. 2). The 3-way-valve is not energized when the controller is at heating mode. There is the control output terminal in the electric system. The wires of the 3-way-valve should be connected to this output terminal.
5.2.4 Heating sensor and DHW sensor installation Both the heating mode and DHW mode have their own temperature sensors respectively. The heating sensor should be put into the buffer tank, and the DHW sensor should be placed into the DHW tank. Both of the two sensors are from the electric system in the heat pump. In some cases, The cables of the two sensors need to be prolonged. Silicon would be necessary to make sure good heat transfer, so that the sensor can feel the temperature accurately, when installed into the temperature probe in the water tanks.

7.6.6 Heat curves Temperature compensation (heat curves) is called weather compensation or climate compensation, which can automatically adjust the heating water temperature set value as the outdoor temperature changes. Heat loss of the house would change when the outdoor temperature changes. So, this function can make indoor air temperature more stable and more comfortable. This function is a standard function built-in the heating mode, and the ambient temp. datum point can be adjusted according to local climate. The following diagram shows how the heat curve works. The T3 is actually the parameter F7 (Ambient T. datum) in the controller. The range is -10DegC~20DegC, and the default value is 0DegC.
