How to calculate the buffer tank capacity?[ 11-21 15:49 ]
The minimum water volume is 12L/KW.If you install 15KW heat pump, the mini. buffer tank capacity is equal to 12*15=180L.There is no limit for the maximum, to some extent, the larger, the better.
Why the parameter could not make change?[ 11-21 15:49 ]
HISEER heat pumps adopt with Siemens controller.When the heat pump is running, it is dangerous to change some of the key running data or change something by mistake.
What is the advantage of changeable temperature control ?[ 11-21 15:49 ]
HISEER heat pumps adopt with Siemens or Carel controller.There are fixed temperature control and changeable temperature control.When SF04=1, the heat pump will be controlled by outdoor temperature, indoor temperature and the heating compensation coefficient curve factor. Any of the 3 factors changes, the control temperature will verify accordingly.
Why a buffer tank is required ?[ 11-21 15:48 ]
A buffer tank is recommended to ensure a trouble free heat pump operation.When a buffer tank is installed, the heating or cooling system will absorb energy from the buffer tank first to save energy consumption.
Why water flow alarm usually blinks for newly installed heat pump?[ 11-21 15:47 ]
For newly installed heat pump, if there is air in the heat pump system, water flow alarm will usually blink, the heat pump could not be started.Totally vacuum the heat pump and the water flow volume reach the standard requirement, the water flow alarm will disappear.
Why there is no hot water for my heat pump?[ 11-21 15:44 ]
