4.8.6 Balance tank temperature control
The balance tank temperature sensor is used to control switch-on/o of the heat pump.
When the heat pump stops, the internal pump stops to save energy and the balance tank provides hot water to heat
the room. Furthermore, temperature control of the balance tank allows both room heating and domestic hot water
requirements to be fulfilled simultaneously. The balance tank can store energy to provide hot water while the heat
pump runs in heating/cooling mode, which can reduce host selection and initial investment.
4.8.7 USB data transfer
• Convenient programme update
• Transmission of parameter settings between wired controllers. It is recommended to do this in case there is
a master back-up so as to copy all configurable parameters exactly. Otherwise, only a few key parameters
remain in the M/S system memory when the Master fails.
