When installed alone, YuNa II is compatible with low to
medium temperature emitters (underfloor heating, fan coil
units, water cassettes, radiators, mixed installations, etc.).
YuNa II is also compatible with high temperature emitters for
boiler backup operation.
each device is tested in the factory and delivered ready for
operation.
If the heat pump is the only source of heat:
Below this temperature, heating must be provided by a
separate heating source or an additional electrical supply.
If the heat pump is used for backup operation:
Operates down to the equilibrium point (temperature below
which the heat pump can no longer keep up with heating
needs). Below this point, the heat pump and boiler run
alternately (heat pump OR boiler).
