MT500
*These graphs are based on the following conditions :
Inlet water temperature : 15°C
Outlet water temperature : 40°C
Outdoor air temperature : 7°C
Hot water Supply is unlimited in case 8
ℓ
/min at the condition as
the capacity is bigger than hot water supply.
Prioritizing
When the water temperature in the tank drops, heat pump
operation shifts to hot water production. In case there is
demand for both hot water and heating/cooling for long time,
operation mode is periodically switched between hot water and
heating/cooling. For details, see menu 1.0 Hot water temp and
8.5.0 Period settings.
Comfort setting hot water
The integrated water heater is a coil model and is heated by
circulating water, which is heated by the heat pump.
During “normal” consumption it is enough to run the heat
pump to supply the different tapping points of the house with
hot water. The temperature of the hot water in the water heater
then varies between the set values.
Under section 1.0 [N] Hot water temp. on page 25 there is a
complete description of menu settings for hot water
temperatures.
