Code
Space heating priority: Defines
whether domestic hot water is made by
booster heater only when outdoor
temperature is below space heating priority
temperature. It is recommended to enable this
function to shorten tank heating operation
time and guaranteed domestic hot water
comfort.
▪ 0: Off
▪ 1: On
[5‑01] Equilibrium temperature and [5‑03]
Space heating priority temperature are related
to backup heater. So, you must set [5‑03] equal
or a few degrees higher than [5‑01].
Priority temperature: Defines the
outdoor temperature which below the
domestic hot water will be heated by booster
heater only.
Range: –15°C~35°C
Offset BSH setpoint: Setpoint correction
for domestic hot water temperature: setpoint
correction for the desired domestic hot water
temperature, to be applied at low outdoor
temperature when space heating priority is
enabled. The corrected (higher) setpoint will
make sure that the total heat capacity of the
water in the tank remains approximately
unchanged, by compensating for the colder
bottom water layer of the tank (because the
heat exchanger coil is not operational) with a
warmer top layer.
Range: 0°C~20°C
