# Code
[9.6.3] [5-04] Offset BSH setpoint: Set point
correction for domestic hot water
temperature: set point correction for the
desired domestic hot water
temperature, to be applied at low
outdoor temperature when space
heating priority is enabled. The
corrected (higher) set point 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

space heating, the tank is heated until
the setpoint has been reached.
