Note
■ Output data to EN 14511 correspond
to a temperature spread of 3 K at a
brine inlet temperature of 0 °C and
brine outlet of –3 °C.
■ The specified flow rates are rounded
up or down.
■ Operation as water/water heat pump
with intermediate circuit:
If the brine temperature of the inter-
mediate circuit is reduced to 8 °C from
10 °C, the heat pump output is
reduced by approx. 5 %
