For drying buildings, the heat pump can
be used in addition to the instantaneous
heating water heater (accessory).
If the heat pump is not ready for use (e.g.
primary circuit is not yet completed), this
function must be set to
"No" (delivered
condition).
Note
■ When using the heat pump to dry a
building, observe the loading of the
geothermal probe.
■ Drying buildings with an instantaneous
heating water heater (accessory)
results in high power consumption.
"Yes" Heat pump is used for drying
a building.
"No" Heat pump is not used for dry-
ing a building.

Please note
Risk of damage to building
through overheating screed with
high flow temperatures.
Install a temperature limiter into
the flow of the underfloor heating
circuit to limit the maximum tem-
perature.
■ The screed programme affects all ena-
bled heating circuits in parallel.
■ The selected "Screed program" con-
tinues after a power failure or after the
heat pump control unit has been
switched off.
■ The selected operating programme
continues if the "Screed program"
has terminated in accordance with the
programme or, before its expiry, the
temperature/time profile "
0 " is selec-
ted.
■ The temperature/time profiles 7 to 12
regulate to the maximum flow temper-
ature.
■ If the time profile shows a higher set
flow temperature, the set temperature
is limited by parameter
"Max. flow
temp" (page 198) of the heating cir-
cuit.
■ The power consumption increases
when using an instantaneous heating
water heater (accessory) for drying
buildings.
