3.9. Cooling data detailed iPump A 2-7
To guarantee a correct cooling mode, when working with unregulated direct-heating circles (without cooling
bu
ff
er) following 3 requirements have to be ful
fi
lled.
1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time.
Minimum volume 54 lt.
2. To ensure the minimum
fl
ow rate of heating site, appropriate zones have to remain open all the time.
Minimum
fl
ow rate 0.72 m³/h
3. To ensure the minimum cooling output rate of distribution system, appropriate zones have to remain open
all the time. The minimum cooling output rate is 70 % of the minimum cooling output power of the heat-
pump at A35°C/W18°C.
Minimum cooling consumption 1.75 kW
All 3 requirements must be ful
fi
lled independently. This is possible via the Navigator Pro. The entire distribution
system has to ful
fi
ll the 3 mentioned requirements. To ensure a large cooling demand, the cooling limit has to
be set as high as possible.
