To guarantee a correct cooling mode, when working with unregulated direct-heating circles (without cooling
buff er) following 3 requirements have to be fulfi lled.
1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time.
Minimum volume 80 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 1.01 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 2.4 kW
All 3 requirements must be fulfi lled independently. This is possible via the Navigator Pro. The entire distribution
system has to fulfi ll the 3 mentioned requirements. To ensure a large cooling demand, the cooling limit has to
be set as high as possible.
