In order to guarantee a correct cooling mode, when working with unregulated direct-heating circles (without
cooling buffer), the 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 S30°C/W18°C. Minimum cooling power consumption 2.8 kW
All 3 requirements must be fulfi lled independently. This is possible applying 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.
