Min/max water temperature difference = 5/10 °C (in minimum flow conditions, 7 l/min)
MAX return temperature to heat pump = 55°C
MAX outlet temperature to heat pump for DHW production = 58°C
Water circuit pressure min/max = 1/3 bar
Maximum glycol percentage = 40%
The temperature of the fluid leaving the unit must always be within the manufacturer’s specified operating range, even during start-up
and when first putting into heating mode. To ensure this, the water circuit can be fitted with a bypass valve and/or other solutions, such
as electric heaters with temperature control inside the storage tank.
