Terminals. The unit can connect to the floor heating device FHL (25 °C-45 °C), fan coil FCU
(45 °C-60 °C), and radiator (60 °C-80 °C), which have different temperature requirements.

Caution
Terminals on the water system side can connect the fan coil (floor heating device/radiator) for heating or a water tank
for water heating. Water heating requires the temperature sensor of the water tank provided among accessories to detect
water tank temperature. The hydraulic module controls the three-way valve to switch to heating or DHW modes.
