Fan coil wiring diagram.
Circulation for temperature detection.
When activated, it allows low-speed air to circulate at regular
intervals for more precise control of room temperature.
Temperature oset for valve closure.
Allows you to select at which temperature below/above the
set point to close the 2-way valve
Cold anti-fan function.
Prevents the unit from remaining on in heating mode when
the inlet water temperature is too cold
