SYSTEM MANAGEMENT

The NADISYSTEM control system for residential applications

gives high operating flexibility by controlling the secondary cir-

cuits, that is, activating zone pumps and valves depending on

the room temperature set on the remote keypad, and by con-

trolling mixing valves to ensure the correct water temperature in

radiant systems according to the climate conditions set for each

circuit.

There are 15 different types of pre-configured system for quick

and easy installation, with the possibility to manage up to 5

remote keypads for controlling thermal load in likewise zones.

If the radiant system also needs to meet cooling demand,

humidity control is guaranteed by activating the dehumidifier

contact, while calculation of the dew point, measured by the N-

THC controller, ensures the correct water outlet temperature

defined by the cooling compensation curve, thus avoiding for-

mation of condensate on the floor.

Remember to suitably insulate the pipes in contact with the air,

if air-conditioning in used inn summer.

The following table indicates the different type of systems that

can be controlled directly by the NadiSystem.
