Antifreeze electric coil (external)
The antifreeze system consists of an electric coil installed on the fresh air inlet. It is supplied in a dedicated section external
to the base unit to be fixed using an installation kit supplied with it.
Defrost system (internal)
The automatic defrost system consists of a self-regulating electric coil in PWM mode of the input power, installed on the
return air intake. The system is controlled by a special temperature probe positioned on the exhaust air and guarantees a
considerable reduction of the input power compared to the traditional systems available on the market.
Electric re-heating coil (internal)
All units may be equipped with an internal re-heating electric coil, made up of armoured steel electric heaters, supplied
complete with PWM control system, safety thermostat already wired and installed on board.
Air damper with actuator
This is installed on board the unit and operate to exclude the fresh air intake and/or the room return air flow. This option is
particularly useful in areas with very cold winter temperatures, where it is necessary to avoid dangerous self-induced cold
air flows by the installation itself, during the stand-by period of the unit, with the risk of freezing the water contained in the
water coils, if any. The damper is controlled by On/Off actuator for the opening or the closing, or with return closing spring.
Sound attenuator on return / supply side (external)
The sound attenuator is supplied in a dedicated section external to the base unit, with the same sizes and features of the main
unit, to be fixed using an installation kit supplied with it.
The sound attenuator baffles are made of mineral wool, thickness 100/200 mm, density 90 kg/m 3 , protected by a fabric veil
that prevents any risk of fraying of the mineral wool even at high air velocities.
The mineral wool is contained in a galvanised frame with a galvanised steel microstretched retaining mesh.
The sound-absorbing material is class M0.
CO probe
2
CONTROL BASIC version units can be equipped with air quality CO probe. This accessory is installed and wired in the factory.
2
If it's installed on the return air duct it allows to determine the quantity of carbon dioxide present in the environment,
increasing the quantity of external air to dilute its content.
ATTENTION: The CO
probe is not available in CONTROL EVO COP and CONTROL EVO CAV versions.
