ROOM FAN COIL UNITS 42N Main drain pan and insulation
The main drain pan incorporates innovative technological solutions: - Horizontal installation: the units can be installed perfectly horizontal - the drain pan structure takes care of the slope, so that the installer avoids complex and time-consuming computations to correctly install the units. - Left or right-hand condensate connection is standard - the installer can easily choose unit connection on one side or the other, just by ﬁxing the plastic cap on the opposite side. - Insulation: the drain pan design allows much tighter contact between drain pan and insulation, reinforced by metal clips to keep the insulation in place. This improves reliability and prevents water dripping from the unit. - The drain pan for the whole range is made of moulded plastic, i.e. more robust, easier and safer to service.
The number of accessories has been reduced to simplify selection and reduce the inventory level. The accessories offered remain unchanged to satisfy any application needs, but the number of codes has been greatly reduced. Aesthetics - Supporting feet - Supporting feet and cover panel - Return air grille for cabinet unit - Rear closing panel - Cabinet on concealed units, - Discharge air sleeve (concealed units only) - Supporting brackets (20 + 20 pieces left and right) Controllers and user interfaces - A/B/C/D-type thermostat - Kit for 33TA0001/33TB0001 installation on 42NM/Z - Cold draught prevention kit - all two-pipe sizes - Automatic changeover switch - all units - Air sensor with 15 m cable - Water sensor kit with 15 m cable - Infrared remote controller (IR2) - Infrared remote receiver kit (IRR) - ZUI1 interface 1 - Wago - ZUI2 interface 2 - RJ11 - SUI1 (with fan speed selection) - SUI2 (without fan speed selection) The units comply with international standards EN603351 and EN60335-2-40 and are certified according to the applicable Eurovent standards for the non-ducted fan coil programme.
PTC electric heater
Electric heater options have been enhanced with the latest PTC (positive temperature coefficient) technology. Their resistance increases as their temperature increases, so the capacity goes down accordingly. This electric heater feature allows fast heating at start-up, the heating capacity is adjusted automatically, whilst ensuring safe and reliable operation. This option is available in low and high capacity for each Idrofan size.
The installation of feet has been greatly simplified and both sides are painted. Just one clip is needed to fix the feet to the units. For this reason and for better reliability during transport, the feet are sold as options - supplied with the unit from the factory (ordering codes Z or P in the 4th digit). They are included with the unit, but not factorymounted.

If the unit received is not as required, the coil and the control box can be switched on site from left to right or vice versa (except units equipped with valves - since their installation is optimised for each side, the valve package must be replaced by a new valve kit).
