The water coils shall be provided with manual air purge valves. • The cooling and heating coils shall be made from copper tubes of 3/8” external diameter and aluminium fins. The maximum water side working pressure shall not exceed 10 bar (1000 kPa). • The aluminium drain pan beneath the coil and valves shall be monobloc to avoid the possibility of leaks. • The two-way or three-way on/off water flow control valves shall be provided with flexible water pipes with 1/2” BSP union nuts to simplify connections on site and maintenance and servicing work. • 42EM units supplied shall be provided with disposable 85% gravimetric (G3) and M1 fire class filters. • Filter access shall be: - From below the unit for ducted models, - From the rear of the unit for non-ducted models. • The 42EM shall be equipped with a LEC (Low Energy Consumption) type fan motor assembly. • This direct-drive motor shall be electronically commutated (EC motor), controlled by a 0-10 V signal, allowing it to operate precisely, simply and quietly with a wide range of rotational speeds in variation from the original speed. • Fans shall be a double-inlet centrifugal forward-curved type, with 1 or 2 fans per unit depending upon unit size. • 42EM units shall be suitable for connection to electronic controllers (wall-mounted thermostats) that allow fan speed changes to adjust the unit’s heating and cooling capacity. • Electrical connections carried out on 42EM units shall be the quick-connection type in order to simplify maintenance. A plastic cover shall protect the terminals. Numerical control • The numerical controls shall use the CCN (Carrier Comfort Network) communication protocol. • These controls shall have the following functions: - Control of the Atmosphera fan speed. - Control of the water flow through the on/off type two or three-way valves with reference to internal and external loads, in order to maintain a constant ambient temperature in the conditioned space. - Provide on/off control of the resistance wire type electric heater. - Be controlled by a Zone User Interface. • The power supply to the controller shall be 230 V a.c. (± 10%) single-phase, 50 Hz, to avoid the need for a transformer. The electric heater shall be controlled directly from the numerical controller to avoid the need for a power Triac. 29 Order No.: 14225-20, 01.2015. Supersedes order No.: 14225-20, 09.2014.
