13.2.2 - aTm size 2 available static pressure curve (pa) as a function of air flow (m 3 /h or l/s) Available pressure, Pa Legend: Without electric heater (with 6-row water coil) With electric heater (with 5-row water coil) U Fan motor power supply 28 Air flow, Qv IMPORTANT: The curves were derived by smoothing, based on the information contained in the electrical data table.
14 - controLLer 14.1 - carrier numeric controller At the top of the range, each ATM is fitted with a programmable numeric controller. The main functions of the controller are: • Controlling room temperature • Raising, lowering and adjusting the angle of Venetian blinds (optional) • Brightening and dimming light sources (optional) • Selecting comfort or unoccupied mode through a Zone User Interface or wall thermostat • Controlling ventilation (e.g. by selecting forced ventilation mode). NOTE: For further information, please refer to the selection manual, installation manual or start-up handbook for the Carrier numeric controller. 14.2 - carrier electromechanical controller with fan speed controller 14.2.1 - speed controller Inputting a preselected speed This input gives three speed settings to the speed controller. The speeds are each adjustable by a potentiometer on the face of the controller. Setting the speed is achieved when the supply power is applied to one of the 3 input pre-selections. Speed control potentiometer ranges are: • low speed 80 to 120 V (± 15 V) • medium speed 110 to 170 V (± 15 V) • high speed 160 to 225 V (± 15 V) The output ranges are given for a supply network input voltage of 230 V.a.c. (RMS). Control input 0-10 v.d.c. This signal has two operating bands: • between 0 and 2 V (± 150 mV), the output is zero • between 2 V (± 150 mV) and 10 V, the output ranges from 80 V (± 15 V) to 225 V (± 15 V), for an input voltage of 230 V.a.c. WARNING: Only one of the 2 different control inputs should be selected, otherwise the fan speed controller will be damaged. Control voltage V Supply network (supply to fan motor) 14.2.2 - general characteristics Selection of inputting a 230 V.a.c. or 0 to 10 V control input is automatic. An LED on the face of the controller shows when it is on. NOTE: Note that the controller has a circuit which forces the selection of high speed for 2 seconds when: • power is switched on • an input control signal from 0 to 10 V at a level higher than 2 V is established • a speed is selected • Power supply: 230 V ± 15% • Output voltage range: 80 to 225 V (± 15 V) • Screw terminal connections: size 2 x 1.5 mm 2 • Full load starting capability • Overload capacity: + 50% of maximum power for one minute • DIN enclosure, 12 screw terminals • IP 201 protection • Operating environment: + 5°C to + 40°C, 85% to 40% RH • Power input 2.5 VA • CE compliance: - in accordance with EMC directive 89/336/EEC, - in accordance with low-voltage directive 73/23/ EEC dated 19/02/73 as amended by directive 93/68/EEC dated 22/07/93. The speed control option also has a terminal block for connecting control valve cables or electric heater cables as appropriate. The controller and terminal block are protected by a selfextinguishing ABS plastic cover. The Carrier speed controller is the indispensable interface between the ATM and proprietary controllers of the fan coil type. V 29
