5 for Fan Coils. Technical Catalogue. With modbus communication, standard motor and ECM motor, technical data For fan coil units - QZB, ductable units QZSR / QZHR, and cassettes QFDK / QZCC The power electronic board is set to carry out different functions and adjustment modes, in order to meet the installation requirements. The communication protocol is the Modbus RTU-RS 485. These modes are selected by setting the configuration dip switches on the board: 2/4 pipe system. Fan ON/OFF thermostatic control. Valve ON/OFF thermostatic control and continuous ventilation. Valve and simultaneous ventilation ON/OFF thermostatic control. Fan operation control depending on the coil temperature (cut-out probe fitted), which can be activated only in heating mode or heating and cooling mode. Automatic switch of the operating mode by means of water probe QZAZ (optional) applied on the 2 pipe system. Seasonal switch by means of remote contact. ON/OFF of the fan coil by means of the remote contact (window or clock contact). Electric heater control By activating the cut-out probe function, the fan is stopped in winter when the coil temperature is lower than 32 C and started when the temperature reaches 36 C. In summer mode, the fan stops when the temperature inside the coil exceeds 22 C and starts when it drops below 18 C. The following connections are located on the power board: Receiver for infra-red remote control (QZAZ or QZAZ-05-94). QZAZ wall mounted control. RS 485 serial connection to manage several fan coils in Master/Slave configuration (it requires the router QZAZ-50-15) or to create a supervisory network (Modbus). The power electronic board is mounted as standard in the cassette QFDK and is available also for ECM motor. - QZB, QZSR, QZCC - QZHR Standard motor ECM motor Mounted unit Not mounted unit Mounted unit Not mounted unit QZAZ QZAZ QZAZ QZAZ Size 1 to 6, standard motor Size 7, standard motor Mounted unit Not mounted unit Mounted unit Not mounted unit QZAZ QZAZ QZAZ QZAZ Fläkt Woods 9416 GB Specifications are subject of alteration without further notice.

The control is equipped with internal sensor to detect the room temperature, which can be defined as a priority compared to the return air sensor on the fan coil.

Modify the set point (when used as a +/- 3 variation of the set point configured from Modbus communication). Set the fan speed (low, medium, high or auto fan).

6 for Fan Coils. Technical Catalogue. With modbus communication, technical data Wall mounted room controller QZAZ Wall control with display that allows controlling one or more units in Master/Slave mode. The control is equipped with internal sensor to detect the room temperature, which can be defined as a priority compared to the return air sensor on the fan coil. The QZAZ control features the following functions: Switch the appliance ON and OFF. Temperature set. Modify the set point (when used as a +/- 3 variation of the set point configured from Modbus communication). Set the fan speed (low, medium, high or auto fan). Set the operation mode (fan only, cooling, heating; auto for 4 pipe systems with mode selection depending on the air temperature). Time setting. Weekly ON/OFF program. Display and change of the fan coil operation parameters. A group of units with power electronic control board can be connected via a serial link and can consequently be managed at the same time by just one QZAZ wall control. It requires a router QZAZ to manage the communication between master and slave(s). By cons the group of units can t be connected to a BMS though the Modbus communication. Using the special jumper present on the board, one unit must be configured as the master, and all the others as slaves. It is clear that the remote control must be pointed at the receiver on the master unit. To avoid problems, it is recommended to install and connect the receiver only on the master unit. One control for each unit (MAXIMUM LENGTH OF THE CONNECTION CABLE = 20 m) One control for more units (20 units max.) (MAXIMUM TOTAL LENGTH OF THE CONNECTION CABLE = 800 m) Fläkt Woods 9416 GB Specifications are subject of alteration without further notice.

7 for Fan Coils. Technical Catalogue. Infra red remote control QZAZ The infra-red remote control QZAZ allows setting by a remote position the fan coil operation parameters. It integrates the following functions: Switch the appliance ON and OFF. Temperature set. Set the fan speed (low, medium, high or auto fan). Set the operation mode (fan only, cooling, heating; auto for 4 pipe systems with mode selection depending on the air temperature). Time setting. 24 hours ON/OFF program.

8 for Fan Coils. Technical Catalogue. Multifunction control QZAZ Another option available for the serial communication between the units is the possibility to connect up to 60 units in series and manage them with just one wall mounted QZAZ controller. The wall mounted controller can be used to set the operating mode for each individual unit connected, display the operating conditions of each individual unit, and set the ON/OFF time sets for each day of the week (the program can be set for all the units and for a maximum of two groups of units). If more than 60 units need to be connected, two or more controllers must be used. Each wall mounted controller only manages the units it is connected to. The QZAZ control is used to manage a series of fan coils, up to a maximum of 60 units (the maximum length of the RS 485 connection cable must not exceed 800 m), from one single control point. The QZAZ control communicates via a serial line with all the units connected, with the possibility of controlling them all together or individually. In fact, the unique address of each individual fan coil means that all the units can be called at the same time, or the individual unit called, to perform the following functions: display the current operating mode, the fan speed, the set point; display the room temperature measured on the individual unit; turn all the units ON and OFF at the same time or alternatively each unit individually; change the operating mode (fan only, heating, cooling, automatic changeover); change the set point; modify the values and operation parameters of the fan speed. Each function can then be sent to all the units connected, or alternatively to each individual unit. Different set points or operating modes can be set for each individual unit. The QZAZ panel can also be used for the time management of the units over the week. Four ON times and four OFF times can be set on the units for each day of the week. A different Temperature set that will be considered as Operation set for all connected appliances, can be set for each event. If the Temperature set is not entered for the individual event, it must be set during programming for each individual unit or for the entire network. s without receiver or with receiver can be connected within the network: the former can receive instructions only from the QZAZ wall mounted panel; while the latter can receive information from both the wall mounted panel (QZAZ-05-96) and infra-red remote control. Use the infra-red remote control to force ON mode of the individual unit, if ON/OFF daily time programming has been set. The unit will regain the settings from the QZAZ panel during execution of successive start-up program. Fläkt Woods 9416 GB Specifications are subject of alteration without further notice.

9 for Fan Coils. Technical Catalogue. Change over sensor QZAZ The QZAZ sensor can be combined with MB boards to be placed on the water supply pipe upstream 3 way valves (not to be used with 2 way valve). The QZAZ sensor must be used as described below: Change-Over for 2-pipe system for the automatic switch of the operating mode. If water temperature is lower than 20 C, cooling mode is set; on the other hand, if water temperature exceeds 30 C, heating mode is set. It can be used on units with electric heater and hot water supply. The T2 priority probe activates the electric heater or water valve, depending on the water temperature detected. If water temperature exceeds 34 C, the water valve ON-OFF control is activated; on the other hand, if water temperature is lower than 30 C, the electric heater is activated.
