LED indicators The various combinations in which the LED lights up indicate procedures and operating status of the controller. Blue and red LEDs lit indicates that the unit did not receive an enabling signal. The water temperature does not enable the air cooling or heating functions (see "Automatic cooling/heating switching mode based on the water temperature" on page 3) or the temperature of the air is within the neutral zone (see "Automatic cooling/heating switching mode based on the air temperature" on page 4). NOTE 7 Water probe 8 Air probe 9 Power interface integrated in controller Control panel Refer to figure 2 to catch the look of the controller. 1 Operation mode selector, to turn the fan coil on and off, to choose the type of operating mode (automatic or at fixed speed) and to control the electric heating. [. . . ] The time function is not foreseen for the ECFWER6 and ECFWDER6 versions. The neutral zone is a parameter related to the function "automatic cooling/heating switching mode based on the air temperature". The neutral zone is a temperature interval astride the set temperature. When the air is warmer than the top limit of the neutral zone, the cooling mode is selected. When the air is cooler than the lower limit of the neutral zone, the heating mode is selected. The following figure illustrates an example with: Neutral zone = 5°C Set room air temperature = 21°C For temperatures above 23. 5°C the cooling operating mode is selected For temperatures below 18. 5°C the heating operating mode is selected. Neutral zone >23. 5°C = 21 21°C <18. 5°C = ECFWEB6+ECFWER6+ECFWDER6 Microprocessor controller for fan coils Installation and operation manual 4PW17551-1 4 Electric heater control Technical data and operation limits Warehouse temperatures ­40°C~85°C 0°C~40°C ±0. 5°C 1. 1 A 0. 15 A The thermostat controls an electric heater as integration or replacement of a hot water heating system. When the operating mode selector switch is turned to and the electric heater is turned on, the fan runs continuously at medium speed. For safety reasons, the fan is turned off 2 minutes after the electric heater is turned off, whether this occurs when the desired air temperature is reached or when the electric heater is turned off manually using the operating mode selector.

(c) For configurations with automatic cooling/heating switching mode based on the air temperature in cooling mode, the fan stops when the valve shuts off. The enabling signal refers to heating mode only (the water probe is placed on the hot water branch. ) Cooling mode (fan) is always enabled apart from the water temperature (there is only one water temperature probe that is used to avoid the fan from running with cold water inside the heat exchanger). ECFWEB6+ECFWER6+ECFWDER6 Microprocessor controller for fan coils Installation and operation manual 4PW17551-1 8 BEFORE INSTALLATION All field wiring and components must be installed by a licensed electrician and must comply with relevant local and national regulations. Before obtaining access to terminals, all power circuits must be interrupted. 3 Feed the cables of the probes if any, in one of the slots of the support and secure the support and controller together using the two screws supplied. (See figure 10, it illustrates the installation of the support and controller when the controller is to be installed on the right hand side of the unit. If the controller is to be installed on the left hand side of the unit, the support is to be turned by 180° compared to the drawing). Ensure that all terminals required for the electrical connections foreseen in the configuration chosen (valve, electric heater, external contacts, . . . ) can be accessed, even after the support has been installed (see the correct wiring diagram). If this is not the case, remove the protective blank tabs from the base of the support first. ECFWEB6 INSTALLATION INSTRUCTIONS Built-in type controller The controller has been specially designed for FWV and FWL units; if used to control other units, make sure its operation limits are respected. Installation on the support and on the fan coil It is advisable to set the microswitches before installing the controller, see paragraph "Setting the microswitches" on page 10. The controller can be installed on both sides of the unit using a support and a cover plate. 1 Unscrew the four screws hidden behind the hatches at the end of the grid and remove the fan coil cabinet (See figure 6). 2 Remove the blank plastic tabs from one of the two slots of the support to be able to reach the "fast-on's" of the controller (see figure 4). (The supplied cables with fast-on's will need to pass through one of the slots of the support, depending on whether the controller is to be installed on the right hand or left hand side of the unit). 1 2 Support Blank tabs 4 5 6 7 8 Complete all electrical connections according to the wiring diagrams. Once the electrical connections have been completed, it is advisable to execute the autodiagnosis procedure to verify functioning of all outputs before you finish installation of the controller (outputs of the fan at various speeds, of the valves and electric heaters if installed): Refer to the paragraph "Installing the air and water temperature probes" on page 11. Assemble the controller-support unit on the fan coil using the bayonet fittings (see figure 11). [. . . ] External auxiliary contact (closed contact = OFF; open contact = ON) CRHC . . . Centralised remote cooling/heating selector switch WIRING DIAGRAMS Once the configuration of the controller has been chosen amongst those listed in the section "Possible configurations" on page 7, combine the table on page 8 with the table at the very end of this manual to find the wiring diagram indicated for the desired solution. Each unit requires a switch (IL) on the power supply line with a distance of at least 3 mm between the opening contacts, and a suitable safety fuse (F). EPIMSA6 . Part of diagram valid only for the centralised remote Cooling/Heating selector switch (CRHC) The code of the terminals on ECFWEB6 controllers can be found on the rear side of the plastic support.
