MAIN FEATURES This controller is designed to control Daikin fan coil units. ECFWEB6 Built-in for FWV and FWL ECFWER6 Remote for FWV, FWL and FWM ECFWDER6 Remote for FWD MAIN FUNCTIONS AND EQUIPMENT Regulation of the air temperature via automatic variation of the fan speed. Regulation of the air temperature via ON/OFF switch of the fan at a fixed speed. Regulation of the air temperature via control of ON/OFF valves (on 2-pipe or 4-pipe systems). [. . . ] 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. This table lists the following items for all possible configurations: activated functions Room thermostat with air temperature control Room thermostat with ON-OFF valve for 2-pipe systems Room thermostat with ON-OFF valve for 4-pipe systems system characteristics Number of pipes (2 or 4) Valve ( = present, -- not present) Electric heater ( = present, -- not present) position of the microswitches corresponding controllers relevant reference to dedicated wiring diagram ( ) other conventions for complete understanding of the table: with a number of units in parallel 1~ 3~ 1 phase 3 phase M MD H2O Manual built-in cooling/heating switching mode Manual remote cooling/heating switching mode Automatic cooling/heating switching mode based on the water temperature Automatic cooling/heating switching mode based on the air temperature Choice of the range of the neutral zone Operational enabling signal based on the water temperature Time function (not available for ECFWER6 + ECFWDER6) Electric heater control AIR Installation and operation manual 7 4PW17551-1 ECFWEB6+ECFWER6+ECFWDER6 Microprocessor controller for fan coils Characteristics List of functions activated C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 C16 C17 C18 Standard two pipe system Two pipe system ­ Remote switching mode Two pipe system ­ One valve Two pipe system ­ One valve ­ Remote switching mode Four pipe system ­ Two valves Four pipe system ­ Two valves ­ Remote switching mode Four pipe system Four pipe system ­ Remote switching mode Two pipe system ­ Electric heater Two pipe system ­ Electric heater ­ Remote switching mode Two pipe system ­ One valve ­ Electric heater(a) Two pipe system ­ One valve ­ Electric heater ­ Remote switching mode(a) Two pipe systems ­ Automatic switching on water side(b) Two pipe systems ­ One valve ­ Automatic switching mode on water side(b) Four pipe systems ­ Automatic switching on air side(b) Four pipe systems ­ Two valves ­ Automatic switching on air side(b)(c) Two pipe systems ­ Electric heater ­ Automatic switching mode on air side(b) Two pipe systems ­ One valve ­ Electric heater ­ Automatic switching mode on air side(a)(b) M MD M MD M MD M MD M MD M MD H2O H2O AIR AIR AIR AIR (a) Electric heater control: during heating operation only the electric heater works (b) In this type of configuration, the input for the centralised cooling/heating switching mode is disabled. (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. Proceed as follows to install the controller. 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). Install the air temperature probe (black) and water temperature probe (white) (see figures 13 unto 20) following the instructions given in the paragraph "Installing the air and water temperature probes" on page 11. [. . . ] Always use shielded cable to lengthen the water probe cable. The specifications of the shielded cable are as follows: - maximum length: 100 m - minimum section: 0. 5 mm2 - the shield must be connected to of the basic unit. Do not connect the shield on the controller side in order to avoid electromagnetic interference. For the electrical connection, refer to the appropriate wiring diagram.
