[. . . ] This contact can also be linked to an external timer system. C) Sensor set to enable both functions: In 2-pipe systems the sensor detects the supply water temperature and determines the summer or winter function mode. The fan function consent during the winter operating mode is given with a configurable delay time set in Parameter 24. Analogue and digital outputs FAN: Fan speed control, from one to three speeds. A 230 Vac output, 50 Hz . Max 1. 25 (3 peak)A. WINDOW: The closed contact indicates that the window is open. [. . . ] 2 : 2-PIPE FAN COIL WITH AN ON-OFF & PWM ACTUATOR The set point is set to the upper point (to the lower point for cooling) of the proportional band, so the valve is closed when the temperature exceeds the set point. The valve opening percentage is regulated by the P+I algorithm. 2nd speed when (set point -90% of the BP) <Tamb < (set point ­30% of the BP). The minimum time at this speed is 2 minutes in normal conditions. 3rd speed when Tamb < (set point ­90%). The minimum time at this speed is 2 minutes in normal conditions. If a variation of more than the BP value occurs between the set point and the actual temperature, the minimum length of time in any one state is reduced to 5 seconds. If the action is cooling, fan control will be opposite to that used during the heating action. During the cooling cycle function, and if the set point is satisfied, the fan will continue to operate at speed 1 for 3 minutes, and will then stop. 4 EN0H8560UK07 R0 RFC BASIC FAN COIL CONTROLLER 4-PIPE FAN COIL WITH ON-OFF & PWM OUTPUT: Fig. 3 4-PIPE FAN COIL WITH ON-OFF & PWM Valve Opens XpH ZEB XpC ORANGE LED BLINKING (1 second ON and 15 seconds OFF) in the OFF state. MODE LED: Function mode display The flashing of the Mode LED shows the current state of the regulator (COMFORT or ECONOMY). When pressing the SEL 3 key, the changes to the flashing of the Mode LED indicates the state of the device. In particular: 0% Temperature C Set o With the controller in COMFORT mode: when pressing the SEL 3 key the Mode LED turns on. With the controller in the ECONOMY mode: when pressing the SEL 3 key the Mode LED flashes regularly 3 times a second. OUTPUT The heating set point is set to the upper point, while the cooling setpoint is set to the heating setpoint plus the dead band. The valve opening percentage is regulated by the P+I algorithm. Dirty Filter Signal and Alarm With the controller in normal operating mode the Mode LED turns on when the filter maintenance hours have been reached. This signal indicates that the filter must be cleaned. SIGNALS AND COMMANDS A A 30 After cleaning the filter, proceed as described below to reset the operating hours count down: 1. Press the SEL3 knob until the Mode LED briefly blinks 8 times. The filter operating hours are then reset to zero. 30 20 20 10 Honeywell 10 Daily valve drive SEL0 SEL2 Honeywell SEL2 SEL3 SEL1 SEL0 LED M ODE LED SUMMER/WINTER L E D FIL T E R LED MODE To prevent a possible valve blockage due to a prolonged standstill period, the valve is driven automatically at least once every 24 hours for 150 seconds. This function is enabled by parameter 19. Fig. 4 Room Unit The room unit has two signal LEDs that give different indications during the various operating and configuration phases. CHANGE OF THE ROOM UNIT FUNCTION MODES FOR ROOM UNITS WITHOUT A DISPLAY CHANGE OF SEASON ­ SUMMER / WINTER (BASIC MODEL ONLY) If Parameter #9 (summer / winter switching) is in the MANUAL mode, changing the season is possible by using the SEL1 KEY on the front panel. Press this key for 5 seconds until the colour of the selected season appears on the S/W LED for 5 seconds. After this, the LED will assume the appropriate operating mode. The default value of Parameter #9 is Manual. SUMMER/WINTER LED (BASIC MODEL ONLY): RED ON when the RFC is in the WINTER function mode. GREEN ON when the RFC is in the SUMMER function mode. RED or GREEN LED BLINKING (1 second ON, 1 second OFF) when the set point is satisfied, but the fan is still running, or when the valve is opening and the fan hasn't been started yet. ORANGE LED BLINKING (1 second ON, 5 seconds OFF) when the room temperature is in the dead band or the set point is satisfied, since the controller is in the COMFORT mode.
