VALVE FUNCTION The valve functions are adjusted with the DIP switches under the connection cover. FlowCon FH Switch #1 : Auto cycle ON/OFF 6 Ipfrtehveenptlasntht espveaclvifeicafrtoiomnsjapmemrminitgitw, thheenatuhteo vcaylcvlee icsannobt emaocvteivdaftoerdadluorninggercopmermioidssoiof nininagct.ivAituyt,oec.gy.clfeor 5 heating systems during the summer. When the auto cycle is activated, the actuator will perform 50% 4 stroke cycle if no stroke movement has occurred during a 3-weeks period. Factory setting = OFF. 3 Switch #2 : Analog 2-10V DC / 0-10V DC 2 Setting control range by the continuous actuating signal 0-10V DC or 2-10V DC. 1 Factory setting = 0-10V DC. Switch #3 : Normally open / Normally close Setting actuating direction with 10V DC control signal to “valve open” or “valve closed” as well as the position feedback. Factory setting = Normally closed; 0V DC = valve closed. Switch #4 : Equal % control / Linear control Setting of actuating control curve to either equal percentage or linear control. Factory setting = Linear control. Switch #5 : has no function. Switch #6 : Re-calibration Setting is indifferent, but flipping the switch will start re-calibration. After re-calibration the actuator will automatically go into normal operation. FlowCon FH-BUS Switch #1 : BIT 0 ON/OFF 8 For bus address setting. Setting bit 0 to either 1 (=ON) or 0 (=OFF). Factory setting = OFF. 7 Switch #2 : BIT 1 ON/OFF 6 For bus address setting. Setting bit 1 to either 1 (=ON) or 0 (=OFF). 5 Factory setting = OFF. 4 Switch #3 : BIT 2 ON/OFF For bus address setting. Setting bit 2 to either 1 (=ON) or 0 (=OFF). 3 Factory setting = OFF. 2 Switch #4 : BIT 3 ON/OFF 1 For bus address setting. Setting bit 3 to either 1 (=ON) or 0 (=OFF). Factory setting = OFF. Switch #5 : BIT 4 ON/OFF For bus address setting. Setting bit 4 to either 1 (=ON) or 0 (=OFF). Factory setting = OFF. Switch #6 : BIT 5 ON/OFF For bus address setting. Setting bit 5 to either 1 (=ON) or 0 (=OFF). Factory setting = OFF. Switch #7 : Bus protocol Setting bus protocol selection to either MODbus (=ON) or BACnet (=OFF) Factory setting = OFF. Switch #8 : Terminating resistor Setting terminating resistor to either active (=ON) or inactive (=OFF). Factory setting = OFF.

Switch #6 : Electrical override Setting override function to ON and the actuator will open valve fully. When set to OFF again, the actuator will re-calibrate and thereafter go into normal operation mode.
