1. FANS WITH TEMPERATURE AND SPEED CONTROLLER MODULE TSC The TT U fans fig 25 enable automatic impeller speed air flow control depending on the air temperature in the duct The n index models are equipped with a remote temperature sensor on a 4 m extension cable All the fan models with TSC module are equipped with a power cable The front panel has the following control knobs pre set impeller speed thermostat operating threshold The yellow light indicator on the front panel shows thermostat operation Timer Operation Algorithm Set the desired thermostat temperature operating threshold by turning the thermostat control knob Set the desired impeller speed air flow by turning the impeller speed control knob On reaching the pre set air temperature and exceeding the thermostat operating threshold the fan motor switches to the maximum speed maximum air flow The fan motor switches to the pre set speed as the temperature drops below the pre set thermostat operating threshold The switching delay function is provided to prevent frequent fan speed changes due to crossing the temperature threshold especially if the operating temperature is equal to the thermostat threshold value The switch off delay operating logic has two versions TT U Temperature sensor delay algorithm On exceeding the pre set temperature 2 C above the thermostat operating threshold the fan2. INLINE MIXED FLOW FANS VENTS TT SERIES USER S MANUAL vens www ventilation system com 2011 A Read this manual carefully before installation and commissioning of the unit READ THE INSTRUCTIONS CAREFULLY TO REDUCE THE RISK OF FIRE ELECTRIC SHOCK OR INJURY Compliance with the manual requirements ensures reliable fan operation throughout the entire service life This user s manual contains technical and operating logic description mounting requirements servicing and maintenance guidelines for the inline mixed flow fans TT designed for supply or exhaust ventilation of premises heated during winter time The fans are made of plastic The delivery set includes 1 Fan 1 pce 2 Screws and dowels 4 pcs 3 User s manual 4 Packing box The fans are powered by AC 220 240V 50 60 Hz single phase current and designed for continuous operation always connected to the electric mains Ingress protection rating IP X4 The fans are designed for operation at the temperature range from 0 C up to 40 C The air temperature in the ventilation system must not exceed 45 C Store the fan in manufacturer s packaging in a ventilated room at temperatures between 5 C and 40 C and relative humidity not more than 80 at 25 C The fans are suitable for connection to 100 125 150 160 200 250 315 mm air ducts The S index fan modifications are equipped with a high power motor Air flow

4. direction should match the direction of the arrow on the fan casing The fans are designed both for horizontal or vertical installation and are suitable for individual installation of one unit fig 2 or two or more units mounted in series or in parallel fig 3 The mounting kit components are delivered upon request An air duct at least 1 meter long must be connected to the intake flange in case of horizontal fan mounting a cowl must be installed in case of vertical mounting The intake flange must always be connected to an air duct Mounting sequence is shown in fig 4 11 The wiring diagrams are shown is fig 12 16 Designations QF automatic circuit breaker fig 1 S external switch fig 1 X input terminal Automatic circuit breaker Automatic circuit breaker designation External switch ON OFF Due to the constant improvements the design of some models may slightly differ from those described in this manual External switch designation Any electric connections adjustment servicing and repair works are allowed only after the unit is disconnected from power mains Mounting and maintenance are allowed for duly qualified electricians with valid electrical work permit The single phase power grid must comply with the acting local electrical norms and standards The fixed electrical wiring must be equipped with an automatic circuit breaker The fan must be connected to the power grid thr
5. ith the unit shall not be covered by the warranty No warranty for compatibility of the fans with other producers goods Only manufacturing defects are covered by the warranty terms All the defects and faults resulting from mechanical effect during operation process or natural wear and tear shall not be covered by the warranty conditions The malfunctions caused by violence of operation servicing and maintenance guidelines either by Customer or third parties or caused by unauthorized design modifications shall not be covered by warranty NO LIABILITY FOR THE RELATED DAMAGES The manufacturer is not responsible for any mechanical or physical damages resulting from the manual requirements violence the unit misuse or gross mechanical effect The indirect damages such as re installation or re connection of the unit direct or indirect losses etc related to the unit replacement shall not be indemnified Mounting dismantling connection disconnection and regulation of the unit shall not be covered by the warranty The contractor in charge for quality of mounting electric mounting and adjustment works shall be responsible for the warranty thereof In any case the indemnity amount shall not exceed the actually paid value for the defective unit price
6. motor switches to the maximum speed The fan motor reverts to the pre set speed as soon as the duct temperature drops 2 C below the thermostat operating threshold This algorithm is used to maintain the desired temperature up to within 2 C The fan speed changes are rare in this case TT U1 Timer delay algorithm On reaching the pre set air temperature the motor switches to higher maximum speed and the delay timer starts the 5 minute countdown The fan motor reverts to the previous speed not earlier than 5 minutes after the duct air temperature drops below the thermostat pre set threshold This algorithm is used to maintain the desired air temperature precisely In this mode the fan motor changes its speed more frequent as compared to the temperature sensor delay mode but in any case the switching cycle does not exceed 5 minutes pre set impeller speed control knob electronic thermostat operating threshold control knob m UE UD 10 MAINTENANCE Maintenance fig 26 30 means periodic cleaning of the surfaces from dust and dirt The impeller blades require thorough cleaning every six months To clean the impeller blades detach the clamps remove the casing and wipe the blades with warm water and mild detergent solution Avoid water dripping on the motor while cleaning the blades fig 31 MALFUNCTIONS AND TROUBLESHOOTING 1 Fan does not get started broken electric circuit Check the cable
7. ough the automatic circuit breaker QF The gap between the breaker contacts on all poles must be not less than 3 mm The overcurrent value shall be equal to the fan current consumption and is indicated on the fan rating plate Before installation check the fan for any visible damages of impeller and casing The casing internals must be free of any foreign objects which can damage the impeller blades Misuse of the device or any unauthorized modifications are not allowed The unit is not to be used by children and persons with reduced physical mental or sensory capacities without proper practical experience or expertise unless they are controlled or instructed on the unit operation by the person s responsible for their safety Do not leave the children unattended to avoid their playing with the device Take steps to prevent ingress of smoke carbon monoxide and other combustion products into the room through open chimney flues or other fire protection devices Sufficient air supply must be provided for proper combustion and exhaust of gases through the flue chimney of fuel burning equipment to prevent backdrafting The transported air must not contain any dust or other solid impurities sticky substances or fibrous materials Do not use the fan in the environment containing hazardous or explosive materials and vapors i e spirits gasoline insecticides etc Do not close or block the intake and exhaust vents not to disturb the natu
