2 It allows the user to maintain a specified target tem-perature by controlling the operation of ventilation and heating stages of variable speed fans can be connected to the Controller , aswell as two stages of constant-speed fans and two stages of either con-stant-speed fans or heating units. In addition, one of the constant-speed fanstages can be configured as a mist cooling main features of the TC5-2V4SA are as follows:THREE-DIGIT DISPLAYA three-digit display provides a high level of accuracy, allowing the user tospecify a Temperature to within one tenth of a degree (in Fahrenheit or Cel-sius units).PILOT LIGHTSP ilot lights indicating the state of outputs allow the user to monitor theoperation of the system without having to enter the VENTILATION CYCLEWhen ventilation is not required for cooling, the first stage fans can be oper-ated either continuously or intermittently to reduce the level of humidity andsupply oxygen to the AND MINIMUM VENTILATION SPEED CURVESThe Controller can be set to automatically change the Temperature set pointand the minimum ventilation speed over a given period of time in accordancewith the user's requirements by specifying a Temperature curve and a mini-mum ventilation speed curve with up to six different points OF TEN MOTOR TYPESThe variation in motor speed resulting from a change in voltage will dependon the make and capacity of the motor.

3 In order to achieve a high degree ofcompatibility between Controller and motor, the user can choose from amongten different motor types, thus ensuring that the correct voltage is OR CASCADING HEATERSHIGH/LOW Temperature ALARM OUTPUTFEATURES5TC5-2V4SA COMPENSATIONThe stage 1 minimum speed can be adjusted automatically as a function ofrelative humidity. As humidity increases, the minimum speed of stage 1fans increases proportionally to compensate for the FAN START-UPIn order to overcome the inertia of the ventilation system components andde-ice the fan blades in cold weather conditions, the Controller suppliesmaximum voltage to the variable speed fans during the 2 seconds immedi-ately following each CYCLEA de-icing cycle is provided for de-icing stage 2 variable-speed fans in coldweather INDEPENDENT Temperature PROBE INPUTSUp to four Temperature probes can be connected to the Controller in order toobtain a more accurate reading of the average room Temperature and afaster reaction AND OVERVOLTAGE PROTECTIONF uses are installed at the input and outputs of the Controller to protect itscircuitry in the case of an overload or CONTROLThe Controller can be connected to a computer.

4 Thus making it possible tocentralize the management of information and diversify control OF AIR INLET MOVEMENTIf the TC5-2V4SA is used in combination with a PF-5B Controller , the move-ment of the air inlets can be coordinated with the operation of the fans usinga potentiometer located on the panel drive. This allows the air inlets to beadjusted correctly, without the influence of uncontrollable factors such aswind or air from adjoining MODEA test mode allows you to simulate Temperature changes and verify control-ler LOCATION OF THE CONTROLSSETTINGSFUNCTIONS7TC5-2V4SA STATUS LEDS#OFFON1 UNLOCKED PARAMETERSLOCKED PARAMETERS2 FAHRENHEIT DEGREESCELSIUS DEGREES3 PROBE 2 DISABLEDPROBE 2 ENABLED4 PROBE 3 DISABLEDPROBE 3 ENABLED5 PROBE 4 DISABLED PROBE 4 ENABLED6NO HEATING STAGESHEATING71 HEATER2 HEATERS8 CASCADING HEATERSZONED HEATERS9 MIST OFFMIST ON10 RESERVED11 RESERVED12 RESERVEDINTERNAL SWITCHESThe internal switches are located on the inside of the front cover.

6 Onetype activates when current is cut off at its input, whereas the other activateswhen current is supplied at its input. For an alarm of the first type, use the NOterminal as shown on the wiring diagram. For an alarm of the second type, usethe NC WIRING MUST BE DONE BY AN AUTHORIZED ELECTRI-CIAN AND MUST COMPLY WITH APPLICABLE CODES, LAWSAND REGULATIONS. BE SURE POWER IS OFF BEFORE DO-ING ANY WIRING TO AVOID ELECTRICAL SHOCKS AND EQUIP-MENT INSTRUCTIONSCONNECTIONSOpen the latch and lift the cover. Remove the black caps located on each ofthe four mounting holes. Mount the enclosure on the wall using four sure the electrical knockouts are at the bottom of the enclosure in orderto prevent water from entering the Controller . Insert the screws in the mountingholes and tighten. Fasten the four black caps provided with the Controller ontothe four mounting holes. The enclosure must be mounted in a location thatwill allow the cover to be completely opened right up against the wall.

7 !WARNING9TC5-2V4SA relationship between the voltage supplied to a motor and its operatingspeed is described by a motor curve. This curve varies with the make andcapacity of the motor. The various motors available in the industry have beendivided into ten categories and the Controller has been programmed with adifferent motor curve for each of these categories. To ensure that thecontroller supplies the correct voltages, an appropriate curve must beselected for Stage 1 and Stage 2 according to the type of fan motors used. 1 Selecting a Motor Type for Stage 1 Refer to the list of motors enclosed with this user's manual to determine whichtype number (1 to 10) is appropriate for the motors the selection knob to STAGE1 BANDWIDTH/TIMER.

Set switches # 6 and # 7 to OFF touse both stages for cooling. Set switch # 6 to ON and switch # 7to OFF to use Stage 6 for heatingand Stage 5 for cooling. Set switches # 6 and # 7 to ON touse both stages for that if only one stage is used for heating, it must be Stage 1 Connecting the ProbesThe Controller is supplied with one Temperature probe connected to input# 1. Up to three additional probes can be connected to the Controller in orderto obtain a more accurate reading of the average room Temperature and afaster reaction inputs # 2, 3 and 4 to connect additional probes, as shown on thewiring diagram : Probes operate at low voltage and are isolated from the sure that probe cables remain isolated from all high voltage sources.

9 Inparticular, do not route the probe cables through the same electrical knockoutas other cables. Do not connect the shield from the probe cable to a terminalor a are used to activate or deactivate the additional probes connectedto the each additional probe by settingthe appropriate switch to ON: Switch # 3 activates the probe connected to input # 2. Switch # 4 activates the probe connected to input # 3. Switch # 5 activates the probe connected to input # PROBES345ON12TC5-2V4SA 2 Extending the ProbesEach probe can be extended up to 500 feet (150 meters). To extend a probe:nUse a shielded cable of outside diameter between and in( and mm) (the cable dimensions should not be under 18 AWG) to ensure the cable entry is liquid tight. Do not ground is preferable to solder the cable joint to ensure a proper contactbetween the two : Do not run probe cables next to other power cables. Whencrossing over other cables, cross at 90.

10 3 Defective ProbesIf a defective probe is detected, the Defective Probe Pilot Light turns on. Theroom Temperature shown on the display is then the average temperaturemeasured by the probes in working condition. The Controller will operateaccording to this identify the defective probe:nSet the selection knob to ROOMTEMPERATURE . The roomtemperature is the push-button. If theprobe connected to input # 1 andsupplied with the Controller is notdefective, the letters"PR1" aredisplayed, alternating with the on/off state of the probe and the tem-perature measured by the the probe is defective, the let-ters "PR1" are displayed, alter-nating with the state of the probe13TC5-2V4SA the letter "P".For each additional probe connected to the Controller :nPress the push-button once again. If the probe is not defective, theletters "PR#" (where # is the number of the input to which the probeis connected) are displayed, alternating with the on/off state of theprobe and the Temperature measured by the probe.
