    FEATURES The TC5-8SDA is an electronic device used for environmental control in livestock buildings. It allows the user to maintain a specified target temperature by controlling the operation of ventilation and heating equipment. Six stages of constant-speed fans or mist units and two stages of either constant-speed fans or heaters can be connected to the controller.
  • Page 5 The controller can be connected to a computer, thus making it pos- sible to centralize the management of information and diversify control strategies. TEST MODE A test mode allows you to simulate temperature changes and verify controller performance. TC5-8SDA rev.03...

  • Page 26: Outside Temperature Compensation

    TC5-8SDA OUTSIDE TEMPERATURE COMPENSATION The TC5-8SDA has the capability of automatically adjusting the running time of the minimum ventilation fans as a function of outside temperature. As the weather gets colder, the on time is decreased gradually to compensate for the change. This can help reduce costs by reducing the ventilation when it is not required.
  • Page 27 NOTES: i) When the compensation factor is activated, the lowest time on value allowed after zero is 30 seconds. ii) The controller recalculates the compensation factor at the end of the time on portion of each timer cycle. TC5-8SDA rev.03...
