  • Page 24 TC5-1N4F1A If room temperature rises: • When room temperature < Set Point, stage 1 fans run at minimum speed according to the minimum ventilation cycle. • At Set Point: stage 1 fans stop operating according to the minimum ventilation cycle and increase in speed as the room temperature rises.

  • Page 25: Minimum Ventilation Cycle

    TC5-1N4F1A INIMUM VENTILATION CYCLE When the room temperature is below the set point, the Stage 1 fans operate according to the minimum ventilation cycle. Running the fans even though ventilation is not required for a cooling purpose is useful to reduce humidity levels and supply oxygen to the room.

  • Page 26: 1 - Minimum Speed/Curve

    TC5-1N4F1A Adjusting Minimum Speed The minimum speed can be adjusted between 10 and 100% of the full speed of the fans. Set the selection knob to STAGE 1 — MINIMUM SPEED/CURVE. The current minimum speed for Stage 1 flashes on the display.

  • Page 27: Humidity Compensation

    TC5-1N4F1A UMIDITY COMPENSATION The stage 1 minimum speed can be adjusted automatically as a function of relative humidity. As humidity increases, the stage 1 minimum speed in- creases proportionally to compensate for the change. At humidity levels at or below the humidity set point, stage 1 minimum speed is equal to the normal uncompensated speed.
  • Page 28 TC5-1N4F1A Viewing Relative Humidity The relative humidity is expressed as a percentage. Set the selection knob to STAGE 1 — HUMIDITY CON- TROL. The current relative humidity is displayed. Turn the adjustment knob clockwise by one notch. The minimum humidity flashes on the display, alternating with the letters "Lo".

  • Page 30 TC5-1N4F1A INIMUM VENTILATION SPEED CURVE The user can define a minimum ventilation speed curve to adjust the Stage 1 minimum speed automatically over a given time period. Each curve is defined by six points. Each point specifies a day number and a fan speed for that day.
  • Page 31 TC5-1N4F1A Interaction Between Temperature and Minimum Speed Curves • The minimum speed curve can be activated only if the tempera- ture curve is already activated • All points of the minimum speed curve other than the first one are automatically given day numbers identical to those specified for the tem- perature curve.
  • Page 32 TC5-1N4F1A • If you activated the temperature curve yesterday, the current day number of the temperature curve is d6. Therefore, if you activate the mini- mum speed curve today, it will effectively be in operation in 4 days, when the current day number of the temperature curve reaches d10. In the meantime, the fans will run at the specified single minimum speed (see example 2).
  • Page 33 TC5-1N4F1A Specifying Minimum Speed Curve Set the selection knob to STAGE 1 — MINIMUM SPEED / CURVE. The current minimum speed flashes on the display. Press the push-button. The word OFF is displayed, indicating that the minimum speed curve is de- activated.
