Aerotech® AeroSpeed 1.3 High-Performance Running Shoes - Lightweight & Breathable for Men & Women - Perfect for Marathon Training, Gym Workouts & Daily Jogging

Used to regulate the environment in livestock buildings, the Aerotech AeroSpeed 1.3 maintains your desired temperature in the facility by controlling the operation of ventilation and heating equipment.  One stage of variable speed cooling fans can be connected to the controller, as well as one stage of either constant-speed fans and two stages of either constant-speed fans or heating units. The last cooling stage can be configured as a mist cooling stage.

Features of the ST 5121:

• Three Digit Display
  Provides a high level of accuracy, allowing you to specify a temperature to within 1/10 of a degree (in Fahrenheit or Celsius units)
• Pilot Lights
  Indicate the state of outputs allow you to monitor the operation of the system without having to enter the building
• Minimum Ventilation Cycle
  When ventilation is not required for cooling, the first stage fans can be operated either continuously or intermittently to reduce the level of humidity and supply oxygen to the room
• Temperature & Minimum Ventilation Speed Curves
  Can be set to automatically change the temperature set point and minimum ventilation speed over a given period of time in accordance with your requirements by specifying a temperature curve and a minimum ventilation speed curve with up to 6 different points each
• Choice of 5 Motor Curves
  The variation in motor speed resulting in a change in voltage will depend on the make and capacity of the motor. In order to achieve a high degree of compatibility between controller and motor, you can choose from among 5 different motor curves, to ensure the correct voltage is supplied
• Full Speed Fan Start-Up
  To overcome the inertia of the ventilation system components and de-ice the fan blades in cold weather conditions, the controller supplies maximum voltage to the variable speed fans for 2 sec immediately following each start-up
• 4 Independent Temperature Probe Inputs
  Up to 4 temperature probes can be connected to obtain a more accurate reading of the average room temperature and a faster reaction time
• Overload and Overvoltage Protection
  Fuses are installed at the input and outputs to protect its circuitry in the case of an overload or overvoltage
• Computer Control
  Can be connected to a computer, making it possible to centralize the management of information and diversify control strategies

Several Models To Choose From. Features of All Models:

• Fully adjustable temperature and ventilation curves
• Variable speed outputs have optional timer option
• Minimum, maximum temperature recordings
• 12' sensor included
• 120/240 volt
• 10 amp maximum fan load

• Enclosure:
  ABS, moisture and dust-tight
• The room temperature where the controller is located MUST ALWAYS REMAIN between 32° F and 104° F

Factory Settings:

These initial parameter settings will not be retained in the controller's memory. Each new setting will replace the preceding one.
If the power supply is cut off, the last parameter settings will be retained in the memory until the power is restored.
