Page 2: Main Features
INTRODUCTION Thank you for purchasing the AegisTEC touchscreen environmental controller. The AegisTEC is designed for ease of installation and operation, while still addressing the unique challenges of greenhouse environmental control. The system can coordinate and control ventilation curtains, light deprivation curtains, heaters, and fans. - Page 3 WARNINGS Read instructions completely before beginning your installation. Familiarize yourself with this unit and compare what you received with these instructions. Always wear eye and ear protection. Always use gloves and other necessary safety equipment. Metal can be sharp, handle with care to avoid injury. All electrical connections must be made by a qualified, licensed electrician.

Page 5: Overview
OVERVIEW Theory of Operation The key to easily and successfully setting up your AegisTEC environmental controller is understanding how the control outputs are assigned by the controller and how they are used to control your greenhouse. The control circuitry is contained on two boards. The first one is the microcontroller which includes the touchscreen, and the second is the relay board. - Page 6 OVERVIEW The relay board pictured on the next page contains ten output terminals configured in three basic ways. • Terminals 1, 2, and 3 are configured in pairs, with a 24 volt DC output to drive motors or actuators toggled between the A and B terminals. This is done because the motors are run in both the forward and reverse direction to open and close curtains or vents.
- Page 7 OVERVIEW...
- Page 8 3A and 3B are independently operated by their relays, providing a 24 volt DC output to control external relays such as are found in Advancing Alternatives contactor box 42-CB4. It can be seen that terminals 1A through 3B can be used, through proper...
- Page 9 OVERVIEW Contact locations are assigned by the controller during user configuration. Vent assignments are for motors or actuators. The first assigned device(s) is assigned to terminals 1A/1B and 2A/2B and will have the designation “Vent #1”, or, if no vents are assigned, “Fan #1”. This is where devices that work in pairs should be connected since there are two sets of terminals operating together, each with its own circuit breaker.

Page 12: Connecting The Temperature Sensor
INSTALLATION Connecting the Temperature Sensor Connect the sensor wires to the terminals labeled “temperature sensor”. The temperature sensor has two wires. Connect the red wire to the positive terminal and the white wire to the negative terminal. Secure but do not overtighten (3 in-lb max). -
Page 13: Connecting The Humidity Sensor
INSTALLATION Connecting the Humidity Sensor Place the humidity sensor in the middle of the structure and at a height that best represents the average humidity at crop level. If you have the optional second temperature sensor installed, you must remove it before installing the humidity sensor wires. -
Page 14: Connecting The Low Voltage Ventilation Motors
INSTALLATION Connecting the Low Voltage Ventilation Motors The AegisTEC includes a 350 watt, 14.5 amp, 24 volt DC power supply. It is prewired to operate three 24 volt DC ventilation motors. Vent zone #1 will operate motors #1 and #2 (terminals 1 and 2) simultaneously. Vent zone #2 will operate motor #3 (terminal 3). - Page 15 INSTALLATION...

Page 17: Connecting The Heaters
INSTALLATION Connecting the Heaters Do not directly connect the The AegisTEC thermostatically controls heaters. 110/220 volt AC heater wires to the control board. A high voltage connection can cause a fire risk and void the warranty. Heaters produce their own 24 volt AC signal using an internal transformer. -
Page 18: Connecting The Anemometer
INSTALLATION Connecting the Anemometer The anemometer is used to close curtains in high wind conditions. It has three 18-24 gauge AWG wires that connect to the wind sensor terminals. Connect the red wire to the 24 volt positive terminal, the white wire to the input #2 terminal, and the black wire to the 0 volt negative terminal. -
Page 19: Connecting The Rain Sensor
INSTALLATION Connecting the Rain Sensor The rain sensor detects water droplets on the lens. Mount the sensor on the structure at a height relative to the desired sensitivity, with a higher sensor less sensitive than a lower one. Match the rain sensor wire to the corresponding terminal by color. -
Page 20: System Setup
SYSTEM SETUP Main Screen The main screen shows the status of the controlled zone. You can see the temperature and the status of the relays. Touch the center of the screen to access the settings menu. Touch the bottom row of buttons for manual overrides. -
Page 21: Overrides
SYSTEM SETUP Overrides The general override buttons allow you to override any timed setting. Relay Overrides By touching the relay buttons on the main screen, you can access individual manual control, where you can select the relay status you want. In auto mode, the controller will perform as configured. -
Page 22: Configuring The Controller
SYSTEM SETUP DIF Overrides DIF allows you to create alternate temperature setpoints during a 24 hour period. A typical DIF technique drops the temperature in the morning hours. A second DIF period could be used to amass solar energy before sunset. The control status is displayed under the clock as either Primary, DIF, or LiDep. - Page 23 SYSTEM SETUP Read through the manual to familiarize yourself with the available functions and have a plan that you will enable through the configuration menu and system settings. It is important, when setting parameters or making changes in the menu, to always touch “Save” before moving to the next parameter. By touching the center of the main screen, you will access the settings screen.

Page 24: Settings
SETTINGS Configuration Setup Description Vent channels each operate a 24 volt DC motor and Min - Max use two output terminals per channel in order to run 0 - 3 the motors in both directions. Low voltage rotary gear motors for curtain vents and low voltage linear actuators to lift hinged vents are controlled as vent channels. - Page 25 SETTINGS Description This sets the number of rotations needed for the Default wind sensor to calculate the wind speed. Set to 25 for miles per hour or 17 for kilometers per hour. Use this to set the type of sensor you have Default connected as a second sensor.
- Page 26 SETTINGS Description Default The controller factory default is set to Fahrenheit. Set this to 1 if Celsius is desired. Use this screen ONLY if you suspect a problem with the configuration and want to start over. This will erase all your settings and revert to the factory settings when the unit was new.

SETTINGS Zone Parameter Setup By touching the center of the main screen, you will access the settings screen. The system settings menu is where input values are assigned to the environmental systems to be controlled. What is visible in this menu is based on the information entered into the configuration menu. -
Page 28: Curtain Settings
SETTINGS Curtain Settings Description When the greenhouse temperature reaches the Min - Max setting entered here, the specific vent (1-3) will 1° - 99° open. The closing temperature is related to the Default opening temperature by the ventilation temperature gap entered in P60. 60°... - Page 29 SETTINGS Description Default This is how long the vent will wait in minutes as described in P58. This is the difference in between the temperature that causes the vent to open and the temperature that causes it to close. Setting this too low causes Default the vents to open and close unnecessarily.
- Page 30 SETTINGS Description Set this to the wind speed that should cause vent Default closure. There is a separate setting (P85) for the wind speed that allows the vents to reopen. This assumes the connection of an anemometer. Set this to the speed to which the wind must reduce for the vents to reopen.
