Hydrofarm APCET autopilot Mode D'emploi page 2

BASIC DESCRIPTION
The APCET is a temperature controller that can be used as a cooling OR a heating controller. Once the
APCET is connected to a power source, and the cooling or heating device is connected to the APCET
power outlet, the device connected will be automatically controlled by the settings on the APCET.
The user can choose to have different day and night temperature settings which will be automatically
switched to the correct mode by the built-in photocell. The knobs make it easy to adjust the settings
and provide a quick visual verification of the current set-points. The LEDs on the front of the unit will
turn ON and OFF to show the user the current conditions of the APCET.
NOTE: This unit is water-resistant, however... Keep it away from water! It is NOT WATERPROOF.
INSTALLATION
Plug the unit into a standard NEMA 5-15 wall outlet. A 120V power supply is required. For more
permanent installations, the mounting tab at the top of the unit can be secured to a wall.
Ensure that the device being connected to the APCET has the proper voltage and will not exceed the
maximum amperage rating of this unit. Connect the device to be controlled into the power outlet on
the front of the unit.
NOTE: If you are trying to control multiple devices, a power expansion module can be used to
increase the amount of power load that can be controlled.
WARNING: DO NOT EXCEED THE MAXIMUM RATING
SELECTING COOLING OR HEATING MODE
Before using the unit, the user must decide if they are using it for a cooling or a heating control. The 2
knobs on the unit are used to select the desired mode.
To select Cooling: Connect the unit to power. Rotate both knobs fully COUNTER-clockwise. After a
couple of seconds, the LEDs on the front of the unit will start flashing On/Off. After the LEDs stop
flashing, the selected mode is indicated by the LED that remains illuminated. (Verify that the Cool
mode is ON. Once the correct mode is selected, the user can then set the desired temperature settings
using the two knobs normally.)
NOTE: The above paragraph describes the Cool mode. When in Cool mode, the setting is the
maximum temperature of the area to be controlled. For Heat mode, the setting chosen will be the
minimum temperature of the area to be controlled.
To select Heating: Connect the unit to power. Rotate both knobs fully clockwise. After a couple seconds
the LEDs on the front of the unit will start flashing On/Off. After the LEDs stop flashing, the selected
mode is indicated by the LED that remains illuminated. (Verify that the Heat mode is ON.)
Once the correct mode is selected, the user can now set the desired temperature settings using the
two knobs normally.
CHANGING SETTINGS
Use the knobs on the front of the unit to adjust the DAY and the NIGHT temperature settings.
The photocell will automatically use the correct setting depending on the lighting level. When the
temperature of the area exceeds the temperature set-point, the device connected to the power outlet
will be activated. Since the temperature control has a deadband setting of 3°F, the power outlet will
remain activated until the temperature is lowered by 3°F. When the outlet is powered, the Output ON
LED will be ON.
