BASIC DESCRIPTION
The APCET2 is a temperature controller that can be used as a cooling OR a heating controller. Once the
APCET2 is connected to a power source, and the cooling or heating device is connected to the APCET2
power outlet, the device connected will be automatically controlled by the settings on the APCET2.
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 APCET2.
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 APCET2 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.
The Power lamp lights showing power is present, and the On lamp indicates the outlet is energized.
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. Move
switch to desired position.
Once the correct mode is selected, the user can then set the desired temperature settings using the
two knobs normally.
After this is completed, you have the option to "lock" the settings into memory, which prevents any
changes to the cycle until the unit is unlocked.
CHANGING SETTINGS
The switch on the front of the unit allows the product to function during the day, the night, or 24
hours. The photocell will automatically use the correct setting depending on the lighting level. 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.
