Basic description
The APCETHD is designed to control humidity, temperature
and CO2. The controller has four (4) receptacles and a remote
combination probe with highly accurate temperature, humidity
and light sensors. The remote combination sensor is designed
to quickly react to changes in the growing area and to resist EMI
/ EFI from electronic ballasts. The remote sensor can be placed
up to 15 feet from the controller.
Note: An optional 15 ft extension cable can be purchased to
allow the user to place the remote sensor up to 30ft from
the controller.

Installation
Secure the unit to a wall.
Determine the best location for the remote probe. Place the probe
in an area with good air movement preferably at plant height.
Avoid placing the probe in direct sunlight or under direct HID
Lighting.
NOTE: Do not place the sensor probe where it will
come in to contact with water. The unit is not
waterproof!
The remote probe has a quick disconnect to easily remove or
connect the probe. Secure the quick disconnect to the unit by
securing the QD screw to the unit.
Plug the power cable into a standard NEMA 5-15 wall outlet. A
120 volt power supply is required.
Ensure that all of the devices being connected to the controller
have the proper voltage and will not exceed the maximum
amperage rating of this unit.
Note: Now is the time to customize your settings prior
to connecting any equipment.

Error LEDs
The APCETHD is smart enough to monitor the temperature and
humidity levels and to alert the user to a problem with any of the
devices connected to the APCETHD. Here is how it works.
As the unit functions normally, the environmental conditions
(temp & humidity) will be slowly but steadily changing. These
small changes are detected by the controller.
If the controller does not detect a slight change in one (or more)
environmental conditions within a 1-hour period, the unit will de-
activate the affected output and the appropriate green Error LED
will be flashing to indicate which device may have a problem.
This safety feature is extremely important and useful to
eliminate “runaway” conditions which could result in crop damage
or other more serious problems.
If any of the Error LEDs are blinking, the user should refer to the
example below to help identify the actual cause of the error.
* EXAMPLE: The Cooling error LED is flashing, it means that
the device connected to the Cooling output either did not
turn on OR that there is a problem with the temperature
sensor. Check the cooling device for proper operation and
verify the remote sensor is reading properly.
Note: To reset an error, press the Enter / reset button.

Q & A
What if my temperature is reading high? Make sure the remote
probe is not in direct lighting from HID lights or sunlight.
Do I need to calibrate my humidity sensor? No. like the
temperature sensor, the humidity sensor is digital and does not
require calibration.
Why is the display reading Err SEn? The remote probe is not
connected and/or communicating with the controller. Check the
quick-connect cable and that the remote probe is getting power.
*Contact the factory for more info.
What if one of the small green Error LEDs are on? One or
more environmental conditions are not acting correctly. Refer to
the Error LEDs sections to diagnose the problem.
What if the CO2 timer is not keeping correct time? The battery
may need to be replaced. The lithium battery has an average life
of 5 years. Battery is a lithium CR1220 3 volt.
What if there is no power? Reset the power switch (circuit
breaker). If this continues reduce the number of devices
connected or use a power multiplier / expander to control devices
with larger amperage.
