Instruction Manual
EVC-1
Environmental Controller
Temperature… Humidity & CO2. What do they have in
common? They are all environmental conditions inside a growing
area that need to be controlled for successful gardening.
The EVC-1 Environmental Controller controls all that and more. If
you want a simple-to-use and reliable controller without spending
hundreds of $, check out the EVC-1.
The EVC-1 has been designed to maintain
a specific temperature and humidity within
an area. It controls temperatures by
operating a device such as an air-conditioner
or exhaust fans.
The humidity is separately controlled and
can be set to either increase or decrease the
humidity to a specific level. It can also
coordinate the use of supplemental CO2 with the temperature control
function. It is the best and most cost effective “analog” controller on the
market. Here is some of it’s features and what it can do:
• Control Temperature & Humidity separately OR together. A selector
switch let YOU customize the controller.
• Can either increase OR decrease the humidity level. Again… a selector
switch let YOU customize the controller.
• Built-in Photocell determines whether it is Day or Night. Activates
CO2 device only during Daylight hours.
• A built-in feature that is very useful is the Night Device outlet.
Connect your Night only device into this outlet. Control an exhaust
fan, heater or dehumidifier...
• Heavy-duty #14 AWG power cable. Fuse protected by a 15-amp
e-settable circuit breaker.
• Built using only the best UL or CSA certified components.
• “Over-built” with over-rated components such as 30-amp relays, 20-
amp power switches and terminals.
• The EVC-1 carries a full 3-YEAR warranty!

Troubleshooting
Specifications
Problem: The unit does not power up at all.
Check and reset the circuit breaker. A small red button will pop out at
the bottom of the unit, press it in to reset. If the problem continues,
reduce the number of devices connected to the unit.
Problem: The Temperature or Humidity control function do not
seem to be working correctly.
The user can select 3 different modes. Refer to Operating the EVC-1
for a full explanation of the modes and how they affect operation.
Problem: The CO2 device does not turn ON.
2 things affect the CO2 outlet. The photocell must receive enough
light to activate the CO2. The Temperature Device outlet will
over-ride (shutoff) the CO2 Device outlet. While the Temperature
control device is ON, the CO2 Device will remain OFF.
Problem: The circuit breaker trips repeatedly.
The entire unit can control up to 15-amps @ 120 volt. If the circuit
breaker keeps tripping, you either have one device connected that is
faulty or there is too much “load” on the unit. Reduce the number /
amount of devices connected.
Problem: The Humidity control function seems to be working
reverse.
The humidity can be set to either increase or decrease the Humidity
level. Refer to Operating the EVC-1 for a full explanation of the
Humidity modes and how they affect operation.
Problem: Both the Temperature & Humidity device turn ON at
the same time.
The Temperature & Humidity can either operate independently or
they can be combined to function together. Refer to Operating the
EVC-1 for a full explanation of the Humidity modes and how they
affect operation.
Problem: The Temperature & Humidity device do not turn ON at
the same time.
