Instruction Manual

EVC-2

Environmental Controller

Welcome to the future. The EVC-2 Environmental Controller
represents a new level of intelligent design and function in a simple
to use and reliable controller. It is 100% digital and programmable.
Separate Day and Night temperature & humidity setpoints are
critical for proper plant development.

The EVC-2 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, exhaust fan or heater.

The humidity is separately controlled and

can be set to either increase or decrease the

humidity to a specific level.

Like the temperature, there are separate Day and Night humidity settings

that provide remarkable control of critical humidity levels especially at

night.

• The EVC-2 coordinates the use of supplemental CO2 with the

temperature control function. It is the best and most cost effective

device on the market.

• It also has the ability to record and recall the Minimum and

Maximum temperatures and humidity. The built-in photocell allows

the uses to set separate Daytime and Nighttime temperatures &

humidity levels and also aids in controlling the CO2 operation.

• The remote temperature probe can be placed up to 16 feet from the

controller to more accurately control the temperature.

• It can control either a Cooling or a Heating device and either a

dehumidifier or a humidification device.

Specifications

Problem: The display reads Err SEn

The remote Temp & Humidity probe has been disconnected or is not
communicating with the unit. Check the cable and the remote sensor.
If resetting (OFF / ON) the power does not help, contact the factory.
(See below also)

Problem: The temperature and / or Humidity reading is erratic or
changing rapidly.

Certain devices such as Electronic (Digital) Ballasts and Ozone
generators produce a huge amount of electronic “noise”. If you are
operating these other devices, locate them as far away from the
controller as possible. Position the cables that connect the ballast to
the lamps away from the remote temperature probe on the controller.
To verify which equipment is affecting the temperature reading,
disconnect the other devices suspected of interfering with the
controller.
