Sentinel EVC-1 Environmental Controller

The EVC-1 provides extreme flexibility in reliable solid-state environmental controller. Selectable CO2, temperature and humidity modes allow the user to control temperature and humidity separately or together. Built-in photocell activates C02 device during the day. Night device outlet can control an exhaust fan/sulfur burner, etc.

• 15 amps @ 120 VAC
• 32 to 120 degrees F
• 0-99% rH
• +/- 2’ F
• +/- 7% rH

Comes With:

• Familiar "analog" controller.
• Built-in photocell controls CO2.
• Heavy gauge #14 AWG cables and wire.
• Super-duty 30-amp relays for long life.
• Power switch and re-settable 15-amp circuit breaker provides over-current protection.

Benefits:

• The EVC-1 is a very flexible and useful controller.
• It combines the ability to control temperature, humidity, a CO2 device and a Night device all in one neat package.
• The user can select one of 3 different modes and feel safe using it with a re-settable table circuit breaker and heavy-duty components and wiring.
• Simplest to use, easy to own.
• 3 year warranty.

How to use:

• The unit comes with a metal bracket that is first attached to a wall. Secure the bracket to the wall with 2 screws. Then use the 2 thumb screws to secure the enclosure to the bracket.
• The device(s) that will be controlled by the EVC-1 must be 15-amp or less COMBINED load. There are FOUR outlets (receptacles) on the EVC-1 One of them is used to control the temperature devices like AV or fans. Another receptacle is to connect your humidity device like a humidifier or dehumidifier. A CO2 receptacle is provided that will activate a CO2 device during the day, with or without coordination with the temperature control device. The 4th receptacles called "Night Device" activates a device like dehumidifiers, exhaust fans etc. that is only to be operated at Nighttime. It has a built-in photocell that senses whether it is Day or Night.
• The unit requires a 15-amp power supply. Plug the power cable into a standard wall outlet. The built-in circuit breaker will protect the unit from overloads. Select the mode of operation you want the unit to ,./function with, set your temperature and humidity level and then... sit back and let the EVC-1 do the work for you.


• For indoor growing, cooling devices such as ventilation fans or air-conditioners connect to the temperature device.
• Dehumidifier or a humidifier can be connected to the humidity device receptacle.
• Heaters for cooler climate greenhouses can be connected to the night device receptacle
• Connect your compressed CO2 solenoid / regulator assembly OR a CO2 generator to the CO2 device receptacle.
