The EVC-1 Environmental Controller controls temperature and humidity as well as having rudimentary Co2 control and a Night Device outlet. 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 re-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!
