Environmental Controllers » Harvest Master

Controls night and day length, temperature and humidity control, plus controls up to 8 devices (or 7 and a cycle timer), for a balanced climate. All models come as a complete kit. The kit includes controller, sensors, remote relay switches. Sensors are hight accuracy types, for temperature, humidity and CO2. 3 remote relay switches are included for lights and heaters to put on different electrical circuits.

The 'Pro' model is the same as the Climate model plus a CO2 sensor and 4th relay switch.

The "Pro Plus" model is the same as the Climate Plus model plus 8 additional inputs & outputs, to control advanced functions including automation of alarms which can drive the optional "Text Message" (product no. 703335) option.

CO2 EASi is intelligent control of CO2 and at the same time, an intelligent Temperature controller where the COOL KIT is attached for additional automatic control of cooling units and or fans. As soon as CO2 is switched ON, it learns how CO2 enrichment works in your room, including whether you use bottle or burner. Continuous learning and adjustment all day, every day. CO2 EASi will understand, calculate and predict enrichment operations for optimum growth.

Consumption: Automatic calculation and display of CO2 consumption rate, with predicted bottle life remaining.

Efficiency Monitoring: Shows percentage of optimum CO2 enrichment time achieved. Automatic and continuous evaluation of cooling and exhaust system efficiency. Identifies where improvements can be made for more growth, increased yield, reduced CO2 use and lower power costs.

Relay switches for you to plug and run: lights, fans, heaters or any other timed device.

Each relay is rated to switch 15-amps. 120 volt AC or 240 volt AC

Relays can be daisy-chained with "Y" connectors to permit up to 6 relay switches to be switched ON by a single Harvest-Master® output signal (for up to 6 light arrays for example).

NOTE: A maximum of 7 relay switches per controller output

• USA. 240v, 2-pole relay switches available
