Programming

• AUX 4: Four auxiliary switches to control watering, supplemental lighting, etc.

• CAC: Central alarm contacts for connection to building alarm system

• ADIAL: Automatic telephone dialer to notify users of chamber alarm

• ACP: Additional controlled parameter such as root zone, lamp loft, etc.

Lighting Options

• EL: End lamps to reduce light fall-off at the ends of the lamp canopy. (60 Hz only)

• M10: Fluorescent/incandescent lighting provides up to 1400 micromoles

• HID: High intensity discharge lighting providing a light intensity of up to 1200 micromoles

• LMM: Controller display of light intensity in micromoles

Temperature Options

• LT: Low temperature operation range to meet your requirements

• DE: The DE option allows continuous operation at -5°C with all lights ON and -10°C with all lights OFF

Carbon Dioxide Additive Control

• C02: CO2 control. Range: Resultant to 2,990 ppm.

Humidity Options
(based on +21°C and 50% RH ambient conditions)

• SNH: Range: Up to 90% RH lights OFF and 85% RH lights ON, limited by a +25°C dew point. Additive humidity through use of spray nozzles. Control: ±3% RH

• CPSNH: Compact pump and reservoir for spray nozzles. Order this option with SNH if the minimum 60 psi (4.2 bar) water pressure is not available

• RES: Pressure reservoir downstream of chambers. All downstream chambers must be fed from CPSNH.

• BDH: Bypass Dehumidification limited by a +7°C dew point
