The iGS-220 CO2 relative humidity and temperature controller is the simplest and most complete solution to integrated climate management and CO2 enrichment or venting. The resulting climate can increase yields and quality of harvest while insuring CO2 and energy savings. The electronic module displays the actual values of the CO2, relative humidity and temperature sensors. The controller includes an internal fan to speed up the air sampling process thus yielding better climate control. The control unit can be positioned up to 6 feet away from the output box (a cable up to 50 feet can be used). The control unit logs the last 24 hrs minimum, maximum and average CO2 concentration, relative humidity and temperature values. Multiple operation modes are available and the differential of operation is adjustable.
