Description     Igs-220 Day & Night CO2, RH, TEMP Smart Control This electronic module performs control over CO2 enrichment or venting, heating or cooling and humidification or dehumidification equipment to maintain user CO2, temperature and relative humidity day and night setpoints. The control unit logs the last 24hr minimum, maximum and average values for the user to scan through. A dry contact triggers when temperature or relative humidity values are not within user-specified limits or when a power outage is at hand. Different operation modes can be set to comply with diverse set-ups. Each output can be set to operate during the day only, the night only or day and night. 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 24hrs minimum, maximum and average CO2 concentration, relative humidity and temperature values. Multiple operation modes are available and the differential of operation is adjustable. Optimize climate control and reduce energy bill : ·  Multiple configurations enable the user to prioritize CO2 control over temperature or relative humidity management or vice versa. Optional timers (5 and 10 minutes) can be set to maintain the output OFF after CO2 enrichment process has ended. Follow-up on your set-up performance : ·  The controller is constantly analyzing its performance and issues in the form of hint codes a report to the user. The percentage ratio of the ON time of each output is obtainable through the hint codes. The 24hr datalogger lets the user follow-up on the evolution of CO2 concentrations, relative humidity and temperature day and night. Be wary of your CO2 sensor precision : ·  After a full year of use the controller will display an error message which indicates to the user that a recalibration of the CO2 sensor is advised. Once the procedure is performed (10 minutes maximum) this message will disappear to reappear a year later. The controller also offer an altitude correction factor (up to 9500 feet). Be warned when RH or temperature values go array or during a power outage : ·  The controller will activate a dry-contact output when temperature or RH values go outside user limits or when a power outage has happened. This dry-contact output can be connected to a back-up system, an alarm system or an automatic dialer.
