Day & Night CO2, Relative Humidity & Temperature Smart Control - iGS-220: J

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

iGS Day & Night Humidity Control With Display

iGS Day & Night Humidity Control With Display The iGS-030 relative humidity controller will operate your humidifying or dehumidifying equipment in accordance to user day and night set points. The ambient relative humidity is displayed on the luminous bar graph. The precision RH sensor (3%) can be calibrated and the differential of operation is adjustable. This controller is also available with a remote (10 feet) sensor (iGS-030R). Details IGS030 Day & Night Humidity Control With Display IGS030R Day & Night

USDT 2004B Basic Solar Differential Controller - digital display, adjustable trigger from 4.1°F to 99°F, 115vac

A basic temperature differential controller for solar water heating systems, this microprocessor based temperature controller regulates solar water heating systems and any other heating systems such as: storage tank charging and boiler activation systems. The USDT 2004B monitors and displays supply and return temperatures. When the supply temperature exceeds the return temperature by a programmable temperature difference (?T), an internal relay powers a 0.25 HP pump or an auxiliary relay. To avoid
