-7863A has 2 timer outputs for lighting, ventilation, air or fatigue. Timer 1 on/off period could have different temperatures and humidity, to day and night. It can be applied to control the climate for green houses, , etc.The heat pump (compressor) can save energy. In addition to simple heating R6/cooling R7 output control. Refrigeration only by compressor, driving by R6. Constant temperature control by compressor, conduction by R6, R7 and .Constant temperature control, cooling or heating; Humidification, dehumidification or constant humidity level controlTwo timer outputs; Warning about temperature or humidity levelReboot after the power supply returns; Compressor delay protection (if heated or cooled by compressor)Power supply: 100 ~ 240VAC, 50/60Hz.Output: @ 250Vac 3A, for the 7 outputs.To drive larger loads, use intermediate relay 10A ~ 40A, -XXAA or magnetic contactor.Input: one humidity sensor, provides a cable length of 2 .One temperature sensor, R10K @ 25 /B3470 @ 25/50 Humidity Sensor: If the humidity is less than 80% RH, select -SHr05J.If the humidity exceeds 80% relative humidity, select -SHr05P.Setting range: humidity 0~99%RH, temperature 0~65.Sensor accuracy: humidity +/- 3%(-SHr05J), temperature +/- 1% @ 25 .Control Resolution: Humidity 1%RH, Temperature 0.1.Working Environment: -10 ~ 45; less than or to 90% RH without Dew.Hole size: L 71 x W29 (mm).Protection level: IP65 (front panel only).Manual (copy and paste into the browser address to and download): http://.suzhoulily./pdf/-7863A_en_V2.0.pdfThe content of the pdf file can be translated using web translation.colour: blackMaterial: plasticPackage Contents:1 x temperaturehumidity controller1 x -SHr05JOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
