ACL Ref. No. 0492 On/off operation of one or anumber of fans in relation to the room’s air quality. Operation Electronic air quality sensor tocontrol:–1 ph. fans up to max. 1 Amp. –3 ph. fans via contactor The unit has an integrated sensor which reacts on oxidable gases and pollutants like carbon monoxide, alcohol,formaldehydes,methane, tabacco etc. Designed to control ventilation ofpublic buildings like conference rooms, restaurants, shops, domestic rooms etc. Features The unit switches the fan on ifthe set pollution level is exceeded or if the concentration rises quickly. Adjustable (from outside)overrun timer after sensor hasswitched off. Indicator lamp show automaticor manual operation and operation and overrun time. Operation and on/off switch onfront plate.

Function Installation The air flow speed sensor (connected to controller) registers the air flow and compares it with the preset rate value. That can be set on the front of the unit (in the range from1 – 9 m/s). Relay contacts if the set valueis reached or exceeded. Thisfunction can be inverted on the bottom of the unit.

controller The fan speed is controlled stepless from 0 – 100 % in relation to temperature difference between the two remote sensors and the setrate value. EDTW Ref. No. 1613 Operation and advantages Electronical, stepless differentialtemperature controller forconnection of electronically speed controllable –ceiling fans and all 1 ph. fans. Two sensors with a flying lead(1 x 10 m for installation beneaththe ceiling; 1 x 2 m for installation above the floor). For continuous speed control tothe temperature difference. On/off (with function control) If the temperature differencerises, the fan speed increasesproportionally and slows downfor falling temperature. Automatic or manual operation. Designed for use in combinationwith ceiling fans or fans whichmove room air towards the floorto save heating energy. The unit optimises the differencebetween floor and ceiling temp. Reversing of air flow. Proportional range. Casing Summer operation:as manual speed controller.Depending on the fan type, motorhumming might be caused. Air flow sensor with mountingrosette for in-duct installation withcable, that is to be connected tothe controller. Impact resistant white polymer casing for flush or surface installation. Proportional range can be adjusted stepless from 1 … 10 K. 289
