Controls RTR-E Range : Two ranges: •Electromechanical on/off control based on air temperature •Electromechanical on/off control based on water temperature Wall-mount version to be installed by fitter. Use : CIAT's RTR-E on/off controllers are designed to control system-powered air-conditioning terminal units (fan coil units, UTA, cassettes, etc.) in 2-tube applications (air temperaturebased control) and 2-tube/2-wire or 4-tube applications (water temperature-based control) using recirculated air. Not only does it combine the economic benefits of installing and operating a central boiler and chiller plant, it also allows individual temperature control in all rooms. Description : Depending on model selected: •On/Off button •Manual fan speed selector (three speeds) •Manual summer/winter toggle switch •Terminals available with temperature adjustment dial
