Electromechanical fan coil thermostats RAB... very versatile stylish design high quality quick and easy installation Fan coil thermostats RAB... The room thermostats of the RAB... range from Siemens are especially designed for heating and cooling with fan coil units to maintain the selected room temperature. The thermostats are twoposition controllers with a twowire connection and acquire the room temperature with the help of a gas expansion diaphragm. The required room temperature is selected with the on the front of the unit. The fan speed is selected via a threeposition switch, and is also located on the front. The fan may continuously run at the selected speed or only when an output is activated. The Modern Solution RCC... Electronic fan coil thermostats RCC... LED s for operating mode indication auxiliary input (e.g. key card contact) automatic heating / cooling changeover asset protection (humidity damage prevention) Fan coil thermostats RCC... RCC Thermostats are used for heating, cooling or both heating & cooling with automatic changeover. They offer modern, microprocessorcontrolled room temperature control for fan coil applications. The RCC family members combine easiest operation with the highest flexibility. This, and the nice design, makes them especially suitable for hotel rooms. The required room temperature is selected via the on the front of the thermostat. A temperature sensor (internal or remote) senses the actual room temperature and maintains the set value by controlling the heating/cooling valves. An On/Off or 3point or even a precise analogue output signal is available. Automatic changeover from heating to cooling and vice versa in a 2pipe system is possible via a cable temperature sensor. The fan speed can be selected via a threeposition switch, also located on the front. LED s at the front indicate whether the controller is heating or cooling and if the fan is running. An optional remote temperature sensor allows control according to the return air temperature. Economy mode is commanded by an auxiliary contact (window contact, presence sensor, and key card or keyboard switch) can help to save energy. The Advanced Solution RDF...

RDF Thermostats are used for heating, cooling or both heating & cooling with automatic changeover. A version with manual changeover is also available. They offer modern, microprocessorcontrolled room temperature control for fan coil application. The RDF family members combine easiest operation, highest flexibility with a digital display. This, and the nice design, makes them especially suitable for offices and also for hotel rooms where a display is required. The required room temperature is selected via push buttons on the front of the thermostat. A temperature sensor (internal or remote) senses the actual room temperature and maintains the set value by controlling the heating/cooling valves. An On/Off or 3point or even a precise analogue output signal is available. Automatic changeover from heating to cooling and vice versa in a 2pipe system is possible via a cable temperature sensor. The fan speed can be selected via a switch, also located on the front, variants with automatic fan speed control are also available. The humidity damage prevention function works in conjunction with a key card reader and is especially designed for hotels in a warm and humid climate (asset protection). An optional remote temperature sensor allows control according to the return air temperature. 1
