Radio Frequency Controls Single-room control in the form of either thermal or electrothermal control has been state of the art in new buildings for years. In many existing buildings, however, there is increasing need to retrofit these systems for added comfort and energy savings. Radiators can be economically retrofitted with radiator thermostats. In the past, it has always been difficult to retrofit hot water floor heating systems that are not equipped with thermostats in their respective rooms. Today, these room units are still controlled with manually set flow controllers in central manifold...

General Information on Radio Frequency Systems The INSTAT 868 radio frequency controller range offers ideal wireless transmitters and receivers for any type of application. For each heating zone, either the INSTAT 868-r1 radio frequency transmitter with analogue temperature setting or the INSTAT 868-r/rd digital clock thermostat is used, and both can be combined with the INSTAT 868-a1A 1-channel receiver. For several heating circuits, 4- or 6-channel INSTAT 868-a4/a6 receivers are used, which can be expanded and combined with each other as desired. For mobile electric heaters, such as wall-mounted...

Radio Frequency Transmitter – With Analogue Temperature Setting Radio frequency room temperature controller (transmitter) Battery-powered, electronic room temperature controller with rotary knob for setpoint adjustment. The room temperature controller is placed freely – no wiring needed – in the room (wall mounting), for wireless radio transmission of the actuating values to a receiver. The INSTAT 868-r1 selector switch allows the user to manually influence timer operation (master/slave), comfort, night temperature and off for each control zone. General Technical Data Type Adjustable temperature Energy...

RF Repeater - INSTAT 868-rep Series RF Repeater for INSTAT 868 r… The INSTAT 868-rep and the INSTAT 868-repS are amplifiers of RF signals. These Repeaters repeat the received signals of the INSTAT 868-r transmitter automatically. They increase the distance of radio transmission between INSTAT 868-r... RF-thermostats and INSTAT 868-a... receivers and they enable an improvement of the received signal qualitiy of a receiver. 2 repeaters can be used in sequence and they insert themselves automatically into already existing radio links of the INSTAT 868 system. Only one Repeater is necessary for many...
