2-way touch sensor with temperature controller R.1 glass, polar white. 2-way touch sensor with temperature controller with all-round bevel, with rounded corners, without visible fastening elements, with four control surfaces, LED display with symbol representation to show operating mode, controller lock, room and outside temperature, time (timer required), with 2 additional display sensor surfaces, with a blue operating LED, with four white status LEDs. Flush-mounted installation, special program. Control element for room-specific and cross-room control of functions. For individual single-room temperature control, actuation by touching the glass plate (capacitive detection), flat design and high switching reliability by applying the conductor tracks directly to the glass plate, for installation in a 2-way installation box. For vertical installation, with disassembly tool, with integrated bus coupler, bus connection via connection terminal. Display menu scope for operation can be parameterized. For switching, touch, dimming, blinds, room temperature controller functions, value transmitter for dimming, position, brightness and temperature values 1 and 2 bytes, single and double surface operation can be parameterized, sensor surfaces can be locked via object, controller operating modes: comfort, standby, night and frost/heat protection mode. For heating and/or cooling operation with/without additional stage, control parameters for heating or cooling elements preset. For continuous (PI) or switching (2-point) control, temperature measurement via internal and/or external, connectable sensor with averaging, signaling objects for heating and cooling, with valve protection function, object for controller status, with key lock function.
