Overview
The LCR Touch is a room operating unit with a touch surface and a 64 x 41 mm backlit LCD. It has a built in temperature sensor, with humidity as an option, and connects to an RS485 Modbus RTU network. It also has three inputs. From the panel the user adjusts the setpoint, fan stage, lighting (on, off, dim) and blinds, and sees status displays and an ECO mode. Typical places are schools, offices, hotels and cinemas. The inputs take a change-over sensor, floating contacts, a window contact and a presence or key card input.
