AMR-OP75RHR(C) – room control unit
AMR-OP75RHR(C) is a universal room control unit for control systems or controllers, designed for comfortable control of common functions in rooms such as:
- Temperature control
- Ventilation control
- Shading control
- Lighting control.
The basic control element is a high-quality, high-resolution colour graphic display with a touchscreen. The user interface is intuitive yet versatile enough for a wide variety of functions. The unit is delivered with the application already loaded.
The main features include:
– TFT colour touch screen with 320×480 px resolution
– Backlit display with ambient control
– RS485 interface w/o galvanic isolation
– MODBUS RTU communication protocol
– 24 V DC power supply
– Wall mounting or mounting box type KU 68
– Control of desired room temperature, ventilation, shading, lighting and predefined scenes
– Possibility of signalling the exceedance of measured values
– User selection of light or dark display mode of the application
– Wide configuration options, support for configuration setup via AppConfig
There are two basic unit variants:
AMR-OP75RHR – measures temperature, humidity, universal RTD/NTC input, relay output
AMR-OP75RHRC – additionally measures CO2 concentration (with automatic recalibration) and allows audible signalization of exceeding CO2 limits.
The AMR-OP75RHR(C) can replace several room controls and switches with a single device, contributing to interior aesthetics.
