2.6 Environmental compatibility, disposal General notes This device was developed and manufactured with environmentally compatible materials and procedures complying with all relevant environmental standards. Note the following to dispose of the product following its useful life or in case of replacement: • Do not dispose of the device as part of standard household garbage, but as special waste from plastic and steel, ferrite-magnet components. This applies in particular to the PCB.
Please comply with these notes General regulations 3 Safety and EMC optimization 3.1 Notes on safety This section explains general and system-specific regulations for mains and operating voltages. It includes important information for your safety and the safety of the entire plant. Please comply with the following general regulations during engineering and execution: • • • • • Electrical and mains power ordinances for the given country. Other applicable, national regulations.
3.3 Notes on EMC optimization Setting up cable ducts When setting up cable ducts, separate strongly interfering cables from susceptible entities. Cable types • Interfering cables: Motor cables especially from motors supplied by inverters, energy-supplying cables. • Susceptible entities: Control cables, low voltage cables, interface cables, LAN cables, digital and analog signal cables. Separate cables • Both types of cables may be in the same cable duct, but in separate compartments.
4 Mounting and electrical installation 4.1 Mounting Comply with the following notes as well as the mounting instructions [2] to mount the room sensor. Ambient conditions Note the permissible ambient temperature and humidity. See data sheet [1] for environmental conditions. Mounting location Sensor mounted on interior wall of room to be conditioned: • • • • • • • At ca. 1.5 m height in the room and at least 50 cm from the next wall. Not on outside walls. Not in niches or behind curtains.
Connection diagram Maximum line length for universal temperature sensors and binary inputs: 10 m Seal the end of the installation conduit to prevent false measurements due to air drafts. Comply with the various regulations on separating various voltage levels when mounting the temperature sensor (with safety extra-low voltage protection) alongside the recessed conduit boxes connected to the low-voltage power.
Prerequisites 5 Functionality / Use 5.1 Basics 5.1.1 System environment For engineering and commissioning, sound knowledge of KNX networks as well as sufficient knowledge of working with ETS, ACS790, or ABT depending on system environment is a prerequisite. System environments and associated tools: System/Network environment Engineering and commissioning tool(s) KNX PL-Link ABT, SSA KNX LTE-Mode Synco ACS790 KNX S-Mode ETS • For ACS: An interface converter, e.g.
5.3 Functions The room sensor allows for measuring the room temperature, relative humidity, and CO2 concentration in the room. An additional, passive temperature sensor can be connected to measure another temperature. The binary inputs of the room sensor detect the status of up to two connectable, potential-free contacts. As a result, up to four measured values and two states can be transmitted to other members of the building automation and control system via KNX bus.
The integrated room humidity controller and room air quality controller can be used for ventilation control. Both controllers receive up to three switching point values, one blocking/release object, or a switching signal (e.g. motion detector) via the bus. When the respective switching point is exceeded, up to three control signals and one quasi-continuous signal to control the ventilation actuators are transmitted to other bus members. In addition, a signal with the max.
