EnOcean functions#
EnOcean is a wireless transmission protocol which uses the 868 MHz frequency to communicate with different devices. To enable wireless communication, an EnOcean module (TCM-320) is attached to the multi24. The modified multi24 plays the controllers part in the wireless network. This means that all the measurements and commands are transmitted to the multi24 and based on these readings, the multi24 controls different devices.
One multi24 can communicate with 128 different devices and the wireless signal transmission range is about 30 meter. Because of the amount of the devices and the transmission range, the control area is divided in to the smaller zones (zones 1 through to 9). To each zone, 1 room controller unit (RCU), 1 occupancy sensor, 1 illumination sensor, 5 valve actuators, 4 lights, 4 light switches (as many as there are lights) and 5 energy meters can be attributed.
Each EnOcean device, except lights, has a “learn” button which generates a special “learn message”. The multi24 reacts to that message and adds the device to the “known devices list” on the EnOcean chip. The multi24 is by default not in a learn mode, so the “learn mode” of the multi24 must be activated before sending the “learn messages” from the devices and sensors you wish to connect.
Equipment Profiles (EEP)#
Room Controller Units: A5-02-05, A5-04-01, A5-09-04, A5-10-01 and A5,-10-03. Examples of such devices: Thermokon SR04, Thermokon SR04P, Thermokon SR04PT, and Thermokon SR04-CO2.
Occupancy and light sensors: A5-08-01 Examples of such devices: Motion detector and light sensor (0-512 Lux).
Valve actuators: A5-20-01 PTM- & RCM- Modules: PTM-modules are known as pushbutton switches and its most common function is to communicate with lights. RCM-modules are modules that can only receive wireless telegrams and are most commonly attached to lights. The multi24 can imitate the PTM-module and communicate with an RCM-module.
Other Devices: It is possible to connect each and every EnOcean device to the multi24, but if the EEP-prodile is not listed above, a modification in the multi24 firmware is required. If you have a device that is not listed here, we will gladly add this in our next firmware release. Please contact your Fidelix representative if you have any questions.
