Assign only transmitters, the range of which needs to be extended. Any unnecessary assigning (learning) of transmitters may lead to data
collision and the Duty Cycle is being reached faster.
If assigning several transmitters one after the other, the increased radio traffic of the different transmitters in installation mode may be causal for
the reaching of a Duty Cycle (see section 8.).
After plugging it into a socket and pressing the learn key the device optimises the radio link for approx. 15 seconds. The repeater repeats no
telegrams during this optimisation cycle.
7. Cancelling of learned radio transmitters from the MRCOA-014.201 (deletion of radio links)
To cancel a learned radio transmitter from the Repeater, proceed as follows: Press the learn key at the corresponding transmitter and keep it depressed
until, after approx. 10 seconds, the indicator lamp stops blinking red and starts lighting constantly red. If the indicator lamp at the radio transmitter lights
constantly red, shortly depress the learn key at the Repeater in addition.
After the transmitter has been cancelled, the repeater automatically returns to normal operation. If the last transmitter has been cancelled, a lamp at the
repeater lights constantly red to indicate this.
7.1 Cancelling of all learned room temperature sensors from the MRCOA-014-201 (erasure of the entire channel data from the memory)
To cancel all learned transmitters at the repeater, the key at the repeater needs to be pressed permanently until the lamp, after approx. 3 seconds,
changes from blinking red to blinking green and finally lights constantly red. The indicator light at the repeater lights continuously to indicate that all
learned transmitters have been cancelled successfully.
8. Duty Cycle
In the frequency band used, the maximum transmission time of each device is 1% per hour (equivalent to 36 seconds per hour).
In individual cases, e.g. by frequently triggered learning processes, it may happen that the duty cycle is reached. The indicator lamp at the repeater
lights alternately red/green to indicate this. When the maximum transmission time is reached, the repeater ceases to forward radio telegrams (for a
maximum of 1 hour). No other radio transmitters can be learned (assigned) within this time.
9. Luminous indications at the radio repeater
Indicator lamp off:
Operation in normal mode. Prerequisite: The repeater has been plugged into a socket providing a 230V
power supply (see section 3.).
Continuously green:
The data of all assigned radio room temperature sensors have been deleted.
Constantly green
(every 3 min. for approx 3 seconds):
A radio link loss between the repeater and at least one transmitter occurred during the last 24 hours.
Blinking green:
Manual link test with one transmitter
– radio connection OK (see section 6.).
Blinking red:
Learn mode (see section 6.).
Blinking permanently red:
Loss of the radio link between repeater and at least one transmitter or no transmitter
assigned (learned) or all transmitters cancelled again (see section 7.)
Green/red alternately:
Duty Cycle limitation reached. The repetition of telegrams was stopped.
Green/red alternately
(for approx. 3 seconds):
An attempt was made to assign more than 16 transmitters.
