RDE-MZ6 S55770-T285 Wireless multizone receiver AC 230 V
Ordering
When ordering, please indicate product No. / stock number and description.
For example:
Standalone RF transmitters, valve actuators and manifolds must be ordered
separately.
Optional: External antenna for multizone receiver RDE-MZ6
In case of weak connectivity of the RF signal between wireless thermostat
(RDD100.. / RDE100..) and the multizone receiver (RDE-MZ6) or special
installation inside a metal enclosure, the user has the option to mount an external
antenna. Remove the existing white antenna by turning off the antenna screw head
and screw on the black external antenna. External antenna has to be placed on a
convenient point and open space (it has a magnetic base). It is recommended to
pair the units once again if necessary, please refer to the Commissioning Notes
below.

Mechanical design
The RDE-MZ6 multizone receiver consists of a plastic housing which
accommodates the electronics and features a built-in snap for direct mounting on
DIN 35 rails (as per EN 50022).
1) Channel state LEDs for zones
1 to 6. Zone 6 can be
reconfigured for pump or
boiler release
2) LEARN button for zones 1 to 6
(or override)
3) RESET button for all zones
Mounting and installation notes
DIN rail installation ∂Place the receiver on the DIN rail from the top
∂Gently push the receiver downward until it snaps onto the rail
Mounting ∂Install the receiver close to the controlled unit, if possible
∂Choose the location to ensure largely interference-free reception. When
mounting the receiver, observe the following:
,Do not mount in a control panel
,Do not mount on metallic surfaces
,Do not mount near electrical cables and equipment like PCs, TVs,
microwaves, etc.
,Do not mount near large metallic structures or constructional elements with
fine metal meshes such as special glass or special concrete
,Use of external antenna if necessary
Wiring See Mounting Instructions CB1M1428xx enclosed with the multizone receiver.
∂Make sure the multizone receiver is not connected to power during wiring
∂Ensure that wiring, fusing and earthing comply with local regulations
∂Correctly size the cables to the multizone receiver and the valves / manifold /
pump
∂Use only valve actuators rated for AC 24… 230 V
∂If the receiver cannot accommodate all cables, power must be fed to the
system via an external terminal block
Warning!
No internal line protection for supply lines to external consumers.
Risk of fire and injury due to short-circuits!
∂Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device.
∂The AC 230 V mains supply line must have a circuit breaker with a rated
current of no more than 10 A
∂Disconnect from power supply before removing the multizone receiver from the
DIN rail

Commissioning notes
For the pairing process between transmitter and receiver, refer to Operating
Instructions CB1B1428en, together with CB1B1431en for the RDD100.1RF, or
CB1B1432en for the RDE100.1RF.
The table below describes the behavior of the RDE-MZ6:
State of receiver State of LED
Power up (or reset) All 6 red and green LEDs flash alternately for 5
seconds and then extinguish.
Note: If the receiver zone was programmed before,
it will immediately change to constantly red.
Learning mode
Successful learning mode
The respective zone’s red and green LEDs flash
alternately.
The respective green LED will flash for 10 minutes
if learning was successful.
Signal ok and output status
change
For boiler or pump release
The respective zone’s green LED is constantly lit. If
the output state changes, the green LED will flash
for 3 seconds and then changes back to constantly
green.
Zone 6:
The green LED is lit when the relay is energized. It
extinguished when any other relay is deenergized.
Fails to receive wireless data If the respective zone of the RDE-MZ6 fails to
receive wireless data, the red LED will start to flash
after 125 minutes.
If RDE-MZ6 signal is recovered, it will return to the
previous LED state.
The specific zone has no ID The respective LED extinguishes.
Zone 6 of the receiver can be reconfigured for pump or boiler release. In that case,
the user is required to set the DIP switch inside the receiver housing to 1 (ON) (for
details, refer to Mounting Instructions CB1M1428xx).
The multizone receiver provides an override function (testing, emergency
operation). It allows the installer to override the relay of each zone to be
permanently energized, regardless of the wireless data received.
To activate the override function, press and hold the zone button for at least 10
seconds and release. The LED is constantly green and off once every 5 seconds,
indicating that the override function is enabled.
To disable the override function, press the zone button once.
Maintenance note
The multizone receiver is maintenance-free.
Disposal
The device is considered an electronic device for disposal in terms of the
European Directive 2012/19/EU and may not be disposed of as domestic
garbage.
∂Dispose of the device through channels provided for this purpose.
∂Comply with all local and currently applicable laws and regulations.
