FEATURES
TECHNICAL DATA
DESCRIPTION
● Rated supply voltage 230 V AC.
● Compatible with EXTA LIFE system control-
ler and transmitters.
● With 2 output channels (2 x potential-free
NO/NC switchable contacts).
● Two-way transmission with an indication of
each output status in the application.
● Programmable output status after supply
voltage loss.
● 2 programmable external inputs.
● For connecting monostable or bistable con-
nectors.
● 4 operating modes when working with trans-
mitters (activate/deactivate, bistable, mon-
ostable, time).
● 2 operating modes when working with con-
troller (activate/deactivate, time).
● Independently programmable time for radio
transmitters, external inputs and for control-
ler.
● Times assigned independently for each out-
put.
● Software can be updated remotely.
A ROM-22 modular radio receiver is the fi-
nal element of EXTA LIFE system which allows
individual control of any two devices/circuits.
Two relays with switch contacts (NO/NC) with
maximum rated load 10A as outputs. This ena-
bles the user to control low voltage circuits (e.g.
12/24 VAC/DC) and high voltage circuits (230
VAC). The receiver is also good for remote ac-
tuation of other devices. You can also use it for
feeding control signals. The ROM-22 receiver is
also suitable for controlling solenoids in heating
systems. Thanks to bidirectional communica-
tion between the receiver and controller, you
can view each receiver channel’s status at any
particular time on a mobile app. Also, the bidi-
rectional communication enables the operator
to change the specific parameters of the receiv-
er and add receivers remotely (i.e. without the
actual access to the receiver). Frame encryp-
tion algorithm ensures control safety. A receiver
installed outside a controller may be controlled
in parallel using the EXTA LIFE system’s trans-
mitters. You can register more transmitters with
a receiver to enable independent control from
several locations. Configurable cable inputs in-
crease control functionalities. The receiver has
a built-in remote software update from a con-
troller. The product is designed for installing in
switch cabinets using a TH35 (DIN) bar. With
removable antenna to enable connecting an
external antenna.

*** Times are assigned independently to each channel of the receiver. The periods are programmed separately for
buttons operating in time mode, external inputs and for control from the app level.
