REMOTE ACTUATOR MODEL RX7-5A
Read all the instructions carefully
V3IS00647-010
Mod. RX7-5A
The remote actuator RX7-5A is an electronic independently mounted automatic control for
heating and air conditioning applications, designed for comunications in the range of Vemer
thermostat and programmable thermostat via radiofrequency or via bus.
It provides a type 1B actions and it is designed for household and similar use with overvoltage
category III and pollution level 2 (EN 60730-1).
SAFETY WARNINGS
During product installation and operation, the following safety instructions should be
respected:
1) The instrument should be installed by qualied personnel
2) Before touching the terminals, make sure there is no power supply to the electric wires
3) Do not power or connect the instrument if any part of it is damaged
4) Follow the connection diagrams descripted on this manual and over the instrument
5) The electrical system of the building in which the instrument is to be installed should have a
switch and a protective device against over-currents.
6) The instrument must be installed and activated in compliance with current electric systems
standards
7) After installation, inaccessibility to the connection terminals without appropriate tools must
be granted.
Code Model Description
VE443800 RX7-5A Remote actuator

• Storage temperature: -10°C ÷ 65°C
• Operating humidity: 20 ÷ 90% non condensing
• Enclosure: 4 module DIN
• Protection degree: IP20 (IP40 when correctly installed in an electrical panel)
• Insulation: reinforced among frontal and all other terminals
OPERATION
GREEN LED: operation function (power supply)
RED LEDS: relay status (output 1 - 6)
YELLOW LED: relay status (output 7)
SET KEY for programmation and reset channel
TRIMMER to set the relay 7 switching delay
Network example
OPERATION
• In starting phase, the red leds and yellow led ashes twice for some seconds (switching on-
sequence).
• At the end of the switching on-sequence, the green LED signal normal device operation and
the red LEDs relay status (light on = relay ON).
If at least one of the zone valve output (relay 1 ... relay 6) is turn on, automatically is
also activated the pump output (relay 7), with a delay that can be set from 3 seconds to 5
minutes by trimmer on the front of the instrument.
• The remote control (relay commutation ON/OFF) request from thermostats and
programmable thermostats take place only after channel setting-up.
• The radio connection break down for more than 15 minutes between the transmitter
and the receiver disconnects the relay/relays and the red LED/LEDs lightened. Restore of
operations is automatic.
Channel setting-up
– During normal operation, press the SET key-button for almost three seconds to enter in
modality-conguration. Green LED switch-off, red LED ash. Press the SET key-button
to select the output relay.
– The instrument keep on modality-conguration for a maximum of 60 seconds within
the actuator should receive a string conguration (see thermostats or programmable
thermostats instructions for string start-up modality).
– On receipt of string, channel is setted-up and the actuator is on standard functioning.
– For re-setting up, repeating the procedure.
• To reset channel setting-up, plug into conguration modality with SET button, then push
the same one for three seconds and wait for green led switching on.
SERIAL OUTPUT
RX7-5A features an insulated serial output RS 485 for communication. It is possible to
connect up to 31 instruments up to a maximum distance of 40 m.
Note: It is possible to connect a remote actuator with different programmable
thermostats Athena. In this case it is necessary to congure different zones
for each Athena. Exemple: 2 Athena are connected with a remote actuator: if
Z1 is selected in the rst Athena, then Z2, Z3 or Z4 must be selected in the
second Athena.
STANDARDS REFERENCE
Conformity to the EU directives:
2006/95/EC (Low Voltage)
2004/108/EC (Electromagnetic Compatibility)
is declared with reference to the following harmonized standard:
EN 60730-1
EN 301 489-1/3 and EN 300 220-1/2
- Living room probe: built into Athena programmable thermostat
- Bedroom probe: remote, connection to Athena via bus 485
- Bathroom probe: built into Klio
- Entrance probe: remote, connection to Athena via bus 485
- Kitchen probe: built into Mithos RF
The air-conditioning equipment is controlled by means of a remote actuator (RX7-5A) via RF
and/or 485 bus.
