Thermostat-Controlled Socket
Operating Instructions

1. GENERAL DESCRIPTION OF THE SOCKET
The COMPUTHERM Q1RX socket has been developed for
thermostats COMPUTHERM Q3RF, Q5RF, Q7RF and Q8RF,
and can be used in addition to/instead of their receiver units. The
device is able to control boilers or any other electrical devices
operating on 230 V (e.g. fan heaters, pumps, zone valves, etc.).
Easy installation and operation, no assembly required. In response
to the ON command of COMPUTHERM Q3RF, Q5RF, Q7RF and
Q8RF wireless thermostats, a supply voltage of 230 V appears
on the output socket of device Q1RX connected to the network,
while the OFF command disconnects the device from the network.
If more than one COMPUTHERM thermostat has been paired to
the Q1RX socket, 230 V will be displayed on the output if any

4
thermostat sends an ON signal and the output will only turn o󰀨 if
all thermostats send OFF signal to the socket.
2. PUTTING THE SOCKET INTO OPERATION
It is advisable to install the COMPUTHERM Q1RX socket near the
device to be controlled, in a place protected from moisture, dust,
chemicals and heat. When choosing the location of the socket you
should remember that bulky metal objects (e.g. a boiler, bu󰀨er tank,
etc.) and metal building structures may have an adverse e󰀨ect on
propagation of radio waves. If it is possible, in order to ensure trouble-
free RF connection, we recommend that you install the receiving unit
at a height of 1.5 to 2 m and at a distance of 1 to 2 m from the boiler
or other bulky metal constructions. We recommend that you check
reliability of RF connection at the place selected before installing the
receiving unit.

ATTENTION! Do not install the socket under the housing of the
boiler or near hot pipes because it may damage the parts of the
device or compromise wireless (radio-frequency) connection.
WARNING! Modifying the socket can cause electric shock or
product failure.
Plug the COMPUTHERM Q1RX device into a power socket near the
location of the device to be controlled. A few seconds after the LED
lights of the device ash once, the device becomes ready for operation.
After this, you can start tuning the socket and the thermostat(s) (or the
socket, the receiver of the thermostat and the thermostat) together.

3. TUNING THE SOCKET AND THE
THERMOSTAT(S)TOGETHER
ATTENTION!If you wish to use the COMPUTHERM Q1RX socket
in addition to the receiver unit of the thermostat, then the socket,
the receiver of the thermostat and the thermostat should be tuned
together at the same time, so that they can operate simultaneously.
ATTENTION! The socket can be paired with up to 12 separate
COMPUTHERM wireless thermostats at the same time. If you do not
want a particular thermostat to control the socket, pair the thermostat
with another COMPUTHERM wireless device or reset the socket.
Press the “ON/OFF” button of the socket (for approximately 10
seconds) until the green LED light starts ashing. If you also wish to
use the receiver unit of the Q3RF, Q5RF, Q7RF or Q8RF thermostat,

7
then start the tuning process on that receiver unit too, as described in
its manual, so that its green LED light (or red LED light in case of the
receiver of the Q5RF or Q8RF thermostat) starts ashing. After this,
tune the devices together according to the manual of the thermostat.
If the LED lights stop ashing, then the devices are tuned together.
If you want to pair more than 1 thermostat with the socket, then
repeat the previous steps with the other thermostats too. If you have
reached the maximum (12) synchronizable product limit, then the
red and green LEDs on the product will ash alternately 3 times after
pressing the „ON/OFF” button for 10 seconds. In this case, to pair a
new thermostat, the socket must be reset by pressing the „ON/OFF”
and „Manual” buttons together for 10 seconds. Both LEDs will then
light up for 2 seconds to indicate that the socket has been reset and
synchronization of the new thermostats can begin.

Attention! When reset, both the O󰀨 and On delays return to the o󰀨
state.
4. DELAY OF THE OUTPUT
When designing heating zones - in order to protect the pumps - it is
advisable to keep at least one heating circuit that is not closed by
a zone valve (e.g. bathroom circuit). If this is not made, in order to
prevent the heating system from an event in which all heating circuits
are closed but a pump is switched on, the socket has two types of
delay function.
Turn on delay
In turned on state, if the output of the socket is switched o󰀨, in order
to open the valve(s) of the given heating circuit before starting the
pump, the socket output switches on after a delay of 4 minutes from

9
the switch-on signal of the rst thermostat. During this time, the valves
open and then the pump connected to the socket starts. The delay
is especially recommended if the zone valves are opened/closed by
slow-acting electrothermal actuators, because their opening/closing
time is approx. 4 min. If the socket output is already switched on,
the Turn on delay function will not be activated when the additional
thermostats switch on.
The active state of the Turn on delay function is indicated by the
green LED ashing with 3-second intervals.
If the „MANUAL” button is pressed while the Turn on delay is active
(green LED ashes with 3-second intervals), the LED stops ashing
and indicates the current operating mode (Automatic/Manual).
Press the „MANUAL” button again to change the working mode.
After 10 seconds, the green LED continues to ash with 3-second
intervals until the delay stops.

10
Turn o󰀨 delay
In the activated state, if the output of the socket is switched on, in
order to keep the valve(s) open of the given heating circuit during the
pump circulation, the output of the socket switches o󰀨 after a delay of
6 minutes from the switch-o󰀨 signal of the last thermostat. The delay
is especially recommended if the zone valves are opened/closed by
quick-acting motorized actuators, as their opening/closing time is only
a few seconds. Activating the function in this case ensures that the
heating circuits are opened during the circulation of the pump and thus
protects the pump from overload. The function is only activated if the
last thermostat sends a switch-o󰀨 signal to the socket.
The active status of the Turn o󰀨 delay function is indicated by the red
LED ashing with 3-second intervals while the red LED is still lit.
