A GENERAL DESCRIPTION OF THE
RECEIVING UNIT
Room thermostat receiver
COMPUTHERM
Q7RF (RX)
is suitable to operate together with wireless room
thermostats
COMPUTHERM
Q3RF,
COMPUTHERM
Q5RF,
COMPUTHERM
Q7RF and
COMPUTHERM
Q8RF.
The
COMPUTHERM
Q7RF (RX) type switched-mode
room thermostat receiver controlled by a wireless
COMPUTHERM
room thermostat is suitable to regulate the
overwhelming majority of boilers and air conditioners.
It can easily be connected to any gas boiler or air
conditioning device that has a double wire connector
for a room thermostat, regardless of whether it has a
24 V or 230 V control circuit. The receiving unit controls
the connected gas boiler or another electric device
according to signals coming from the room thermostat
switch.
If you want to make your gas convector controllable
with a room thermostat using
COMPUTHERM
KonvekPRO
- 3 -
and a
COMPUTHERM
wireless room thermostat and
you wish to control several gas heaters with a single
room thermostat, you can accomplish this task by
means of a
COMPUTHERM
Q7RF (RX) receiver unit.
A single
COMPUTHERM
wireless room thermostat can
be synchronized with several
COMPUTHERM
Q7RF
(RX) receiver units at the same time, and this make
simultaneous control of several gas convectors feasible
(for more details please refer to Chapter 1).
1. INSTALLATION AND CONNECTION
OF THE RECEIVER UNIT
The
COMPUTHERM
Q7RF (TX) receiver unit should be
mounted on the wall in a place protected against mois-
ture and heat, in the vicinity of the boiler. When choosing
the location of the receiving unit you should remember
that bulky metal objects (e.g. a boiler, buer tank, etc.)
and metal building structures may have an adverse ef-
fect on propagation of radio waves. If it is possible, in
order to ensure trouble-free RF connection, we recom-
- 4 -
mend 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 oth-
er 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 receiver unit 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. To avoid
electric shock, entrust a specialist with connecting
the receiver unit to the boiler!
The device must be installed and connected by a
qualied professional.
WARNING! Modifying the thermostat can cause
electric shock or product failure.
Unscrew the two screws at the bottom of the receiver
unit without removing them. Following this, remove the
front panel of the receiver unit then x the back panel to
the wall in the vicinity of the boiler with the screws pro-
- 5 -
vided. Remove the protective carton from the contacts to
ensure perfect contact.
The marks of the connections are pressed into the plas-
tic above the connection points: N, L, 1, 2 and 3.
230 V mains voltage should be supplied to the receiver
unit. This provides the power supply for the device, but
this voltage does not appear on the terminals 1and 2.
We propose to connect the neutral wire of the network to
point N, while the phase conductor to point L. We recom-
mend using a fork type connection including a switch for
mains connection. Please de-energize the device when
heating is continuously not needed (e.g. summer).
The receiver unit controls the boiler or air conditioner
through a potential-free alternating relay whose con-
nection points are: 1 (NO), 2 (COM) and 3 (NC). Con-
nect the two connection points of the heating or cooling
equipment to be controlled to terminals No. 1 (NO) and
No. 2 (COM), i.e. to the normally open terminals of the
relay as shown in the gure.

If you would like to operate an old boiler or any other de-
vice that has no connection points for thermostats, then
the No. 1(NO) and No. 2(COM) connection points of
the thermostat should be connected to the mains cable
of the device, similarly as a switch would be connected.

If you want to control several gas convectors by using a
single room thermostat then you need a
COMPUTHERM
wireless room thermostat (it already comprises a receiving
unit), and as many
COMPUTHERM
KonvekPRO gas convector
controllers as the number of gas convectors to be controlled
and one less
COMPUTHERM
Q7RF (RX) supplementary
receiving units. The gure below shows control of two gas
convectors with a single wireless room thermostat. In case
of more than two gas convectors a similar arrangement
can be implemented by additional receiving units and
COMPUTHERM
KonvekPRO gas convector controllers.

When you are able to establish wired connection between
the gas convectors, you can also set up the system by
using fewer
COMPUTHERM
Q7RF (RX) receiving units as
shown in the gure below.

ATTENTION! Always consider the loadability of the re-
ceiver unit and follow the manufacturer’s instructions
of the heating or cooling equipment. The device must
be installed and connected by a qualied professional!
The voltage appearing at terminals No. 1 (NO) and No.
2 (COM) depends only on the system being controlled,
therefore the dimensions of the wire are determined by
the type of the device to be controlled.
The length of the wire is of no signicance, the receiver
unit may be installed either near the boiler or far away
from it, but do not install it under the housing of the
boiler.
If the distance between the transmitter and receiver units
is too large due to local circumstances and it makes the
wireless (radio-frequency) connection unreliable, install
the receiver unit nearer to the place of thermostat or use
a
COMPUTHERM
Q2RF signal repeater to increase the
communication distance.
