1.1 Product Compliance
1.2 Safety Informations
Care for the natural environment is of paramount importance to us.The awareness that we manufacture electronic devices obliges us
to dispose of used electronic components and devices safely.Therefore the company has received a registration number issued by the
ChiefInspector for Environmental Protection.The crossedoutsymbol the trashcan on the product means thatthe product must not be
disposed of with ordinary waste containers. Sorting waste for recycling helps to protect the environment. It is the user’s responsibility
to surrender used equipment to a designated collection point for recycling waste from electrical and electronic equipment.

The RT520RF room thermostat simply switches the heating system on and o as necessary. It works by sensing the air temperature, switching on the
heating when the air temperature falls below the thermostat setting, and switching it o once this set temperature has been reached.
Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the
heating system, for example, the size of boiler and radiators. Neither does the setting aect how quickly the room cools down.Turning a room thermostat
to a lower setting will result in the room being controlled at a lower temperature, and saves energy.
The heating system will not work if a time switch or programmer has switched it o.
The way to set and use your room thermostat is to nd the lowest temperature setting that you are comfortable with, and then leave it alone to do its
job. The best way to do this is to set the room thermostat to a low temperature – say 18⁰C – and then turn it up by one degree each day until you are
comfortable with the temperature.
You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will usually be only one room thermostat to control the whole house. But you can have dierent
temperatures in individual rooms by installing thermostatic radiator valves (TRVs) on individual radiators. If you don’t have TRVs, you should choose a
temperature that is reasonable for the whole house. If you do haveTRVs, you can choose a slightly higher setting to make sure that even the coldest room
is comfortable, then prevent any overheating in other rooms by adjusting theTRVs.
Room thermostats need a free ow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric res,
televisions, wall or table lamps may prevent the thermostat from working properly.
Thermostat is compatibile with OpenTherm OT+ 4.0 version.
The OpenTherm protocol is an open standard communication protocol used in central heating systems for two-way communication between a central
heating boiler and a room thermostat.Thanks to the communication protocol, the boiler power is modulated, which can signicantly increase the energy
eciency of the heating system while maintaining the set temperature in the room. OpenTherm modulation, compared to standard communication (ON
/ OFF), occurs by setting the desired temperature of water from the boiler (boiler power), and not by its cyclical switching on and o.
PLEASE NOTE!
Make sure your gas combi boiler is compatible with OT + 4.0 communication protocol.
The list of compatible boilers is on the next page.
Product advantages:
• set is factory-paired and ready to work
• option to choose Hysteresis or built-inTPI algorithm for all types of heating
• works with time schedules
• service mode protected by a PIN code
• maximum / minimum temperature limitation
• can temporarily change the temperature (overwriting until the next program change)
• has unique transmission codes
• operates at 868 MHz - a stable and noise-resistant signal

2.4 Proper thermostat location
Please note:
The ideal position to thermostat mounting is about 1,5m under oor level far from heating or cooling sources. Thermostat can’t be
exposed to sunlight or any extreme conditions like for example draft.
Because of re and explosion risk there is not allowed to use thermostat in atmosphere of explosive gases and ammable liquids (eg coal dust). In case
if any of listed dangers occur you have to use additional protection measures – anti-dust and explosive gases (tight cover) or prevent their formation.
Furthermore, thermostat can’t be used in condensation of water vapor conditions and be exposed to water action.

3. RXRT520 receiver
3.1 Receiver’s switches description
The thermostat communicates wirelessly with the RXRT520 receiver. The receiver should be supplied with 230VAC, the maximum load of the receiver is
16A. Avoid installing the device in places directly exposed to water, moisture and air condensation. The RXRT520 receiver can operate in two dierent
modes - AUTO (automatic) and MANUAL (manual).To select a specic mode, use the buttons on the front of the receiver.
For the receiver to work with the thermostat, set the switches to the ON / AUTO position.

The status of the RXRT520 receiver is indicated by two LEDs.These are
LEDs with the following colors:
- red (upper one),
- green (lower one).
A detailed explanation of the meaning of the LEDs can be found in the table below:
MEANING
The red LED lights up
The receiver is connected to the 230V power supply and is paired with the thermostat.
The receiver can be thermostat-enabled if it is in automatic mode when the lower switch is in the AUTO position.
The receiver can be started manually when the lower switch is in the MANUAL position.
The red LED ashes
The receiver is in the pairing mode and is looking for a signal from the thermostat (then you must activate the
“PAIRING”option in the thermostat)
(or)
The receiver was paired but lost communication with the thermostat due to out of range or low battery in the
thermostat. The receiver starts ashing after one hour of time when it does not receive a signal from the thermostat.
The red diode is o The receiver is disconnected from the 230V power supply or the upper switch is in the OFF position.
The green diode lights up
In automatic mode, the receiver received a heating signal from the thermostat.
The receiver was started in manual mode (upper ON switch, lower MANUAL switch)
The green diode is o The receiver does not send a heating signal.

3.3 Wall mounting of the receiver
Wall mounting the receiver: drill two ø6 mm holes in the wall. Insert the plugs and, by putting the plate to the wall (included in the set), put the two
screws through the holes and then screw them in. Connect the necessary cables to the receiver. Next, hang the receiver on the board using the handles
designed in the receiver, marked in the picture below.
Loosen the screws with a scre-
wdriver just enough to tilt the
back housing.
Attach the back housing to the wall
(keeping the correct positioning of the
plastic„hinges”) using the marked holes
(see the picture above).
Put the receiver from above on the back
housing attached to the wall, according to
the position of the plastic„hinges”.
Tighten the screws from the
bottom of the back housing.
Tilt the receiver cover upwards
(according to the position of the
„hinge”).
Then, correctly connect the wires
included in the set with the
receiver (see„connection diagrams”
on page 11).

value.
Span is the temperature difference, between which thermostat operates and keeps
setpoint temperature. For example, if you set setpoint temperature to 20°C and if the
hysteresis is ± 0.5°C, heating will be turned on when the room temperature drops to
19.5°C and turned off when the room temperature reaches 20.5°C.

Using or , select the TPI type you want to use.
TPI (Time Proportional & Integral) is a self-learning, time-proportional algorithm.
TPI type of regulation ensures economical system operation through more accurate
temperature maintenance during controlling process and limits overload conditions. In
addition to the exact and stable room temperature, the advantage of this system is the
minimization of energy consumption and significant savings. RT520RF offers 3 types
of TPI control: 1. for radiator (6CPH); 2. for underfloor heating (3CPH); 3. for electric
heating (9CPH).
