2. Product Overview

The RT520 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 have TRVs, 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 the TRVs.

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:

• automatically detects OT + 4.0 protocol and regulates hot water temperature

• possibility to choose Hysteresis or built-in TPI 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)

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.

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. RT520 offers 3 types of TPI control: 1. for radiator (6CPH); 2. for underfloor heating (3CPH); 3. for electric heating (9CPH).
