2. Product Overview
The RT520 room thermostat simply switches the heating system on and off 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
off 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 affect 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 off.
The way to set and use your room thermostat is to find 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 18C 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 different
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 flow of air to sense the temperature, so they
must not be covered by curtains or blocked by furniture. Nearby electric
fires, 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 significantly increase the energy efficiency 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 off.
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 floor level far
from heating or cooling sources. Thermostat can’t be exposed to sunlight or
any extreme conditions like for example draft. Because of fire and explosion
risk there is not allowed to use thermostat in atmosphere of explosive gases
and flammable 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).
