Introduction 1 1 Introduction When you purchased your Logamatic 2107 controls, you chose a controls that makes it very simple to control your heating system. It will help you optimize your heat output while minimizing energy consumption. With the Logamatic 2107 controls, you can run your heating system in a way that takes full account of all your financial, environmental and health needs. However, your personal comfort takes always priority.
1 Introduction About this manual Chapter 2 contains a synopsis of heating systems and their controls. Chapter 3 gives you some tips on energy-efficient heating. In Chapter 4 you will find some important notes on using the controls safely. Chapter 5 explains how to get started with your controls. The "basic functions" are illustrated in Chapter 6. Generally these functions are sufficient to fine-tune your heating system to your personal requirements.
What you should know about your heating system 2 2 What you should know about your heating system Modern heating systems offer many functions for saving energy without sacrificing comfort. The first step in getting acquainted with this heating technology is the most difficult. After a short while, however, you will recognize the advantages of a heating system which is adjusted to your personal requirements.
2 What you should know about your heating system Fig. 1 shows the heating circuit of a pumped central heating system: The burner (2) heats the water inside the boiler (1). This heating water is propelled by the pump (3) through the supply pipe (4) to the radiators (6). The heating water flows through the radiators, and in doing so, gives off some of its heat. The heating water flows back to the boiler via the return pipe (7); there, the circuit begins again.
What you should know about your heating system 2 Why do you need a heating system controls? The heating controls ensures comfortable heat and economical consumption of fuel and electrical energy. It switches the heat generator (boiler and burner) and pumps ON, if there is a heat demand. In doing so, it utilizes the components of your heating system at the correct time.
2 What you should know about your heating system Outdoor reset temperature control With outdoor reset temperature control, the outdoor temperature is taken into account to determine the supply temperature. Room temperature fluctuations through solar irradiation, occupants, open fireplaces or similar external heat sources are not considered. If you use this type of control, adjust the thermostatic radiator valves (if installed) so that the desired room temperature is obtained.
What you should know about your heating system Why do I need a timer? Modern heating systems are equipped with a timer to save energy. This allows setting up an automatic changeover between two different room temperatures, subject to time, e.g. a reduced room temperature at night, while operating your heating system with the standard room temperature during the day. You have four options for reducing the room temperature.
3 3 Tips on energy-efficient heating Tips on energy-efficient heating Here are a few tips on how to heat economically, without sacrificing comfort: – Only heat if you need warmth. Use the preset heating programs (standard programs) on the controls or those which you have tailored to your personal needs. – Heat in an energy-conscious manner during shoulder seasons too, and make use of the warm weather shutdown (WWSD) function (see Chapter 7 "Extended functions", page 28).
