It offers you optimum heating convenience and minimum energy consumption. The control unit enables you to operate your heating system to be able to combine your economical and ecological aspirations. Of course, your logamaric comfort is always priority. The control unit, which is regulated by the MEC2 programming unit, is set up at the factory for immediate use.

Naturally, you or your heating contractor can modify these default settings and adapt them to your individual requirements. The MEC2 programming unit is the central control unit.


Some functions which you may need are located behind a flap. The keys logamatc this flap enable you to make various adjustments. The control concept is: Your heating system offers a wealth of further useful functions. Some examples of these are: What you should know about your heating system 2 2 What you should know about your heating system Why should you become more familiar with your heating system?

Advanced heating systems offer many functions for saving energy without sacrificing comfort. Getting to know this heating technology may appear daunting at first, but after a short while logamattic will recognise the advantages you can gain from a heating system that is set logamatci to meet your personal requirements.

The more you are aware of the options offered by your heating system, the greater the benefit you will be able to logamaitc from it. How does your heating system work? Your heating system comprises the boiler with burner, heating control unit, pipework and radiators.

A DHW cylinder or an instantaneous water heater heats the water required for a shower, bath or washing your hands.

Subject to the loga,atic your heating system has been logamatiic, it can operate either purely as a central heating system or together with a DHW cylinder. The important thing is that the various components match each other. The burner combusts fuel e. Using pumps, this hot water is transported through the pipework to the consumers radiators, underfloor logamatjc system, etc.


Logamaticand – Subject to technical modifications. The burner [2] heats the water inside the boiler [1]. This heating water is transported by the pump [3] through the flow line [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 line [7], where the cycle starts again. The room temperature can be adjusted to your personal requirements using the thermostatic radiator valves [5].

All radiators are supplied with the same flow temperature. The heat transferred to the room depends on the radiator logamaatic and the heating water throughput. Therefore, the heat transfer can be manipulated via the thermostatic radiator valves. The heat demand of a room largely depends on the following factors: What you should know about your heating system 2 Why do you need a control loyamatic The control unit ensures convenient heat and economical consumption of fuel and electrical energy.

It starts the heat source boiler and burner and pumps when warm rooms or DHW are required. In doing so, it utilises the components of your heating system at the correct time. Furthermore, your control unit records different variables that influence the room temperature and compensates for these. What does the control unit calculate? Advanced control units calculate the temperature required within the boiler the loyamatic flow temperature subject to the outside temperature.

The relationship lohamatic the outside temperature and the flow temperature is described as the heating curve. The lower the outside temperature, the higher the flow temperature must be. The control unit can operate in three control modes: Heating circuit curve example x Outdoor temperature y Flow temperature 7 loamatic What you should know about your heating system Weather-compensated control With weather-compensated control, only the outside temperature captured by the outside temperature sensor is decisive for the flow temperature level.

Room temperature fluctuations through radiant energy from the sun, occupants, open fireplaces or similar external heat sources are then ignored. If you utilise this type of control, adjust the thermostatic radiator valves so that the required room temperature is achieved in the different rooms.

Room temperature-dependent control A further possible heating control method is room temperature-dependent control. Lgoamatic control unit calculates the flow temperature based on the set and actual room temperature. To be able to logamativ room temperature-dependent control, you need logwmatic room that is representative of your whole home.

All factors influencing the temperature in this “reference room” — where the programming unit is located — will also apply to all other rooms. Not every home has a room that meets these requirements.

Pure room temperature-dependent control has, in such cases, certain limitations. Should you, for example, open a window in the room where the room temperature is measured, the control unit will “think” that you have opened the windows in every room in your house and will begin to heat vigorously.


Or the logamatlc might apply: You measure the temperature in a south-facing room with different heat sources solar or other heat sources, e. Now the control unit “thinks” that it is as hot in every room as in the reference room; consequently the boiler output will be severely reduced so that, for example, the north-facing rooms will become too cold.

Weather-compensated control with room temperature hook-up Weather-compensated control with room temperature hook-up combines the advantages of the other two control modes. The required flow temperature, which is mainly loganatic to logamtic outside temperature, can be adjusted by the room temperature only to a limited degree.

This achieves improved maintenance of the room temperature within the room containing the programming unit, without completely ignoring the other rooms. With this kind of control you will also need to keep all thermostatic radiator logamatif in the reference room fully loagmatic. Why do the thermostatic valves have to stay fully open? If, for example, you want to reduce the room temperature in the reference room, and you therefore close the thermostatic valve further, the flow rate through the radiator is reduced and, therefore, less heat is transferred to the room.

This reduces the room temperature.

The control unit will endeavour to counteract the drop in room temperature by raising the flow temperature. However, raising the flow temperature does not raise the room temperature, as the thermostatic valve continues to limit the room temperature.

An excessive flow temperature results in unnecessary heat losses from boiler and pipework. At the same time, the temperature in all rooms without thermostatic valves increases due to the higher boiler water temperature.

With this kind of control you always need to keep all thermostatic radiator valves in the reference room fully open.

What you should know about your heating system 2 Why do I need a logamattic switch? What are heating circuits? Advanced heating systems are equipped with a time switch to save energy. With a time switch you can set up an automatic changeover between two different room temperatures, subject to time.

This enables you to set logamatid reduced room temperature at night, or other times when a reduced temperature is sufficient, whilst operating your heating system with the standard room temperature during the day.

A simple heating circuit comprises a heat source, a flow line, a radiator and a logaamtic line. A pump installed in the flow line circulates the heating water. You have four options for reducing the room temperature via the control unit.
