Temperature control with Modbus thermostats during the cold winter months represents a lot of effort and understanding of how to keep as much heat in the rooms as possible. Proper handling can bring you huge energy savings on your energy bills. Thermal insulation, better and new materials, technology, etc. are only a handful of things that new technology have improved significantly in the last couple of years. In winter, the question is how to retain internal heat, while in summer, how to protect the premises from the intrusion of heat.   Despite all that, the greatest heat loss is represented by glass on windows and doors. These losses cannot be avoided, but with the correct handling of technology, automation of heating or cooling processes, we can help to keep them to a minimum.   We will introduce you to the best and most effective ways to control the temperature, especially in the coldest months. From mid-September until April, we usually have the strongest heating season. During this time, our homes consume up to 70% of all energy that is consumed throughout the year.   The most basic or standard temperature control in almost all of our homes is to control it with a smart Modbus thermostats. There are many different types of thermostats and many different uses cases. The thermostats can be simple or very complex. At Etop,we have designed and developed for you the extremely good, reliable and at the same time very affordable Modbus Fan Coil Thermostat.   The  Modbus thermostats allow, depending on the model, the control of a two-pipe or four-pipe system. This means that it can be used to operate also underfloor heating systems, heat pumps, HVAC systems, etc.   The standard functionality of both is that they have the ability to control the fan speed – usually 3 levels (low, medium or fast) and that they can be turned completely on (on) or off (off). In cooperation with motion sensor or a energy-saving switch, the thermostats can automatically switch to the Eco mode which has to be determined by user needs.   Both thermostats are extremely easy to operate. The most importantly both of them support the Modbus protocol, which means that they can be connected to an already comprehensive ecosystem, or enable easier installation and connection in new constructions
