How to configure a thermostat?

To do this, at first, each user should determine comfortable air temperature. The thermal sensations of each person are individual, as the papillary lines of the skin on fingers of his hands, and depend on the thermal losses of the room and its thermal response rate.

The most obvious example is the adjustment of the thermostat of the electromechanical type. After selecting the temperature using the rotating wheel, keys and scale, the thermostat with its sensor comes into operation. The latter monitors the level of air or floor temperature and transmits this value in the form of a signal to the regulator. And it, accordingly, turns on or off the heating device or cable as necessary. The purpose is to maintain the specified temperature or its permissible range.

It is recommended to use the electromechanical (non-programmable) thermostat when the heated room has a small volume and energy costs. Therefore, the economic effect of programming modes will be stealthy. Electromechanical thermostats are simple, non-volatile devices that are most affordable. On the other hand, they introduce greater response rate into the control process. It takes longer to reach a set temperature for such thermostats than digital ones.

In fact, all types of thermostats operate with a set point temperature. When the temperature is reached, the heating device is disconnected from the power supply circuit and is switched on only after this value drops by the hysteresis value. It clearly determines when the heating device is on and off. The set point of the thermostat depends mainly on the field of its application. For heating floors, convectors and infrared heaters, it lies in the range (0... 60), industrial applications and electric boilers (-55... + 125), snow melting systems (-20... + 10) ° С. Some technical solutions relate to high-temperature processes.

Hysteresis is defined as the temperature difference between turning the heater on and off. Hysteresis can be fixed or changeable (adjustable). In the latter case, the minimum hysteresis possible allows the thermostat to maintain the temperature most accurately. But at the same time, the on/off cycles of the heater will alternate very often.

For thermostats working in the Cooling mode, the load will be switched on when the setpoint temperature is reached and off when it increases by the hysteresis size.

Additional settings for digital thermostats

For all thermostats of this type, a correction is available to adjust the temperature values on the screen. The second group of corrections is typical only for thermostats with an integrated temperature sensor. In this case, the accuracy of the thermostat values is affected by its internal heating. The degree of the latter depends significantly on the connected load. Therefore, it is necessary to adjust the thermostat by adding its power value to the memory of the device.

It is important to remember the following. If, during calibration, the power supply of the thermostat is switched off for a short time and then restored, then the air temperature displayed on the screen differs from the real one by 10 - 12 ° C (upwards). A re-adjustment will occur in 50 minutes. Digital types of thermostats controlled by the WI-FI module or keys have button locks. This prevents unauthorized changes in settings by children (at home) or when installing control devices in public areas (administrative buildings, etc.). Moreover, you can set up a thermostat to maintain this protection using ordinary or touch buttons or using a remote method - through a computer or mobile gadgets with Internet access.

With some models of thermostats, you can adjust the time (30 minutes - 99 hours) of on-delay (power supply) of the heating system or device. For some time there will be no people in the apartment/house. Knowing approximately the period of your return, you can warm up the rooms in advance to create comfortable conditions.

Control devices of snow and ice melting systems there are functions of forced and subsequent heating. Forced is implemented during manual control of the melting system. And subsequent heating (post-heating) is required to completely remove precipitation from the entire surface area, which the precipitation sensor does not monitor.

Programmable thermostats

Separately, it is worth considering thermostats-programmers with the possibility of introducing a schedule for heating systems. Such thermostats have implemented programming for the week ahead. I.e. each user selects an individual operating schedule for heating, which fully corresponds to the schedule of a person and his family. This takes into account the procedure for alternating working days and weekends. There are possible modes " Timer," "Manual" and "Departure."

terneo programmable thermostats include ax, sx, rzx, pro and pro-z models. The first three are programmed remotely, via Wi-Fi, the rest by using buttons. In the "Timer" schedule mode, you can set the programmer with the buttons to a maximum of three, and for Wi-Fi - there are sixteen periods of maintaining a comfortable temperature during the day. In periods between them (i.e.

at night, during the working time of the day, etc.), the economical temperature (15-16) ° С is kept. This value is considered expedient in terms of energy consumption and for a prompt return to comfort. Similar temperature parameters are maintained during the period of relatively long absence of people ("Departure" mode). The "manual" mode corresponds to constant maintenance of the specified temperature value. All this contributes to the maximum possible energy savings.

No less useful will be the room ventilation settings, when the thermostat independently determines the presence of an open window or door and makes a half-hour break in the operation of the heating system.

In terneo pro programmer, you can activate preheating to ensure comfort in the room in a timely manner. The regulator analyzes the average heating time from economical to comfortable temperature and corrects the required load connection time.

To optimize energy costs, the consumer needs to set the thermostat to store energy statistics (daily, weekly, monthly or per year). For some regulators, a more simplified version is available - the time counter for its operation with load.
