Let’s talk about the heating control unit of a country house


Autonomous heat­ing is an urgent need for own­ers of coun­try hous­es who do not have the abil­i­ty to con­nect to the high­way. Like any piece of equip­ment, it needs to be fine-tuned to achieve max­i­mum oper­a­tional effi­cien­cy. Mod­ern tech­nolo­gies allow you to install a heat­ing con­trol unit for a pri­vate house remote­ly, using a cell phone, the Inter­net and oth­er com­mu­ni­ca­tion meth­ods. This approach makes it pos­si­ble to receive time­ly noti­fi­ca­tions of an emer­gency, remote­ly issue com­mands to turn off the sys­tem, adjust the tem­per­a­ture by send­ing mes­sages in accor­dance with your own require­ments.

Basic working principle

The main detail in the whole scheme is an elec­tron­ic con­trol unit, which pro­vides slots for installing stan­dard SIM cards for cel­lu­lar com­mu­ni­ca­tion. More tech­no­log­i­cal mod­i­fi­ca­tions also have a con­nec­tor where an elec­tron­ic Inter­net cable is con­nect­ed. Sim­i­lar­ly, tem­per­a­ture sen­sors, pres­sure indi­ca­tors, fire alarms and oth­er secu­ri­ty sys­tems are con­nect­ed to this mod­ule. Of course, to pro­vide feed­back, the unit itself must be con­nect­ed to a heat­ing boil­er.

The heat­ing con­trol of a coun­try house is car­ried out accord­ing to a sim­ple, in gen­er­al, scheme. The ini­tial adjust­ment of the func­tion­ing is car­ried out, after which the cen­tral proces­sor fix­es in the mem­o­ry the cor­rect oper­at­ing con­di­tions of the sys­tem. If one of the con­nect­ed sen­sors sends a sig­nal about a change in these con­di­tions, for exam­ple, the tem­per­a­ture starts to drop, a text mes­sage is sent to the own­er’s cell phone. The own­er, in turn, can request the read­ings of oth­er sen­sors in order to more ful­ly assess the sit­u­a­tion, send a response com­mand with a text mes­sage to turn off the devices or con­tin­ue work­ing as usu­al.

The heat­ing con­trol sys­tem can also be based on com­mu­ni­ca­tion through the use of the Inter­net. To do this, on a cell phone with access to the glob­al net­work, you must first install a spe­cial appli­ca­tion that demon­strates all the cur­rent sys­tem para­me­ters in real time.

Tangible benefits

Con­sid­er a few sit­u­a­tions in which the scheme is guar­an­teed to be use­ful:

  • You return to the cot­tage from a week-long busi­ness trip or vaca­tion, dur­ing all this time no one lived there. On the way from the air­port, you send a text mes­sage, send a sig­nal to start heat­ing. By your arrival, the micro­cli­mate in all rooms will be as com­fort­able and pleas­ant as pos­si­ble.
  • You set the boil­er to an eco­nom­i­cal mode, which excludes freez­ing of the coolant in the pipes, and leave. Unex­pect­ed­ly, a fail­ure occurs, the coolant cools rapid­ly, the mod­ule detects an acci­dent, sends you a mes­sage. You, in turn, send a response com­mand to restart the boil­er. If this mea­sure does not bring results, it is worth call­ing the emer­gency ser­vice. This method elim­i­nates the pos­si­bil­i­ty of freez­ing of the coolant in the pipes, which will inevitably lead to a rup­ture and huge finan­cial costs for restora­tion.
  • If you want to know the cur­rent sit­u­a­tion in the house, send the appro­pri­ate com­mand. The response mes­sage con­tains infor­ma­tion about the air tem­per­a­ture in the con­trolled premis­es, the lev­el of humid­i­ty, and the cur­rent tem­per­a­ture of the sys­tem coolant.
  • A dan­ger­ous sit­u­a­tion arose with the gas boil­er: the fuel sup­ply cir­cuit was depres­sur­ized, there is a high con­cen­tra­tion of the com­po­si­tion. With a response mes­sage, the heat­ing sys­tem is trans­ferred to a back­up ener­gy source, the prob­lem is elim­i­nat­ed by spe­cial­ized ser­vices.

Set of modules and installation features

Heat­ing con­trol in a coun­try house accord­ing to the GSM stan­dard requires the fol­low­ing ele­ments:

  • A unit equipped with slots for installing cel­lu­lar cards and pow­er cables.
  • Aux­il­iary remote anten­na that improves sig­nal qual­i­ty.
  • An inte­grat­ed bat­tery that main­tains the device’s per­for­mance when the cen­tral­ized pow­er sup­ply is turned off. Please note that with autonomous pow­er, func­tion­al­i­ty decreas­es sig­nif­i­cant­ly. For exam­ple, the unit will not be able to send a sig­nal to restart the gas boil­er, there sim­ply is not enough volt­age for this. The built-in bat­tery should last approx­i­mate­ly 3 days of oper­a­tion. Many mod­els require the con­nec­tion of an addi­tion­al pow­er source.
  • tem­per­a­ture sen­sors. In most cas­es, their max­i­mum num­ber is lim­it­ed to five.
  • Addi­tion­al sen­sors for secu­ri­ty and fire alarms, water sup­ply break­throughs, unau­tho­rized open­ing of win­dows and doors.

Thus, not just a heat­ing con­trol sys­tem, but a full-fledged secu­ri­ty com­plex can be formed in the house.

If we talk about the nuances of instal­la­tion, then there are no par­tic­u­lar dif­fi­cul­ties. All devices are fixed as eas­i­ly as pos­si­ble. To elim­i­nate the pos­si­bil­i­ty of fail­ure, we rec­om­mend mount­ing the con­trol unit in a room where the most sta­ble and clear cel­lu­lar net­work sig­nal is record­ed. It is also worth con­tact­ing the oper­a­tor so that adver­tis­ing mes­sages from unknown num­bers do not come to the SIM card in the block, such inter­fer­ence often caus­es fail­ures.


The min­i­mum set of func­tions that con­trol and con­fig­ure the heat­ing sys­tem of a mul­ti-storey build­ing is as fol­lows:

  • Set­ting the air tem­per­a­ture in the premis­es and the tem­per­a­ture of the coolant;
  • For­ma­tion of a text report indi­cat­ing all oper­at­ing para­me­ters and fur­ther send­ing to the own­er’s phone;
  • Deter­mi­na­tion of volt­age sta­bil­i­ty in the home pow­er net­work;
  • Con­trol of devices in case of an emer­gency, includ­ing emer­gency shut­down of the boil­er;
  • Main­tain­ing the tem­per­a­ture in the premis­es at a giv­en lev­el, its remote adjust­ment.

Addi­tion­al func­tion­al­i­ty depends on the exact mod­el of the automa­tion unit, a set of con­nect­ed sen­sors. Prac­tice shows that the fol­low­ing func­tions are most use­ful:

  • Con­trol over pres­sure and fuel lev­el in diesel and wood-burn­ing devices;
  • Track­ing unau­tho­rized access;
  • Acti­va­tion of a fire alarm in the event of an open fire, smoke, a sharp increase in tem­per­a­ture;
  • Leak track­ing.

Please note that some blocks involve com­mu­ni­ca­tion not with one num­ber, but with nine at once, they are designed for storey build­ings.


It turns out that the automa­tion of the heat­ing sys­tem is a prof­itable and jus­ti­fied solu­tion from all sides. The effi­cien­cy of oper­a­tion increas­es, the risk of an emer­gency sit­u­a­tion is elim­i­nat­ed, the com­fort of liv­ing reach­es its max­i­mum lev­el. With all these advan­tages, the cost of set­ting up such a sys­tem is demo­c­ra­t­ic, the devices will pay off in just a sea­son or two!
