The equipment for air heating works as follows.

In the heating day mode, the controller 10 is connected to the controller 10 via a contact 16 and the automatic control system maintains the daily temperature in the room measured by the sensor 40. If the air temperature deviates from the set value, the controller 10 through the starter 6 and the actuator 5 changes the amount of heat carrier passed through the heater 2 to the required value depending on the sign of the change of the controlled parameter. At the same time, the contact 18 of the relay 15 is closed and supplies power to the sources 35 and 36 of the light illuminating the photosensors 33 and 34. The contact 22 of the relay 21 is closed and shunts the resistor 27 defining the night flow of the fan 7, and the contact 23 of the same relay is open and de-activates resistors 28 that split the fan's daily supply 7. From the output of the rectifier 30 through -, the contact 20 and the resistors 28, the voltage is applied through the block 25 to the excitation winding 39 of the slip clutch 24. The applied voltage determines the degree of adhesion and slip between each other of the coupling half (stator and rotor) of the coupling 24, thereby changing the frequency of rotation of the fan 7 When entering and leaving the room, people cross the light rays from sources 35 and 36, which registers photo sensors 33 and 34. The sequence of intersection of the rays and, consequently, the direction of movement of people using photo relay 31 and 32 is recorded

a reversible pulse counter 37, which supplies control signals to the traveling electromagnets 41 of the searcher 26, which moves its moving contact 42 over the contact field and shunts a certain number of resistors 28. The direction of movement of the contact 42 depends on the direction of movement of the person through the doorway.

In the night mode:: :: ti: 1-111I after the closing of the rykey key 38, the voltage is applied to 15 and 21, Relay 15 switches its contact 16 and P1:) to the regulator 10, the receiver 12, which sets the night temperature of the air in the room below dgvevnoy. At the same time, raem1) 1ko ko 1Tact 18, disconnecting the lamps 35 and 36 of the people counting circuit, and contact 17 closes. At the same time, the regulator 10 through the starter 6 covers the 4 g valve; using the mechanism 5 and reduces the flow of coolant through the heater 2 until the temperature after the heater becomes the desired temperature. After this, the temperature relay 19 triggers. 11ptel; but H-; iCTj) oeh to this temperature, and closes its contact 20, Through contacts 17 and 20, the voltage on r on-duty network is fed to relay 21, which closes contact 43, providing power to its winding, opens its contact 22 J input BUenij of the control resistor 27, I;: whose magnitude determines the supply of the fan 7 in the night mode, and the contact 23 bypasses the resistors 28 of the day mode. For example; The block 30 is delivered to block 2 via a night mode resistor 27. As a result, a smaller voltage is applied to the field winding of the coupling 24, which weakens the degree of coupling between the stator and the rotor of the coupling 24 and a lower rotation frequency is transmitted to the fan 7 Corresponding to the supply of fan 7 in the night heating mode. The supply air temperature is stabilized by the regulator 10 by adjusting the amount of heat through the heater 2. The use of the temperature relay 19 improves the quality of regulation by eliminating overheating of the air when switching to the night heating mode.

When the standby illumination 14 is switched off by the switch 38, the relays 15 and 21 are de-energized. At the same time, the relay 15 switches its pin 16 to the set-point 11 day mode, connecting it to
