necessary to connect an additional 1N4007 diode (1A, 1000V) in parallel to the relay coil, as indicated in Figure 37
At the stage of correctness verification of the connection and settings of the device, it is not recommended to include
actuators in the relay circuit directly. It is advisable to do this at the final stage of testing.

1-Wire controller interface (IButton) allows to connect up to 4 digital sensors like DS18S20 (DS18B20) to the device,
and it can also operate with DS1990 keys or key / card readers that emulate DS1990 keys via interface 1- Wire.
Each DS1990 key is a chip with a unique identification number stitched into it at the manufacturing plant by which
the device identifies this sensor.
Saving the key codes in the device's memory allows to use identification when changing the security mode, activating
the output with the profile set: "TM registered key indicator" and "TM key indicator", and also necessary for operation of
the "Immobilizer" function.
The maximum number of stored keys - 16.
It is also allowed to connect external readers of contactless Proximity-cards and keyfobs that have TouchMemory
DS1990A key emulation interface. However, such readers, as a rule, do not operate together with thermal sensors
connected to the same physical interface.
