Hello! Today, the heating gas boiler Rocterm TD-B18 was repaired
The reason for calling our service was the failure of the heater!
On the screen there was a constant flashing error, which even does not exist in the manual to the instrument!
This error is associated with a slaughter in the hidden memory of the system board of the device.
We withdrew the fee for recovery!
After reprogramming the board, the error was eliminated and the device returned to normal operation
