Communication problem



The HCL controller has a total of 12 thermostats. Everything worked great last season. But recently I discovered communication problems. All nodes are dead. Moreover, it can be seen that the data from the temperature sensors are being updated, but it is impossible to change the temperature setpoint. Communication problem.
