  • This error message is produced by background processes that have greater than typical disc access (backup programs, virus scans, and so on). Close any background programs, then simply close and restart the MEmu software to solve the problem.
  • Now, when two or more copies of the S30 or E30 emulation applications are running together, this error notice seems to. Close all copies of the emulation programs and start afresh to solve the problem.

The Thermostat has found an unknown device on the system

  • In or out of configuration mode, an unaware device is discovered on the network. Clear the system by reconfiguring it. You need to select the setup tab, then start and confirm. If the problem stays, you have to double-check all DEVICE connections for unsuitability.

The Thermostat Cannot Find a Previously Installed Unit

  • You simply need to check all connections and turn on the power to the system. If the problem continues, clean the system by reconfiguring it. After that, you need to select the setup tab, then start and confirm. If the problem remains double-check that all DEVICE connections are icomfort-compatible.

The thermostat found more than one thermostat and more than one indoor unit, or more than one outdoor unit on the system.

  • Check to wire and eliminate duplicate kits. Reconfigure system.

The thermostat is reading an indoor temperature that is lower than 40? F. The thermostat will not allow any cooling operation to begin until it senses a temperature higher than 40F

  • Indoor Temp fell below 40F Cooling operation is not permitted. You need to check to make sure that the cooling equipment is not stuck ON. Check the precision of the thermostat temperature sensor. You simply need to select the heating system mode to heat the indoor space to above 40F.

The system has been cooling for at least 15 minutes, without a demand for cooling.

  • You need to run the system in diagnostic mode to make sure it matches the real functionality of the gear. Check for any added alerts or codes that might be interfering with the system’s normal operation.
  1. You simply need to check all cooling equipment to determine the cause of cooling demand.
  2. After that, simply recycle power.
  3. The system will clear the code when it notices the condition has cleared.
  • Equipment is incapable of communicating. This might specify the existence of other alarms/codes. In most cases, errors are related to electrical noise. You need to make sure high-voltage power is detached from RSBus. Check for miswired and/or loose influences between the stat, indoor unit, and outdoor unit. Also, Check for a high-voltage source of noise close to the system. Usually, this is a self-recoverable error.

The thermostat is understanding indoor temperatures below the pre-programmed limit.     

  • You need a recalibrated thermostat to clear; also warm the thermostat; simply adjust the set point. Replace the thermostat, if desired.
