Reason
Actual fan speed differs from the unit rpm setpoint.
Cause:
An incorrect fan speed is detected.
Corrective Action:
Check the 4 wired fan control wiring and connections at the fan and at the main control board.
Check the 3 wired power supply wiring and connections at both ends.
Replace the fan.
Replace the main control board.

Reason:
High-temperature limit thermostat has exceeded the limitation value.
Cause:
The water flow is restricted.
Corrective Action:
Check for correct operation of the integral pump.
Check that all valves that may restrict the water flow through the boiler are fully open.
Ensure that any strainers installed in the primary circuit are free from debris.
Check for an external system pump that influences the flow through the unit.
Check if the system resistance exceeds the spare capacity of the integral pump.
This message occurs to confirm the end of programming. Pressing RESET will return the unit in normal operating status.
Unit was not in stand-by mode when an attempt to program the parameters was made (fan must not run during
programming).
