The SP30 control panel is flashing red and has no control – what does it mean?

When the SP30 control panel flashes red and does not allow control, it means that the fire thermostat in the unit has been triggered. For safety reasons, control via the panel is disabled when this occurs. To resolve the issue, the fire thermostat must be reset inside the unit. It is also important to check the airflow, as insufficient air circulation is a common reason for the fire thermostat being activated. Check whether the filters are clogged and replace them if necessary, and make sure that the outdoor air intake grille is not blocked by leaves, snow or debris. If you are unable to resolve the issue yourself, we recommend contacting the service company that installed the system or the retailer where the product was purchased.
