Information | Description |
|---|---|
Furnace pressure monitor triggered | The furnace safety pressure monitor was tripped by an impermissible partial vacuum. The unit switches off. |
Switching test active | A switching test is being performed. |
Forced operation active | Cyclic forced operation active. Any pumps and servomotors present are activated briefly to avoid them seizing up. |
Frost protection, volumetric flow regulation | The heating capacity of the PTC heat register is too low for the current volume flow or the current outdoor temperature. The volumetric flow is therefore reduced to achieve the minimum air inlet temperature needed for frost protection. |
Max. humidity value limit exceeded | The set max. humidity limit value was exceeded, excess humidity protection (increase in volumetric flow) is active. |
Volumetric flow, measurement active | Fans are operated in nominal ventilation level for a maximum of 3 hours. |
Communication: EnOcean | There is no communication between the EnOcean plug-in module and the main circuit board. |
Communication KNX | There is no communication between the KNX plug-in module and basic circuit board. |
Internet communication | There is no communication with the internet. |
Communication ModBus | There is no communication with the Modbus components. |
External safety shutdown | A connected external safety contact has tripped (terminal X2). There is no bridge on the control circuit board. The unit switches off! |
