Information
Current information is displayed with date and time.
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 heater power rating of the preheating register is too low for the current volumetric 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. |
Brine EHE, low cooling capacity | The cooling capacity of the brine earth heat exchanger is too low. There is no cooling effect Pump is blocked for one hour. |
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! |
Night Cooling active (from firmware version 1.3.0) Displayed when function is active. For more info → | If the temperature conditions mean that cooling is not possible, fan operation is interrupted for 50 minutes. After this time elapses, the fan is started for 10 minutes and cooling is checked again. |
Flush Mode active (from firmware version 1.3.0) Displayed when function is active. For more info → | Fan operation with the air volume set by the user in the defined time frame, e.g. for maximum air volume exchange (max. 100 % adjustable). Start by weekly time programme (note wiring/configuration of sensor inputs). Display message: Flush Mode active. |
Motion detector mode active (from firmware version 1.3.0) Displayed when function is active. For more info → | Activated when motion detector registers a movement. Display message: Motion detector active. |
Sensor mode active (from firmware version 1.3.0) Displayed when function is active. For more info → | Activated when the sensor detectors trigger an operation. Display message: Sensor detector active. |
Volumetric flow compensation active (from firmware version 1.3.0) Displayed when function is active. For more info → | Is used to compensate for air extracted by exhaust air systems (e.g. fume hood) in the room. Supply air fan is operated with set air volume. Setting value depending on the respective unit type in m³/h. Display message: Volumetric flow compensation active. |
