Komfovent ısı geri kazanım cihazı All models error codes
Codes
- F1Error codeToo high resistance of the ventilation system
- F3Error codeThe temperature of the return water in the water heater has dropped below the acceptable limits
- F8Error codeIcing may occur in low outdoor temperatures and in high room humidity. Alarm may also appear if icing protection is turned off and outdoor temperature drops bellow -4°C.*
- F9Error codeRisk of fire in the ventilation system
- F10Error codeFire alarm from the building’s fire protection system
- F11Error codeDisconnected or faulty tem perature sensor(s)
- F23Error codeInner main controller failure
- F28Error codeNo signal from integrated temperature/humidity sensors inside of control panel
- F30Error codeFor unit operation needed air-quality/humidity sensor not connected or broken
- F46Error codeExternal fire alarm received from fire damper controller
- F51Error code1. Integrated heaters malfunc tioning. 2. Faulty air temperature sensor
- W4Error codeOne of two humidity sensors not connected or broken. An other connected sensor is used for unit operation
- W5Error codeOne of two air impurity sensors not connected or broken. An other connected sensor is used for unit operation
- W6Error code1. Message can appear if air is extracted through additional 5-th duct and because of that heat-exchanger efficiency is low (only DOMEKT R units). 2. Supply fan intensity is set much higher than extract fan. 3. AHU doors are not closed properly thus diferent airflows are mixed
