Material losses - Never spray cleaning spray into the air slot. - Ensure that no moisture can enter the appliance. - If a pale brownish discolouration appears on the appliance casing, wipe it off with a damp cloth. - Clean the appliance when cold with ordinary cleaning prod-ucts. Avoid abrasive or corrosive cleaning products. NoteWe recommend having the control components checked as part of regular maintenance. Have a qualiﬁed contractor check the safety and control components no more than 10years after commissioning.7. TroubleshootingProblem Cause RemedyRoom does not get warm enough. Ap-pliance does not get hot.Temperature set too low on the appliance. Check the selected room temperature. Adjust if nec-essary. No power supply. Check position of the ON/OFF switch, RCD and fuse/MCB in your fuse box.Room does not get warm enough al-though the appliance is hot.Overheating. High limit safety cut-out limits heating output. Eliminate the cause (dirt or obstructions at the air inlet or outlet). Observe minimum clearances. The heat demand of the room is higher than ap-pliance output.Remove heat losses (Close windows and doors. Avoid constant venting.)Room gets too hot. Temperature set too high on the appliance. Check the selected room temperature. Adjust if nec-essary. Detected room tempera-ture does not match actu-al room temperature.Avoid obstructions to air change between appliance and indoor air.Window open de-tection does not respond. Appliance does not detect a pronounced tempera-ture drop due to venting. (Window open detection requires previously sta-ble room temperature.)Wait a while after making settings on the appliance, until the room temperature has fully stabilised. Avoid obstructions to air change between appliance and indoor air. Manually switch the appli-ance into standby mode for the duration of venting. Window open detection is not enabled. Switch on window open detection in the standard menu."Adaptive start" func-tion does not work as required.This function is only ef-fective in timer mode. Use the timer mode for opti-mised heating convenience. Severely fluctuating room temperature or the appli-ance learning procedure has not been completed.Wait a few days for behav-iour to stabilise. “Adaptive start” function is not enabled. Switch on the "Adaptive start" function in the stand-ard menu.Problem Cause RemedyAppliance is in "FP" program but does not respond to external input.When the appliance does not detect a signal at the external input, it heats in comfort mode.Check external control unit and its settings. Wiring must be installed correctly and with correct polarity."Err" or "E..." is dis-played.Internal fault detected. Notify the qualified con-tractor.If you cannot remedy the fault, contact your qualiﬁed contractor. To facilitate and speed up your request, provide the number from the type plate (000000-0000-000000).INSTALLATION8.
