ATAG Energion Nuos Plus 200 Ketel & boiler Handleiding

Gas Leak

Verify compressor inlet sensor proper functioning. If error persists, recover residual gas; find leak in cooling circuit; repair it; make vacuum and recharge circuit with 1100g of refrigerant gas

Compressor Issue

Check power voltage on compressor connector. Turn off the appliance

Evaporator Obstructed

Check that the evaporator and the external unit casing is not obstructed

Fan Issue

Check power voltage on fan connector. Control the proper functioning of sensor at compressor inlet

High Pressure

Check pressure switch wiring. Verify gas quantity

Compressor Thermal Protector: KO

Check compressor connector

Electronic Expansion Valve Issue

Verify expansion valve cables. Verify NTC suction and NTC Evap correct functioning

Dome NTC sensor (hot water): Open or Short Circuit

Verify NTC sensor (hot water) proper functioning

Water Temperature Sensor (Heating Element Zone): Open or Short Circuit

Check the correct assembly of sensor wiring on related mainboard connector. Verify sensor proper functioning

Water Temperature sensor (Heating Element Zone): safety intervention (1st level)

Verify sensor proper functioning

Water Temperature sensor (Heating Element Zone): safety intervention (2nd level)

Verify sensor proper functioning

Relay blocked

Reset the appliance by pressing the ON/OFF button twice. If the error persists, replace the motherboard

Impressed Current Anode: Open Circuit

Check the presence of water inside the product. If the error persists, verify the anode proper functioning. Check the correct assembly of anode wiring on related mainboard connector. If the error persists, replace mainboard

ON / OFF repeated

Wait 15 minutes before unlocking the product with ON/OFF button

Corrupted data

Reset the product by pressing the ON / OFF button twice. If the error persists, replace the motherboard

Missing communication between Main Board and HMI

Reset the product by pushing the ON/OFF button twice. If the error persists, replace the mainboard-display communication wiring

Mainboard – WiFi board missing communication

Check cables between motherboard and HMI. If the error persists, replace the HMI module. If WiFi not present: Enter to the Installer Menu and set P31 OFF. If the error occurs again, replace the Main Board

Mainboard – WiFi board missing communication

Check cables between motherboard and HMI. If the error persists, replace the HMI module. If WiFi not present: Enter to the Installer Menu and set P31 OFF. If the error occurs again, replace the Main Board

Missing Communication between Inverter and main board

Check the communication cable and the related motherboard and TDC cables. If the error persists, replace the TDC

Safety board communication failure

Reset the product by pressing the ON / OFF button twice. If the error persists, replace the motherboard

Touch screen not working

Reset the product by pressing the ON / OFF button twice. If the error persists, replace the HMI

Cascade master missing

Check that at least one of the products in the cascade is set as Master, otherwise set one

Oorzaak: Insufficient air flow to the evaporator

Clean the grilles and ducts regularly

Oorzaak: Product is switched OFF

Check the mains power supply. Switch the product ON

Oorzaak: Use of a significant amount of hot water when the product is in heating phase

Wait for the heating phase to complete

Oorzaak: Sensor error

Check for NTC errors, even occasional ones

Oorzaak: High level of limescale build-up in the boiler and components

Unplug the power supply, empty the appliance, remove the heating element sheath and clean the limescale from the inside of the boiler, taking care not to damage the enamel on the boiler and the heating element sheath. Reassemble the product in its original configuration. Replace the flange gasket

Oorzaak: Sensor error

Check for NTC errors, even occasional ones

Oorzaak: Time W value too low

Set a lower temperature parameter or a higher Time W parameter

Oorzaak: Installation performed with non-compliant electricity power supply (voltage too low)

Power the product with the correct voltage

Oorzaak: Evaporator obstructed or frozen

Make sure that the evaporator is clean

Oorzaak: Problems with the heat pump circuit

Check the display for error messages

Oorzaak: 8 days have not passed yet since initial start-up, Time W parameter change, or power failure

Wait 8 days

Oorzaak: Leaks or obstructions in the hydraulic circuit

Check the circuit for leaks, check the condition of the deflector on the inlet cold water pipe and the integrity of the delivery hot water pipe

Oorzaak: It is normal for some water to drip from the device on the delivery system

If the leak continues even after the heating phase, check the calibration of the device and the mains water pressure. To prevent water from dripping, an expansion vessel must be installed. Never obstruct the device's discharge outlet

Oorzaak: Presence of an internal obstruction

Check the moving components of the unit, clean the fan and other moving parts which could cause noise

Oorzaak: Some components are vibrating

Check the components connected using mobile clamps, ensuring the screws are well tightened

Oorzaak: Failure or electrical connection problems between the motherboard and the interface PCB

Check the connection status and the correct operation of the PCBs

Oorzaak: Power failure

Check the power supply

Oorzaak: No siphon or siphon is empty

Install a siphon. Ensure it contains the necessary amount of water

Oorzaak: Leaks or partial obstruction in the refrigerant gas circuit

Switch the product ON in heat pump mode, use a leak detector for the specific circuit
