29Eco Mode Selection

Eco/Reset key has two functions:

1. If the Eco/Reset key is pressed while in error mode, the error is reset.

2. In normal operating mode, Eco mode is activated or deactivated by the Eco/Reset key.

Entry to the Eco mode: If Eco/Reset button is pressed shortly in winter mode, Eco mode becomes active and "Eco" symbol appears on the heating screen.

Exit from the Eco mode: When Eco mode is active in winter mode, Eco mode becomes passive and "Eco" symbol does not appear on heating screen if Eco/Reset

tbutton is pressed shortly.

1.7. Failures and Warnings

Error

Code Error Name Error Type Explanation and Corrective Action

Overheating safety

thermostat lockout error Lockout Error If the overheating safety thermostat contacts remain open for 3 seconds, this lockout error is given. To correct this error, the contacts of the overheating safety thermostat must be short circuited. Restart your product by pressing the Reset key.

F01

Flame detection lockout

error Lockout Error This lockout error is given after 3 unsuccessful ignition attempts for natural gas type and 1 unsuccessful ignition attempt for LPG gas type. To clear the error, restart your product by pressing the Reset button.

F02

Domestic water

temperature sensor error Self-Clearing Error

This warning is given when the domestic hot water temperature sensor is short circuit or open circuit. In this case, central heating operation is done normally.

Domestic water heating operation is performed according to the

central heating flow temperature sensor as described in the domestic water heating operation section. When the domestic water temperature sensor starts to measure normal values, the warning is corrected automatically.

F03

Central heating water flow temperature sensor error

Self-Clearing Error

This error is given when the central heating water flow temperature sensor is short circuit or open circuit.

Central heating and domestic water heating cannot be carried out. When the central heating water flow temperature sensor starts to measure normal values, the warning is corrected automatically.

F04

Central heating water flow temperature sensor error

Self-Clearing

Error This error is given when the central heating water flow temperature sensor is short circuit or open circuit.

Central heating and domestic water heating cannot be carried out. When the central heating water flow temperature sensor starts to measure normal values, the warning is corrected automatically.

F05

Air pressure switch open circuit error

Air pressure switch open circuit error

Self-Clearing Error

Self-Clearing Error

This error is given if the air pressure switch remains open circuit for 25 seconds despite the fan is running. The fan and the pump are controlled as described in the APS open (F06) function. If the air pressure switch contacts are short circuited while the fan is on, the error is cleared automatically.

This error is given if the air pressure switch contacts remain short circuit for 15 seconds despite the fan is not running. If the air pressure switch contacts are open circuited the error is cleared automatically.

F06

F07

Low or high water

pressure error Self-Clearing

Error Water pressure sensor configuration

If the water pressure is <0.4 bar, this error is given.

If the water pressure is ≥ 0.8 bar, this error is cleared automatically.

If the water pressure is> 4.0 bar, this error is given.

If the water pressure is ≤ 3.5 bar, this error is cleared automatically.

Water pressure switch configuration

If the water pressure switch contacts remain open for 3 seconds, this lockout error is given. If the water pressure switch contacts are short circuited the error is cleared automatically.

1.7. Failures and Warnings

• Please follow the table above when your product indicates any error code.

• Make sure that gas is supplied to your product and if necessary, contact your nearest COPA authorized service.

• Do not interfere with your product other than COPA authorized service, change parameters etc. Please note that in these cases, your product will be out of

warranty.

Error

Code Error Name Error Type Explanation and Corrective Action

Central heating water flow

overheating error Self-Clearing Error

When the temperature of the central heating flow rises above 95° C, this error is given and the device is stopped.

When the temperature of the central heating flow drops below 95° C, the error is corrected automatically and the device starts to work.

F09

Circulation error Self-Clearing

Error If the central heating water flow temperature is 40° C higher than the central heating water return temperatu-re, this error is given. If the central heating water flow temperature is not higher than the central heating water return temperature by 40° C, this error is cleared automatically.

During the heating of the domestic water, this error is not controlled within the first minute after the heating of the domestic water is finished and within the first minute after the device is ignited. If one of the heating water flow or return temperature sensors is defective, this error is not controlled.

In this case, call your nearest COPA authorized service as soon as possible.

F10

Central heating water flow temperature sensor and return temperature sensor are installed reversely error.

Self-Clearing

Error If the central heating water return temperature is 7° C higher than the central heating water flow temperature for 4 minutes, this error is given. If the central heating water return temperature is not higher than the central heating water flow temperature by 7° C, this error is cleared automatically.

This error is not controlled during the heating of domestic water. If one of the heating water flow or return temperature sensors is defective, this error is not controlled.

In this case, call your nearest COPA authorized service as soon as possible.

F11

Flame detection circuit

material failure Self-Clearing

Error This error is given if a signal outside the expected limits from the flame detection circuit is detected for a duration of 15 seconds. If a signal within the expected limits from the flame detection circuit is detected for a duration of 2 seconds this error is cleared automatically.

F12

Surprise flame detection

error Self-Clearing

Error This error is given if the flame signal is detected unexpectedly for 10 seconds even though the gas valve is closed. The device stops working within these 10 seconds. If the unexpected flame signal is corrected, this error is cleared automatically.

F13

Gas valve feedback

lockout error Lockout Error If an error occurs in the gas valve drive or gas valve feedback circuits, this lockout error is given. To clear the error, restart your product by pressing the Reset button.

1.9. Maintenance

In order for your product to operate safely, efficiently and trouble free, we recommend that you have maintenance done at least once a year by authorized COPA services.

2.0. Warnings

The safety valve outlet should be connected to a drain or collecting pipe to prevent water from spilling on the floor in case of overpressure in the heating circuit. Otherwise, if the room is flooded as a result of opening the safety valve, COPA cannot be held responsible for this case. Before making the connection, make sure that the device is set to work with the current fuel type and carefully clean all the pipes of the installation.
