3.2.13. Customizing Combi Features

As your combi has an advanced electronic card, operation conditions 

and certain parameters related with your preferences may

be changed by our Authorized Service. Please consult our authorized 

service when any changes requested in below given parameters.

(P06) (CH) (Heating) Power.

Combi is equipped with an electronic modulation with power suitable 

with actual heat requirement of installation place. Thus, the combi 

automatically operates with variable gas flow rates depending on heat 

load of installation between the minimum and maximum power.

(P07) Controlled Power Increase Period.

When combi starts, it uses a controlled period defined for reaching the 

adjusted maximum heating power. This period is adjusted as 3 minutes 

as standard and can be increased up to 3 minutes.

(P21) Low temperature region selection.

This parameter should be adjusted as 1 for ground heating or heating 

systems operating with low temperature. 0 (zero) value is selected for 

radiator systems to operate at high temperatures as standard.

(P24) Child Protection

Your combi is protected against setting changes with the child lock that 

is activated when the MODE button is pressed for 5 seconds.

Protection lock is activated when the parameter is adjusted as 1.

(P40) Radiator ignition delay period.

Combi device is equipped with an electronic timer for preventing 

frequent ignition by the combi during heating stage. This

period is adjusted as 2 minutes as standard and can be increased up to 

10 minutes.

(P42) Ready Hot Water (Pre-Heating passive/active).

In order to rapidly prepare the domestic hot water without your request 

and reducing the cold water consumption during waiting, it heats the 

grid water in plate exchanger and keeps as hot water.  This function 

can be activated in 6 buttons LAWAPLUS models.  Pre-heating function 

is activated when domestic hot water temperature increase Figure 28 

(2) RESET button is pressed until cycle is completed. At the end of this 

period, Pre-On (active), Pre-Off (passive) is seen on the LCD screen for 

5 seconds.

Activation of this function in LAWA models is enabled with parametric 

adjustment by our Authorized Service according to your request.

 

Air Discharge Function

Activating the menu for LAWA, PRIWA and ENERWA models:

Air discharge function can be activated by pressing the RESET button 

more than 5 seconds while CH button and DHW button are at 

maximum position. Upon activation of this function, 3 way valve and 

pump is operated or not operated for discharging the air within the 

radiator installation.

3.3. TROUBLESHOOTING

3.3.1. Failure Codes Table

 

Failure 

Code

Failure / Error Definition

Possible Reasons

Combi Status / Solution

E 02

Low water pressure in CH system / system 

parameter is wrong adjusted

Adequate pressure is not available in the 

radiator installation for efficient and smooth 

operation.

Control the manometer of your Combi, correct 

pressure value should be between 1÷1,2 bar, 

ensure correct pressure in case of being required.  

Press the RESET.

E 03

High water pressure in radiator system (in LawaPlus)

Excessive water pressure, safety valve.

Reduce the pressure from water discharge tap. Call 

the authorized service.

E 04

DHW Temperature Sensor failure.

In case the card detects failure or error in 

NTC domestic hot water sensor, combi notifies 

this error situation.

Combi is not functioning (1).

E 05

Radiator temperature Sensor failure.

Electronic card detected a failure in output 

NTC sensor. 

Combi is not functioning (1).

E 13

Exhaust Gas Temperature Sensor excessive 

temperature alarm.

Combi passes into failure due to excessive 

temperature of exhaust gas accumulated inside 

due to any failure during.

Call the authorized service in case of repeated 

after reset..

E 14

Exhaust Gas Temperature Sensor failure.

Electronic card detected an anomaly in 

exhaust gas sensor.

Combi is not functioning (1).

E 15

Fan failure (feedback/feeding).

Fan is blocked. Excessive external air pressure.  Call the authorized service in case of repeated 

after reset..

rE 06

rE 08

No ignition. Not ignited within the previously 

defined period in case of any request for  

radiator or domestic hot water production. 

Intervention may be required for removing the 

"ignition prevention status" at first ignition of 

device or after a long standby period.

Control whether gas supply line valves are 

open.  Respectively, control whether gas 

valves of your combi, home and building are 

open.

Call the authorized service in case of repeated 

after reset.

rE 07

Safety / Security Thermostat Intervention (dual 

CH sensor)

If internal excessive heating occurs due to any 

failure during normal operation, combi passes 

to failure status and 

Press the RESET button. (1)
