Dampers should be checked on the following issues in the periods specified in the maintenance plan. If problems are 
encountered after the control, the Problem-Solving section should be examined. If the problem could not be solved 
despite this, AERA Technical Team should be contacted. 

• 

Can the dampers open and close smoothly?

• 

Is there any wear/laceration/detachment on damper seals? 

• 

Are there any crooked/broken/cracking/crushing of damper blades?

5.3.10  

Body Cleaning

The interior and exterior surfaces of the switchboard should be checked within the period specified in the maintenance 
plan. Regarding the negativities detected because of the control, the “Problem Solving” section should be examined 
first, and if the problem cannot be solved, the AERA Technical Team should be contacted. Control points are as follows. 

• 

Are there any knocks/dents/splitting in the body of the unit?

• 

Is water leaking from the appliance?

• 

s there any visible corrosion or wear on the outside of the unit?

• 

Are the doors dropping?

Use a damp cloth for body cleaning.

5.4 Alarms

 

 

 

 

This section should be reviewed by a person with sufficient knowledge of electric-

ity. Appropriate precautions must be taken before any intervention.

ALARM

PRIORITY

THINGS TO DO

1

SAF Failure

B

The ventilator fan needs to be checked.

2

EAF Failure

B

The extractor fan needs to be checked.

3

P1 HEATER FAILURE

B

Heater pump failure. Check if the unit has a pump outlet. Check 
the pump.

4

P1 COOLER FAILURE

B

Cooler pump failure. Check if the unit has a pump outlet. Check 
the pump.

5

P1 EXCHANGER FAILURE

B

Heat exchanger pump failure. Check the pump.

6

FILTER ALARM 1

B

Check if the filter on the supply side is dirty.

7

FIRE ALARM

A

Check the fire status information connections.

8

EXTERNAL SWITCHING

C

External start warning.

9

EXTERNAL ALARM

B

External alarm warning.

10 SUPPLY AIR CONTROL 

ERROR

B

It is an alarm indicating that the difference between the supply 
temperature set value and the reading air temperature is too 
high. Whether there is hot water in the system, the valve motor 
opened, the status of the bypass valve, etc. do checks.

11 HIGH SUPPLY 

TEMPERATURE ERROR

B

The supply air is above the specified limit. Check the heating 
actuator or electric heater.

12 LOW SUPPLY 

TEMPERATURE ERROR

B

The supply air is below the specified limit. Check cooling valve 
or DX Unit.

13 HIGH ROOM TEMPERATURE B

Room temperature is above the specified limit. Check the 
temperature control equipment. Heater valve, DX Unit, etc.

14 LOW ROOM TEMPERATURE B

Room temperature is below the specified limit. Check 
refrigeration control equipment. Refrigerant valve, DX Unit, etc.
