Alarm description and generation/reset conditions

indication

 

 

Regular communication error between hydro unit and remote controller (system controller) If there is no

E03

regular communication from the remote controller for three minutes, the hydro unit regards it as no

remote controller. If there is no communication from both sides, alarm E03 occurs. Auto-reset: When

 

 

successful regular communication is made

 

Regular communication error between hydro unit and outdoor unit When serial signal from the outdoor

 

unit cannot be received though normal serial signal is sent to the outdoor unit 1) When serial signal

E04

cannot be received continuously for 60 seconds (S code communication) 2) Communication is still not

successful for 80 seconds through three retries if serial signal cannot be received for 20 seconds after

 

new communication (f code) starts When the remote controller starts operation, serial transmission

 

starts with the new communication format. Auto-reset: When successful regular communication is

 

made

 

Condensing temperature TC sensor defect

F03

If short-circuit or open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Hydraulic heat exchanger inlet temperature TWI sensor defect

F10

If short-circuit or open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Hydraulic heat exchanger outlet temperature TWO sensor defect

F11

If short-circuit or open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Hot water cylinder temperature TTW sensor defect

F14

If short-circuit or open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Floor inlet temperature TFI sensor defect

F17

If short-circuit or open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Internal heater outlet temperature TWO sensor defect

F18

If short-circuit or open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Low-pressure sensor defect

F23

If open-circuit state continues for two seconds, an alarm occurs.

 

Auto-reset: When normal value is confirmed

 

Hydraulic heat exchanger EEPROM defect

F29

One mismatch is detected if there is no verification ACK after data write to the EEPROM Reset

condition: This alarm is inhibited while the unit is not working.

 

 

(When EEPROM1K is mounted, this alarm cannot be reset.)

F20

Floor inlet temperature TFI sensor disconnection or wrong installation (This alarm is reset by stopping

operation and is checked again.)

 

F30

Onboard expansion IC defect This alarm is not reset automatically.

 

 

 

Group line in an hydro unit

 

This alarm is checked during initial communication immediately after power-on. This alarm occurs

L07

immediately after operation start.

 

This alarm is not reset automatically. (This alarm is inhibited while the unit is not working, but occurs

 

again after the unit operates.)

L09

Hydro unit capacity has not been set.

This alarm is checked immediately after power-on. This alarm is not reset automatically. (This alarm is

 

inhibited while the unit is not working, but occurs again after the unit operates.)

A01

Pump defect or abnormal flow rate This alarm is not reset automatically.

 

 

A02

Excessive water temperature increase by the heating heater Auto-reset:

 

 

A03

Excessive water temperature increase in the hot water cylinder

 

 

A04

Freezing is detected. Auto-reset:

 

 

A07

High-pressure switch malfunction This alarm is not reset automatically.

 

 

A08

Low-pressure sensor malfunction This alarm is not reset automatically.
