Trigger Effect Reset
Main PCB A1P detects incorrect type
interface. Unit will stop operating. Automatic reset (when correct type user
interface is detected).
Possible cause Check Corrective action
Incorrect type user interface. Confirm used user interface is listed in
option list. Replace user interface to type listed in
option list.
Incorrect combination of user interface. Confirm compatibility between types of
user interface. Replace user interface(s) to type listed in
option list.
Faulty user interface. Check user interface. Replace user interface when required.
Faulty main PCB. Check if the main PCB receives power.
Check if the HAP LED is blinking in regu-
lar intervals.
Check if the correct spare part is installed.
Check the wiring to main PCB.
Check voltage P1P2 ±16 VDC. Adjust power to the main PCB.
Replace main PCB when HAP LED is not
blinking in regular intervals.
Install correct spare part or update main
PCB.
Adjust wiring to main PCB when required.
External factor (e.g. electrical noise) (error
disappears after power reset, but returns
after a while). Check for source which could cause elec-
trical interference. Avoid electrical interference.
Trigger Effect Reset
Main PCB A1P detects multiple HRV units
are set same group number in same F1F2
bus. Unit keeps operating (only warning). Power reset (if no more duplication of
group numbers in same F1F2 bus).
Possible cause Check Corrective action
Multiple HRV units on the same F1F2 bus
are set same group number. Check the group number by the user inter-
face on the units indicating UC caution on
the central control device. Change the group number(s) to have only
unique group numbers.
Faulty user interface. Check user interface. Replace user interface when required.
Faulty main PCB. Check if the main PCB receives power.
Check if the HAP LED is blinking in regu-
lar intervals.
Check if the correct spare part is installed.
Check the wiring to main PCB.
Check voltage P1P2 ±16 VDC. Adjust power to the main PCB.
Replace main PCB when HAP LED is not
blinking in regular intervals.
Install correct spare part or update main
PCB.
Adjust wiring to main PCB when required.
External factor (e.g. electrical noise) (error
