Daikin Altherma LT Controller Query

[waltsalt]

Hello all,

I've a quick query about my Daikin Altherma controller. I've gone through my manual from front to back and spent the last two days searching on the internet but can't seem to find any answers.

The pump icon and the heating icon are constantly flashing on my controller unit when the controller is turned off. The two icons are flashing simultaneously. There doesn't seem to be any fault as such because the heating still works when it comes on through the night (running on E7 at the moment rather than 24/7 now we've got some balmy mid-February conditions).

I'm just wondering if the blinking icons are anything to worry about. The heat pump has been in for just under a year and the icons have only started blinking recently.

The heat pump model number is EBHQ008BBV3 and the controller model number is ARC448A4.

I appreciate help from anybody who may have come across this.

Cheers.
