Hello
Lookin for advice and/or info where i can find the correct manual or info.
Indoor unit: Rotex HPSU 308 with electrical backup heater
Outdoor unit: RRLQ008CAV3

Devices are second hand purchase. Seller told that it has worked with out problem.
Electrical and hydraulic installation are made by professionals and checked many times. Indoor unit works right, we quess. Water/heating lines warm-up by backup heater.
HPSU unit trying start outdoor unit. Pump-logo flash in multifunction display. Some times pump-logo stays few second without flashing. Outdoor unit fan start rotate.
After few second pump-logo disappears in display and outdoor unit fan stop.
No error messages.

On Circuit board PCB3 (service monitoring board) in outdoor unit green led flashing. 2 of 4 red led lights are ON.
Can't find anywhere what those led light monitoring. Do they tell something for issues?
Also PCB3 board has several dip-switch and push-bottoms. Looking for info what they are and which positions are correct?

Any ideas how to solve where is the problem and why outdoor unit won't stay running?
Also interesting find out what does PCB3 service leds indicate.
