Hey guys, would you have a wiring diagram for two boards *I'm at a unit, a Hi-Velocity HV-100BU AHU indoor with a RZQ140B8W1B outdoor. Complaint it won't heat but I can't get the condenser to run. Only details I see are FBQ35-60B7V1 and an EC9509D. Any ideas? Calling for full heat but the condenser just sits there.

Has the RZQ unit had the software updated? B series had poor inverter/fan control.

I've installed and serviced/repaired lots of Daikin but can't understand your setup?

Hi-Velocity HV-100BU AHU...not familiar with this

with a RZQ140B8W1B outdoor...not sure how you can pair this with the AHU?

FBQ35-60B7V1 and an EC9509D...this doesn't make any sense?

Do you have different model numbers so far away from those in England?

Doubt it, it was our 1st time on site today and the unit looks like it hasn't been serviced in a good good while.

It's a Daikin condenser used as a heat pump to a coil on an AHU. The controllers are April Air, AHU is Hi-Velocity. It's the strangest set up I've ever seen. They're both wired into a panel with 2 Daikin boards. The 2 codes are the only info I can see on the boards.

I've seen these set ups before, condenser feeding the ahu coil using the pcb control board from a daikin unit, sort of worked.

That's the ERQ model condenser and AHU controller

Its a board from a ducted unit i think, hi velocity units, bunch of them installed here, quare ****e. First check you have correct voltage at outdoor, and that neutral is properly connected. Indoor stat feeds to board to call outdoor, can you hook a standard daikin controller to the indoor board and test run unit?
