I have 5 x VKM50GBV1 HRV units with DX coils connected to a VRV 4 2 pipe system
there are no remotes fitted and the system is wired to an I Touch
none of the units are connected to a fan coil the HRV settings are enabled
the mode settings have been changed for centralised control 17-7-02
the I Touch sees the units and appears to turn them on but the units are not running
the ventilation, freshen up and air volume have been enabled
any ideas, thanks in advance

hi install monkey

all of the HRVs have been addressed and the I Touch can see them
it appears that the I touch switches them on and off but when checking the HRVs are just sitting there not running

check each hrv unit- check for t1 t2 terminals- on the same block as the np (remote controller) and the f1f2 (transmission), also check theres power to each indoor (240v)

I have checked and rechecked the wiring and its all ok
not sure what you mean by the dots but the units show up red on the I Touch
if you mean dots like you would have to show that the filter need cleaning (timer)
there are none showing
If I fit remotes the units start up and run
the I Touch is a C series the one with the pen on top
there's power to all units and the unit count is correct on the outdoor unit

hi install monkey

rechecked all wiring all good and checked the I Touch there are no lil dots
was wondering if there were any mode changes that I need to make
