VRVII FXFQ cassette cooling offset

[Paul84]

Hi guys,

I've got a large VRVII system with 140 ID units on a Dbac - 6yrs old. We were called in due to temperature fluctuations on all cassettes due to stratification on suction air senses - resulting in units switching from heating to cooling.

Where possible I've set FXMQ-M codes 10-2-03 and 10-5-02 the rest require remote sensors (or later model pcbs).

But the FXFQ-M have a temperature offset in cooling by 2*C. Evident when checking the 41-01 sensor when changing modes. This is preventing me from fitting remote sensors.

Is there a field code that will allow me to set the offset to 0*C or do we have to replace the pcb with a new one. Obviously i cant set 10-2-01 and 50-4-01 as this will affect the reference point for the Dbac. I've also set 12-2-02 and 12-4-03.

Look forward to hearing your answers as i looked everywhere.

Paul

sent you install manual - got setting codes for fxfqm
you can also change the airflow level to upper to prevent cold draughts
