ON THIS SYNOPTIC DISPLAY, IN “READ BUS VALUES”:
Remarks
Check if supply Qsf and extract Qex are balanced
Outside
Inside
Exhaust
Teav
Tsan
Tean
Tsav
Supply
Check T° are all compliant with the heat exchanger efficiency
µsupply = ((Tsan-Tean))/((Teav-Tean) (must be 0,93 +/-20% for DXA and 0,84 +/-20%
for DXR)
µexhaust = ((Teav-Tsav))/((Teav-Tean) (must be 0,93 +/-20% for DXA and 0,84 +/-20%
for DXR)
Check T° are compliant with the inside and outside T° (ductwork insulation)
Teav must be equal to inside T°+/- 2°C
Tean must be equal to outside T° +/- 2°C
Check the 2 fan motors speed are compliant with relevant airflows (see on
curves)
If measurement is in the bad area, check the pressure drops on the network (especially
grilles, air inlets, length / shape of the pipes and no bottleneck in the pipes).
Check pressure in the compensation valve is compliant with the pressure set
point (-60PA, -80Pa, -100Pa or -120Pa)
Check that Pex is the right value you’ve chosen for automatic mode.
