COMMISSIONING
Check:
1. Air-flow Vs Damper
a. Test B.Nom100% :
COMMISSIONING
i. adjust the blower speed % (3333) to get the required air-flow
ii. adjust the exhaust speed % (3864) to get the required air-flow
b. Test B.Nom0%:
i. adjust the damper compensation (3335) to maintain the required air-flow even with damper fully closed
ii. adjust the damper compensation (3366) to maintain the required air-flow even with damper fully closed
2. Filter safety thresholds
a. Test B.Nom100% and Test B.Nom0% : read filter ΔP (3442) and adjust the bigger measure multiplied by 2.5 at threshold 3345
3. Frigorific circuit tests
a. Cooling mode
i. Test C---Cool: (if variable speed compressor option, set speed value)
1. Check circuit pressures and temperatures
2. Check electrical consumptions
b. Heating mode
i. Test C---Heat: (if variable speed compressor option, set speed value)
1. Check circuit pressures and temperatures
2. Check electrical consumptions
4. Unit option tests
a. Electrical Auxiliary heaters (Test H1-1 Full)
i. Check supply temperature

5. Advanced regulation optimization
a. Compressor ΔT
i. Cooling.
1. Test C1c1 Cool: read │Mix-Supply| temp and adjust compressor stage ΔT at menu 3434
ii. Heating.
1. Test C1c1 Heat: read │Mix-Supply| temp and adjust compressor stage ΔT at menu 3444
b. Auxiliary Heaters ΔT (Gas burner or electrical)
i. Heating.
1. Test H1-1: read │Mix-Supply| temp and adjust heaters stage ΔT at menu 3734
c. Staging sequence (compressor/electrical/water/burners)
i. Aux Heaters Priority 3731= Never/ Always /OutTemp
ii. Pre Heaters Priority 3736= First/Last
d. Dynamic setpoint
i. 3225= ΔT between customer set point and outdoor temperature
e. Fine temperature control
i. Smooth 3231= No/ DeadZone/Comfort
6. Leak Detection
a. Cooling
i. Test C1--Cool: read Subcooling and adjust 3437
ii. Test C2--Cool: read Subcooling and adjust 3438
b. Heating
i. Test C1--Heat: read Subcooling and adjust 3447
ii. Test C2--Heat: read Subcooling and adjust 3448
Once all the settings have been adjusted, the list of parameters must be downloaded (Wizard tool), stored and signed by the customer.

WARNING! During the settings, wait
until the economizer is fully closed
or opened, since it takes 1-2 minutes
to switch.
