Commissioning Tips for Optimum ESP Ultima PerformanceStarting the ActronAir System:First, ensure that your ductwork installation is fully completed before performing air balancing and the self learn fan setup.1. Turn the mains Power-ON at circuit breaker.2. Set the Wall Control to HI Fan only.NOTES• This will automatically open all zones, if zones and Zone Controls are installed.• The Zone Controls will automatically display FAN and all zone damper indicators will indicate fully open bladepositions.• Step 2 above can be done from any LM-Series master Wall Controls.3. At this time, perform air balancing to ensure the correct amount of air flow is coming out from each supply airdiffuser. This is to ensure that when the system is on ESP Fan and when you minimise the zones, the outlets arebalanced to provide the correct amount of air and will not be noisy.NOTEGetting step 3 correct is important to the system’s performance.Good air balance is the contributing factor to a good ESP Ultima system. Once the air balance is correct, theperformance improvement can be quite significant, as you have now guaranteed the set up is the way as themanufacturer has intended. Seek advice from ActronAir installation guidelines for recommendations on grille sizes,ductwork and static pressure.Starting the Compressor:1.
