20. Commissioning Tips for Optimum ESP Ultima Performance
Starting the ActronAir System:
First, ensure that your ductwork installation is fully completed before performing air balancing and the self learn fan set
up.
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 blade
positions.
• 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 air
diffuser. This is to ensure that when the system is on ESP Fan and when you minimise the zones, the outlets are
balanced to provide the correct amount of air and will not be noisy.
NOTE
Getting 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, the
performance improvement can be quite significant, as you have now guaranteed the set up is the way as the
manufacturer has intended. Seek advice from ActronAir installation guidelines for recommendations on grille sizes,
ductwork and static pressure.
Starting the Compressor:
1. Ensure proper evacuation procedures have been followed on interconnecting pipe work before opening the
refrigerant ball valves.
2. Make sure the refrigerant gauges are fitted before starting compressor commissioning.
3. Set the Wall Control into COOLING or HEATING MODE.
4. Allow approximately 10 minutes for the system to stabilise coil temperatures before adding additional refrigerant
for additional pipe work outside of the pre-charged lengths. (See Pipe Length section for further details).
21. Frequently Asked Questions - ESP Ultima System
Q. Does the back light on the individual zone control effect brightness of the room at night?
A. No. The display back light turns off at approximately 30 seconds after any button is pressed.
Q. Can you turn the system off from the individual zone controls?
A. No, It can only be done from the master control. If you are the last zone on and you turn it off, zone 1 will automatically
turn on. The unit will then run based on this zone’s cooling / heating demand. This is due to the last zone safety feature
default setting.
Q. Can you adjust differentials on the zone?
A. No you cannot.
Q. Is there any indication on the zone control when it is in defrost mode?
A. No. The HEAT indicator flashing on the master control indicates and highlights this.
