14. Frequently Asked Questions

Q. I cannot adjust my setpoint on my Zone Controller any more than 2
A. 2
is the default setting for master temperature offset. ActronAir recommend this 2
o
control and maximize energy efficiency. Moving this setting +/- 0.2 will result in temperature inaccuracy.
Q. Cooling and Heating seems to take a long time to achieve temperature in ESP fan mode. Am I using the correct
settings?
A. ESP Fan mode really comes into it's own when minimal zones are used. For quicker and more responsive Cooling and
Heating, when using more than minimal zones, select HIGH or CONT HIGH fan speed on Wall Controller. This will
boost heating and cooling and is best optimized when you want to condition more than the minimal zone set up.
Q. Cooling and Heating is not sufficient in my zone.
A. Air balancing is essential part of system commissioning in ESP Ultima system. The duct design may be prohibiting the
correct amount of airflow reaching your area. Please contact your installer to ensure air balancing has been carried out.
Q. There is substantial air noise coming from my outlet.
A. If the outlet gets too noisy when the unit or zone is first turned on, the system maybe over supplying airflow to your
area. Ensure ESP Fan mode is selected when minimal zones are used.
Q. There are dashes across my control display.
A. Make sure you have not had a power interruption. If this is still present on the display after 20 seconds, please contact
your installer. Incorrect wiring or a broken circuit could also cause these symptoms.
FAULT CODES:
When E? is displayed in the Wall Controller or Zone Controller, take note of the digits after E and contact your installer.
E3 - System has detected less than 2 sensors (Ultima requires at least 2 sensors in circuit) or, a remote sensor is short
circuit.
E5 - No Communication. The system is constantly relaying information back and forth. This indicates the communication
is not happening. Contact your installer to check your wiring and cable's integrity.
