Q. Can I use 2 Remote Sensors to average a large room?
A. No, for averaging large rooms you must use your Wall Controller in-built sensor and 1 x Remote Sensor.
Note:
Use of 2 Remote Sensors causes inconsistent temperature sensor readings.

A. Yes. Hold

Q. Does the ESP Plus system use a different zone barrel to the standard ON/OFF type 24volt Actron Air barrels?
A. No, they are the same barrels. ActronAir designed these zone motors with the intension to communicate with the ESP Plus
system.
Q. Where would we put common zones if we wanted to use one?
A. You no longer need wasteful common zones with ESP Plus. Common zones are impractical, as you have to dump unwanted
excess air from the fan in spaces you don’t necessarily need. Common zones were introduced because of the limitations
of all standard fan coils. ESP Plus is designed to control every zone in your house and eliminate this element of waste and
maximise comfort.
Q. What is the recommended setting for air balancing?
A. For air balancing, press
the
button
on the Wall Control and set fan to
HIGH
speed.
