Q. Can I use 2 Zone Sensors to average a large room?
A. No, for averaging large rooms you must use a 1 x Zone Control and 1 x Zone Sensor.
Note:
Use of 2 Zone Sensors causes inconsistent temperature sensor readings.
Q. Can the Wall Control show the room temperature as main display instead of setpoint?
A. No, the setpoint is always on display to prevent any confusion in the temperature setting. To view the current room
temperature, press either the
or
buttons. The room temperature will be displayed for 3 seconds with the

flashing for 3 seconds then revert back to setpoint display.
Q. Can the Zone Control show the room temperature as main display instead of setpoint?
A. If you hold the Room Temp button in for 5 secs this display will remain on screen for 45mins then revert back to setpoint
display. Room temp light will flash to indicate you’re in room temperature display.
Q. Does the ESP Ultima 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
Ultima system.
Q. Can I use the master control to control the main area’s temperature?
A. No, the on board sensor on the master control is disregarded when wired to the Ultima system. All temperature information
is fed back from the Zone Controls and or Zone Sensors back to the Ultima module.
Q. Can I check what zone number my Zone Control is from the Zone Control?
A. Yes. When the system is first powered up the zone number is displayed on the Zone Control display. You can also check the
Zone number by holding the
button and pressing the
button. This shows the Zone Number before showing the
software versions.
Q. Can I calibrate the on board temperature sensor on the Zone Control?
A. Yes. Hold in the
button and press the
button and release. The display will first show the zone number, then two
version numbers, then 0.0 (default) This is the calibration adjustment. Adjustments to the negative will make your room
sensor display a lower temperature, and adjustments to the positive will make your room sensor display a higher room
temperature.
Q. How do I calibrate a Room Sensor?
A. While the power is on, remove the Room Sensor by unplugging the RJ45 connection and plug in a Zone Control. Then
hold in the
button and press the
button and release. The display will first show the zone number, then two
version numbers, then 0.0 (default) This is the calibration adjustment. Adjustments to the negative will make your room
sensor display a lower temperature, and adjustments to the positive will make your room sensor display a higher room
temperature. When you’ve calibrated your desired change unplug the Zone Control and plug your Room Sensor back in.
The calibration order is remembered by the Ultima module and applied to that zones room temperature.
Q. Can you adjust the Zone Controls more than 2 degree’s + / - from the master Wall Control?
A. Yes, it is possible via the service menu but not recommended, as you may lose tight temperature control. The default has
been set at 2 degree’s for this reason.
Q. Can you have 2 Zone Controls averaging 1 big zone?
A. No, you must have 1 x Zone Control and 1 x zone sensor for temperature averaging.
