Q. Can I calibrate the on board temperature sensor on the Zone Control?
A. Yes, Hold in the Room temp button and press the ON/OFF 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 Room temp button and press the ON/OFF 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 have 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.
Q. Do I have to assign zones or sensor to zones on commissioning?
A. No need, when the system is initially powered up the Ultima system will automatically acquire the utilized zones.
Because each zone has its sensor there is no need to assign sensor’s either.
Q. If I am not in ESP mode on the master will my zone still modulate the airflow?
A. Yes, it doesn’t matter what fan mode your in, if your zone control is in ESP Auto mode (ON) the zone will modulate to
control your conditions.
Q. Where would we put common zones if we wanted to use one?
A. You no longer need wasteful common zones with Ultima. 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. Ultima 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 FAN button on the Wall Control and set fan to HIGH speed.
Q. How can I make the System run at a constant 100% capacity (for example when re-charging the system?
A. In Cooling Mode: Adjust the master wall control set temperature 4°°C lower than the room temperature and set the
indoor fan speed to high with all zones open.
In Heating Mode: Adjust the master wall control set temperature 4°°C higher than the room temperature and set the
indoor fan speed to high with all zones open.
