ACES2 Location
You will need to consider the best location of the ACES2 unit to get all the connectivity options.
The ACES2 unit will need:
- Internet access via rj45
- An earthing point for the shielded cable
- Wall socket (100-240V) for power point
- 2 wire cable for each evaporator temperature sensor or thermostat to take control.
- 4 Wire screened cable for the temperature probe.
Normally we see partners installing the ACES2 unit near the Eniscope (So they can share the same
network access point and use the Eniscope earth point).
Temperature Probe Location
You need to decide the best locations for the temperature probe(s) and quantity needed, we
recommend 1 per Aircon unit or at least 1 per 5m2 floor area.
Obviously, you need to use your onsite observation for the best positions, but we recommend the
sensor being place in the middle of the area/room being covered and near the ceiling. If you have 1
sensor per aircon unit, then again position as such that it is near the aircon but away from the walls,
corners or obstructions.
Other considerations of places not to put the temperature sensor include:
- In direct flow path of aircon unit (remember we want the average room temperature, not the
evaporator air temperature like ACES1 use to).
- In the direct path of any fans installed on site.
- Above the ceiling tiles or ceiling of a room.
- Next to lights or heat sources.
- Keep away from doorways or windows (where you have temperature variation both sides).
- Keep the sensor out of direct sunlight.
- Touching metals, etc that could be hot or cold.
