Wall Mount Temperature/Humidity Sensor
If your dehumidifier was ordered with a wall-mount humidity and temperature sensor, mount the
sensor about five feet above the pool deck on an interior wall with natural air circulation. Avoid
the following locations:
• Hot spots near concealed heating pipes, warm air ducts, supply register outlets, or solar
radiation.
• Cold spots due to a cold wall or drafts from stairwells, doors, windows, or supply
register outlets.
• Dead spots such as behind doors or in corners where room air cannot circulate freely.
A supply air temperature sensor and duct holder is also provided to be installed
downstream of any field provided heaters. Mount this in the supply duct and seal the
penetration. Install at least 5 ft. downstream of all heaters and not in the “line of sight” of the
heater elements as the radiant heat produced by the heater may affect the reading.
2.8.2 Water Temperature Sensor
Desert Aire dehumidifiers ordered with the pool water heating option are supplied with a water
temperature sensor and an aqua stat well.
• Screw the well into an adapter fitted into the pool water piping. The well is equipped with
a 1/2” MPT connection.
• Install the sensor upstream from the dehumidifier such that the inlet water temperature
is sensed. The Aux pool water heater should not be installed upstream of the
dehumidifier. Install heater downstream or in parallel with dehumidifier.
• The sensor must be installed in a location where it will accurately sense the
pool water temperature. This means you must have continuous water flow at
the sensor location.
2.8.3 Installation of Sensors for the SelectAire™ with Integral Exhaust Fan
In pool applications, it is critical to maintain negative space pressurization relative to adjacent
spaces and the outside ambient. This prevents moisture laden air from being driven into the wall
cavities and condensing. The SelectAire™ unit includes provisions to measure the differential in
static pressure between the space and the outdoors and helps to maintain this negative static
pressure in the space.
2.8.3.1 Indoor Static Sensor Installation
The indoor static pressure sensor should be mounted in a location not subject to
damage from occupants. Place the sensor as far as practical from doors, grilles, and
operable windows that may cause pressure fluctuations. Locate a minimum of 3’ above
the floor level in the pool area. Note that in rooms with extremely high ceilings (greater
than 30’) it is preferable to locate the sensor a minimum of halfway up the wall. This is
due to building stack effect where the pressure may become higher at the ceiling than
at the floor.
