Waterco Aquamaster
I pg 07
Outdoor Installation
The LCD Panel is able to be mounted outdoors within a suitably rated weatherproof enclosure.
c. Temperature Sensors
The Aquamaster has a number of sensors for pool, roof and air temperature monitoring.
Pool Sensor:
a) The pool water temperature sensor should be installed prior to any heater or solar and will
display either the pool or the spa temperature, depending on the current operation of the pool.
b) Immediately after the filter drill a 9.5mm hole in the side of the line as shown in the image below.
Insert the special plug into the hole and rotate home.
c) Insert the sensor holder by pushing into the plug fully up to the head. This is a tight fit to ensure
sealing. Lubricate with soap if necessary but do not use mineral oil or grease.
d) Strap lead firmly to pipe to prevent any strain on the sensor holder or lead entry.
e) The sensor should not be installed on top of any pipe work coming from the pump as it is
exposed to sunlight and accidental physical damage may occur. It should be installed on an
inside elbow of the pipe work (as shown). This will eliminate heating of the sensor by sunlight –
giving inaccurate readings, and also minimise the risk of damaging the sensor by pool users.
Pool Sensor Installation
Incorrect Position
Correct Position
Roof Sensor (required if a solar heating system is installed):
a) If the sensor lead is to be concealed, e.g. underground, make sure it is run through a conduit to
ensure easy removal if service is required.
b) To take cable to the roof it should be tied off neatly with electrician’s cable ties to one of the solar
pipes.
c) The roof sensor is supplied housed in a probe holder. This holder should be fixed to the roof in
a small pad of adhesive the same angle as the solar absorber. This is to ensure the sensor will
measure the actual roof temperature and the reading will be unaffected by the cooler pool water
when the solar system turns on.
d) The sensor must always be located so it is in the sun at the same time as the solar absorber
array; otherwise incorrect readings will be made. This can happen when parts of the absorber
are in the shade, and the sensor is still receiving full sunlight.
e) The sensor should be located at least 600mm from the top of the roof to eliminate any wind chill
factor, 1m from the sides of the roof, and at least 500mm from the solar absorber array to read
a constant accurate roof temperature.
Keep the adhesive clear of the cable and also from the top of the holder to facilitate the removal
of the probe holder if it should require future service. Suitably clip the lead along its run, to prevent
any strain to the sensor holder.
