Temperature Sensors. Waterco aquamaster

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

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.

Correct Sensor Position

Incorrect Sensor Position

Sensor orientation on curved tiles (front view)

Sensor should be pointing up the roof and secure with silicone on the plastic body only

Sensor orientation

(side view)

The sensor should be orientated such that it lies on the crest of the roof tiles and not in the troughs.

This eliminates water being trapped in the silicon glue that holds the sensor in place, and giving erroneous readings. The roof sensor should also be positioned so that it points up the roof tiles (as shown above).

Air Sensor

Mount the air sensor outdoors and out of direct sunlight.

d. Valve Actuators

The Aquamaster system is optimized to operate Waterco FPI valve actuators and should be installed in consultation with the product installation and operating instructions.

e. Flocheck Valve (optional)

Waterco Aquamaster

I pg 09

Waterco recommend the Aquamaster system is fitted with the optional Waterco Flocheck valve and should be installed in consultation with the product installation and operating instructions.

FUNCTIONS

The Waterco Flocheck valve has a number of essential functions:

1. As a normal pre-loaded check valve to prevent pool water backwashing the filter on shutoff or drain down.

2. As a pump protection device for when there is no filter water flow. Power is switched off by the solar controller through integration with the Flocheck valve, stopping the pump immediately.

3. As a warning device to highlight the water flow below recommended levels for solar pool system operation.

4. As an adjustable flow switch which can be tailored to the customer’s requirements.
