Important Notes

Congratulations on purchasing the PoolSmart Plus touchscreen heating
controller, manufactured in England to the highest standards.

To ensure your new product will give years of trouble free service please

carefully read the following instructions.

Incorrect installation will aect your warranty. Do not discard this

manual, please retain for future reference.

Product Overview

Installation

Screw mount the PoolSmart Plus to a suitable wall in a dry weather proof
location out of direct sunlight, ensuring that it is sited no more than 3
metres from the swimming pool ltration pipe work and upstream i.e:
before the heating appliance.

ENGLISH

The rear face of the PoolSmart Plus has an upper key hole screw
hook, located at the rear of the enclosure, and 2 lower screw holes
which are accessed after removing the 4 screws retaining the lower
access cover at the front.

ENGLISH

T-Piece Installation

The T-Piece should be cut into the swimming pool ltration pipe work
upstream (i.e. before) the heating appliance using a suitable ABS cement.

The T-Piece has 63-mm female sockets and is supplied with:

• 50-mm reducers (Model PSPC-50)

• 1½” reducers (Model PSPC-1.5)

NOTE: Correct orientation of the T-Piece is essential to enable the correct
operation of the ow switch and temperature detection probe i.e. the
arrow moulded into the T-Piece must point in the direction of ow.

Electrical Connection

The PoolSmart Plus must be installed in accordance with the Country /
regional requirements and regulations. In any event the work must be
carried out by a qualied electrician who will provide a certicate of
conformity upon completion of the work.

Undo the lower cover screws and remove the electrical access cover.
All electrical connections should be made into the relevant terminal block
position, according to the labelled positions.

Connection Explanation:

Terminal 1 = Incoming Live 100 to 230V
Terminal 2 = Incoming Neutral
Terminals 3 and 4 = Priority of Heating ltration pump override signal out
Terminals 5 and 6 = Heat Out – Volt free switched output to control heating
appliance (2-Amp MAX if the load is greater than 2-Amp an auxiliary
contactor must be used)
Terminals 7, 8 and 9 = RS485 MODBUS Data Link
Terminals 10 and 11 = Flow Switch
Terminals 12 and 13 = NTC Temperature sensing probe

The actual pool water temperature is shown in the upper area of the dis­play. The required temperature is shown in the lower area of the display.
The required water temperature can be adjusted by touching the ‘UP /
DOWN’ touch button keys until the required temperature is displayed,
adjustments are in 0.1°C increments.

Priority of Heating is a function that ensures your pool water is constantly
maintained at your required temperature. When Priority of Heating is
activated the Symbol will be displayed on the screen.

The controller will then monitor the pool water temperature, and start
both the pool circulation pump and heating process when necessary.

Operating Instructions

On initial power up of the controller the digital display will be illuminated.

The heating device will only be switched ‘On’ when the following criteria
are met i.e:

• Water circulating pump is ‘On’ delivering in excess of 4,000 litres per hour
(4m³/h)

• The required temperature is set to a higher value than the actual water
temperature.

Time Switching Delay

To prevent overheating of the switch components within the heating
device caused by frequent on/ o switching (cycling) the controller has
been pre-programmed with a time delay function.

When time switching delay is activated the message display will show
‘HEATER DELAY’ for 2 minutes.

Dierential

When the pool water has reached the required temperature the
heating device will switch o and will not switch back on until the water
temperature has fallen 0.6°C below the require temperature.

Operating Modes

There are ve operating modes:

The required Modes are selected
by touching the ‘M’ button
key, each touch causes the mode
to change to the next mode. The
display will indicate which mode
is currently selected together
with the clock time.

reached the controller will switch the heating appliance o, followed by
the ltration pump.

After one hour a new water temperature sample will be taken, if the
sampled water is at or above the required temperature no heating will
take place and the controller will switch the circulation pump o, then one
hour later take a new temperature sample.

The sequence will continue to repeat until ‘Priority of Heating’ is switched
o.

In this mode the controller will heat whenever it is receiving ow during
a timed on period and ‘Priority of Heating’ will take place whenever the
timer is ‘OFF’.

Trouble shooting

Heating Device will not switch on

In most cases this will be the result of one of the following not being met:

Possible Cause 1.) The required temperature has been reached.
To conrm the controller is requesting the heating device to switch on check
that the required temperature is at least 0.6⁰C greater than the current water
temperature and that the red thermometer in the display is ‘animated’ showing
the thermometer increasing

Possible Cause 2.) Insucient Flow.
The display will show ‘NO FLOW’ if the ow switch has detected that the ow
volume is below 4,000-litres per hour (4m³/h).
Check that the ow volume is greater than 4,000-litres per hour and that the
ow switch is in the correct orientation to sense ow (i.e. check that the arrow
moulded into the ow switch body is facing in the same direction as the ow
travelling through the T-Piece).

Possible Cause 3.) The controller is in a timed o period.
Check if the controller has the ‘TIMER’ symbol displayed – if it does check
your clock and time period settings (explained in the set up section).

Possible Cause 4.) The heat output has not been correctly connected to the
control circuit of your heating device.
Check the wiring diagram for verication on how the controller should be con­nected to the heating device and seek the expertise of a qualied electrician if
in any doubt.

Possible Cause 5.) The controller is in time delay mode.
If the display is showing ‘HEATER DELAY’ the controller is in time delay mode.

This is activated if the controller is requesting the heating device to switch on
more than once in a 2-minute period – this can be caused by a uctuating ow
rate (just above and then just below the 4,000-litre per hour requirement) or
uctuations in water temperature.

To rectify check the plumbing for any restrictions to ow and increase the ow
volume through the T-Piece. Also check the positioning of the temperature
sensor, it should be positioned before the heating appliance.
