Operation
Turn on all the Heaters with their Pool Tempera
ture Controls.
The Master will show temperatures and the Slaves
“---”.
Set the required temperature on the Master and
provided there is an electrical demand at the
Master’s Pool Demand connection, the Heaters
will run.
Features
A Master is the only Heater with a Pool Sensor
connected, move the sensor and the Master
moves.
If the Master Pool Temperature Control is
turned off, none of the Heaters will run.
If a Slave’s Pool Temperature Control is turned
off it will not operate. The Master will know and
alter its control accordingly.

Turn on the Mains, then switch on all the
Heaters. After a short self-test the Master
should show the actual temperature, and the
Slaves three dashes “---”. If a Slave continues
to show a moving display of dashes this indi
cates it not correctly connected to the Master,
check the Interconnection cable plugs are fully
home.
Replace the panels.

Pool Temp Sensor wires
If a safety device on the Master operates it will
not run but will continue to control the Slaves.
If the Master Control fails the ‘system’ will fail.
Change the Master to a Slave and one of the
Slaves to a master to enable the system to run
again.
If a safety device on any of the Slaves operates
that Slave will not operate.
If a Slave has Flow fault which its Pressure
Switch detects the burner will stop immediately
and the Yellow LED will light. It will no longer be
available to the group. It will then check every 3
minutes or so to see if the problem has been
corrected, the Yellow LED will flash. It will put
itself back in the group if flow is satisfactory.
The Master display can be altered in Setup
Mode like a single Heater. (see Page 16)
Unlike a single Heater, there is no modulation
of individual burners.
Displays
The Master display is just like a single Heater.
A Slave will display “---” when working as part of
the group. It will show all the fault conditions of a
single Heater except “P/oc”, the Pool Sensor
Open Circuit fault. If this is displayed it indicates
a interconnection problem, check the cables and
connectors.
The Pool Demand LEDs work as a Single Heater.
On when running, Off when off, and Flashing if
not needed by the Master.
The warning LEDs work for all in a group, as per
a single Heater.
