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
changes.
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.
If a safety device on the Master operates it will
not run but will continue to control the Slaves.
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 Filter 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 Filter 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 con
nectors.
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.
