3.13 MULTIPLE HEATER KIT
Adapter PCB

Overview
It is possible to connect together several heaters
into a group cascade system and by doing so obtain
a larger output with an economical and a fail-safe
design. The multiple heater kit enables between two
and six heaters to be connected together to auto-
matically load share as part of a group.
This works by one heater being a master and the
others being slaves. The master is set for the re-
quired pool temperature and it then controls as many
of the heaters as necessary to obtain the tempera-
ture. It also equalises the operating time of every
heater so they all do the same amount of work. If
there is a mix of heater models, the Genie Dual
should be the master.

Installation Instructions
•
Disconnect the heater from the mains then re-
move the top panel and the electrical chassis
cover.
•
Remove pool thermostat control knob
•
Remove pool thermostat PCB by removing the
retaining plate and carefully slide out until fully
accessible.
(Fig. 10.0)
•
Carefully fi t the adapter kit PCB in the space
behind the pool temp display on the PCB (
Fig.
10.0)
ensuring that the six pins on the PCB pass
through the underside of the adapter PCB and,
that the plastic locking pillars snap into place.
Refi t pool thermostat PCB and knob.
•
Repeat the above steps for all the heaters.
•
Using the supplied cables, pass them through
the upper rear panel grommet and daisy chain
the heater adapter PCBs together. The fi rst and
last heater in the ‘chain’ will use the termina-
tor plugs to fi ll their 2 unused sockets. There
are 2 diff erent coloured terminators, they can
be placed in either the fi rst or last heater in
the group. NB. ensure the connectors are fully
inserted
(Fig. 10.1)
•
Choose which heater is to be the master and
when make the rest slaves by disconnecting
their pool temperature sensors. Remove the
leads to the pool temperature sensor from the six
way terminal strip on the electrical chassis and
tie back in a safe place.
(Fig. 10.2)
•
Any external electrical control should only be
connected to the Master, pool demand. Remove
any pool demand links from the slaves.
