INSTALLATION
Please read the important safety information at the start of this manual before
you begin to install the device.
NOTE: All electrical installation work should be carried out by a suitably
qualified Electrician or other competent person.
If you are not sure how to install this logic module consult either with a qualified
electrician, heating engineer or your boiler / heating system supplier for advice
on how to continue.
The PL07 logic module is not a standalone unit, and is intended to be mounted
on a KL06 wiring centre. The wiring centre should be installed first, followed by
the PL07 logic module.
To install the logic module, undo the securing screw on the wiring centre, insert
the logic module and then refit and tighten the securing screw.
The PL07 logic module should be mounted in a location where it will not come
into contact with water, moisture or condensation. The location should also be
accessible for the connection of mains and control wiring.

There are few electrical connections
required to the PL07, and these
connections should be made to the
cage clamp terminals on the front of
the module (after first securing the
cable in the KL06 wiring centre):

CABLE CONNECTIONS
The PL07 does not use conventional screw terminals for wiring connections, but
uses cage clamp terminals. The cage clamp terminals are spring loaded and
provide a very quick and secure method of making all the electrical connections
to the module.
Please take the following steps to make the wiring connections to the PL07:
1. Prepare the cable ends:
• Strip outer sheath to a distance
of 110mm
• Strip 10mm from the ends of
each conductor sheath
It is very important that these
dimensions are followed to ensure
correct connection to the module.
2. Insert the cable into the cable grip:
3. Route the conductors through the wire guides:

4. Insert the conductors into their appropriate terminals:
Cable sizes used should be within the following ranges –
• Solid: 0.5 – 1.5mm2
• Stranded: 1.0 – 1.5mm2
If using stranded cable, a small screwdriver can be used
to open the cage clamp to allow conductor insertion.
5. Fit the protective cover:
Secure the cover by turning the locking screws a quarter turn.
ELECTRICAL SAFETY - The PL07 logic module should not
be operated without the protective cover in place.

USER INTERFACE AND CONTROLS
The status and operation of the PL07 is clearly shown by the use of two green
Light Emitting Diodes (LEDs) on the module front panel:
When initially powering up the PL07, both LEDs will turn on for about one second
before turning off.
The LED indicators allow the user to see at a glance the current status of the logic
module. The only user adjustable settings for the PL07 are the mode jumper
settings, accessible from the front panel of the module:

JUMPER SETTING SUMMARY
Jumper Function Default Setting
J1 – Boiler and Pump Jumper in ON position
protection ON – OFF
OFF – Disables boiler
and pump protection
(immediately turns pump
and boiler relays on when a
thermostat calls for heat).
ON – Enables boiler and
pump protection (delays
turning on pump and boiler
relays for 3 minutes when
a thermostat calls for heat).
J2 – Pump overrun Jumper in ON (3
time ON – OFF minute) position
ON – After all thermostats
have switched off the pump
runs for an additional 3
minutes for boiler protection.
OFF – Disables pump over run.
When all thermostats are
switched off the pump will also
switch off immediately as well.
