INTRODUCTION
The PL07 from Salus Controls is a modular pump and boiler logic control module,
designed specifically for heating applications.
FEATURES
• Modular installation
• Cage clamp wiring terminals (no terminal screws)
• Separate circulating pump and boiler control relays
• Volt free contacts
• User selectable pump run-on timer
• Auto shutdown in case of power failure

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.
Salus PL07 Manual Ver007.qxd:Layout 1 10/9/10 10:03

OPERATION
Boiler Control
The PL07 will turn the boiler on when it receives a call for heat from any of the
installed thermostats via the KL06 wiring centre. Depending on the jumper
settings the boiler will be turned on immediately, or after a delay of three
minutes. Once the thermostats are no longer calling for heat, the boiler will be
turned off immediately.
The boiler is controlled by the use of a Normally Open (NO) latching relay within
the PL07 logic module. The relay is designed for Volt-free operation, and will
work with boilers with 24V AC or 230V AC control systems.
Circulating Pump Control
The PL07 will turn the circulating pump on when it receives a signal from any of
the installed thermostats via the KL06 wiring centre.
The circulating pump is controlled by the use of a Normally Open (NO) latching
relay within the PL07 logic module. The relay is designed for 230V AC switching.
If within a one week period no switching signal has been detected from the KL06
wiring centre, the PL07 will run the circulating pump for five minutes to avoid
any damage to the pump and boiler.
PL07 INSTRUCTION MANUAL 11
Salus PL07 Manual Ver007.qxd:Layout 1 10/9/10 10:03

PL07 INSTRUCTION MANUAL12
The boiler and pump will be turned on by the PL07 (immediately, or after a delay
of three minutes) if there is a call for heat from any of the installed thermostats.
Once all the thermostats are no longer calling for heat, the boiler will be turned
off immediately and the pump will be operated in accordance with the relevant
jumper settings (i.e. the pump will be turned off immediately, or after a delay of
three minutes).
Safety Protection
In case of power failure to the wiring centre, the PL07 has the capability to detect
this power loss, and will automatically switch the boiler and circulating pump
relays OFF.
Salus PL07 Manual Ver007.qxd:Layout 1 10/9/10 10:03

MAINTENANCE
The PL07 logic module requires no special maintenance. Periodically, the outer
casing can be wiped clean using a dry cloth (please DO NOT use solvents,
polishes, detergents or abrasive cleaners, as these can damage the module).
There are no user serviceable parts within the unit; any servicing or repairs should
only be carried out by Salus Controls or their appointed agents.
Should the PL07 logic module fail to function correctly, check:
• The KL06 wiring centre has mains power.
• The PL07 is inserted correctly into the wiring centre.
• Heating system time switch or programmer is switched on.
