TLX 7506
RF Digital Room Thermostat
The TLX 7506 is a Radio Controlled Room Thermostat which
requires no wiring and can be fitted in any normal operating
environment within a typical 30 metre range of the TLX 1206
RF Receiver.
The TLX 7506's unique security code is installed into the RF
Receiver as part of the commissioning procedure ensuring
that your RF Receiver will only respond to instructions sent
to it from your TLX 7506 Transmitter. How this is done is
detailed in the Commissioning Instructions later in this guide.

Fixing:
1. The metal mounting plate supplied should be
positioned with a minimum of 70mm clearance to left,
right, above and below to allow adequate airflow.
2. Fix the mounting plate directly to a flat wall using the
wall plugs and screws provided.
3. Remove the battery insulation strip protruding from the

Configuring:
o
The unit is supplied with a 5 C minimum temperature set
point and configured as a heating thermostat as factory
defaults. Two internal links can be used to re-configure
these defaults.
1. Open the unit by slackening the retaining screw on the
lower side and hinge unit upward along the top edge
to separate it from the plastic base. Remove the
batteries.
2. Locate and identify the two option Links 1 and 2. Use
a pair of small wire cutters to carefully cut the
appropriate links to give the required configuration.

Please ensure the RF Receiver (TLX 1206) is wired
for a cooling application (i.e. using contacts 2 and 4).
4. Carefully replace batteries being sure to observe the
correct polarities. Re-fit plastic base and tighten
retaining screw. Check unit is functioning as required
and fit to metal mounting plate on the wall.
Battery Replacement:
This is the only maintenance required for this product.
A 'flashing' battery low symbol will appear at the bottom
left of the display when the batteries start to approach the
end of their life. This indicates that they should be replaced
within the next month. Normal operation will be maintained
during this period. Ultimately the complete display will start
flashing at which time the thermostat will switch off the
heating and shut down until the batteries are replaced.
To replace the batteries the following procedure should be
carried out.
1. Remove the unit from the wall-plate by sliding
upwards and gently pulling away from the wall.
Slacken the retaining screw on the unit and open by
hinging upwards along the top edge.
2. Carefully remove batteries from
compartment and fit two new 'AA' alkaline cells
taking care to observe the correct battery polarities.
Check unit is functioning and re-fit to the plastic base
by hinging downwards from the top edge. Ensure unit
is properly closed and re-tighten the retaining screw.
3. Re-mount onto the metal wall-plate and check the TLX
7506 is still in radio communication with the RF
Receiver. This is easily done by adjusting the set
point to switch on and off the heating system several
times and checking the green indicator on the RF
Receiver goes on and off accordingly.
