INFRARED
SENSOR
INDICATORS
When the battery becomes low, the green light
will turn off but will blink on every two and a
half seconds. When the battery becomes
exhausted, the unit will fail to operate.
TEST BUTTON
To use this button to manually turn an output
on or off, proceed as follows:-
The HC706 will have been set up to suit the
programming of your main controller (Compact,
Companion or Freeway).
To control the device(s) connected to the
HC706, simply select the appropriate position
from your controller menu.
The outputs of the HC706 may be set up to
operate in many different ways. The engineer
will have explained how your system works at
the time of installation.
• Hold the button in. After a short delay,
any outputs which are on will be turned off.
• After a second or so, Channel A will turn
on.
• Next, Channel A will turn off and Channel B
will turn on.
• Finally after a further delay, both channels
will turn on.
There are 3 indicator lights on the front panel.
The 2 orange Channel lights show when the
outputs are activated.
The green Status light indicates when mains
power is present and the state of the internal
battery.
When the mains power is on, the green light
should be on all the time.
When the mains power is removed and the unit
is operating from its internal battery, the green
light will blink off every two and a half seconds.
If the green Status light is on continuously, go
to step 2.
1.
Check that the mains plug has not been
removed from the wall socket and that
power is present at the socket. If the
green Status light is still not on, contact
Possum Controls Ltd.
2.
Press and hold in the TEST BUTTON,
as already described. If the orange
Channel lights do NOT operate correctly,
contact Possum Controls Ltd.
3.
Check that there is nothing between your
controller and the sensor on the HC706
unit, which could stop the infrared
signals from being picked up by the unit.
4.
If your installation includes a remote
infrared sensor, ensure that the remote
sensor is still mounted where the
engineer installed it and has not fallen
down or turned away.
5.
Check that the path between your
controller and the remote sensor is clear.
There is a button located in the recess on
the underside of the unit which may be used
to manually operate the outputs and to test
the unit.

IF YOU HAVE A PROBLEM
If the button is still held, both outputs will be
turned off after 1 second and the sequence
will then repeat at 1 second intervals while
the button is held in.
To set the unit to a particular output state,
just release the button when the orange
Channel indicator lights show the required
states.
BUZZER
The HC706 unit contains a buzzer which may
have been set up to sound when one or more
outputs are operated. This buzzer may also
be set up to warn of a mains failure.
NOTE: If a remote sensor is installed,
there will be a cable fitted in the third
hole from the right, on the underside.
If you are still unable to solve the problem,
please contact Possum Controls Ltd. at the
address overleaf for assistance.
