DRI-365
Installation Manual
3.5 Remote Sensor
DRI-365 units are supplied with 15 metres of 2 core cable pre-wired and
ready to connect to the Remote Sensor.
The Remote Sensor is used in conjunction with the units internal sensor
to allow the system to operate in “Heat Recovery Mode”.
The sensor is fitted with an LED indicator which is capable of providing
various status information if required:
•
FLASHING RED -
after 5 years from commissioning to indicate
that the filters need cleaning or replacement.
•
PERMANENT RED -
to indicate a failure.
•
GREEN -
to indicate when the system is in ‘Heat Recovery Mode’.
•
AMBER -
which indicates normal operation.
If it is desired to disable the LED function completely the LED itself may
be ‘bent’ over to one side in order to render it ‘blind’ to the user.

3.5.1 Remote Sensor Installation
For good EMC engineering practice, power supply output cables
and any sensor cables should not be placed within 50mm of other
cables or each other.
The Remote Temperature Sensor incorporates a clip-in fixing bracket
which can be removed for easy fitting to a suitable surface.
•
Select a suitable location for the sensor e.g. close to ceiling height
in a bedroom or hallway BUT NOT WITHIN 3 METRES of the
diffuser.
•
Arrange the connecting cable in position. Leave approx. 75mm of
the cable free at the mounting point to ease the connection of the
cable.
•
Carefully separate the sensor from the fixing bracket using a small
screwdriver.
•
Fix the bracket to the wall and arrange the end of the cable to fall
through the slot cut in the bracket.
•
Carefully separate the two sensor halves to reveal the wiring
connection terminals.
•
Feed the twin cable through the cut out rear half and connect the
two wires to the terminals.
•
Reassemble the sensor body halves.
•
Clip the sensor body in the fixing bracket arms and adjust the
sensor body to the desired position.
The remote sensor is connected to the circuit board via the supplied
2 core cable and into the connector labelled ‘Remote Sensor’ on the
circuit board.
