•For trouble-free installation, which should be carried out by a
qualified installer, follow the installation chart sequence.
•Follow all current national safety code requirements. In particular
ensure that a properly sized and connected ground wire is in place.
•After installation thoroughly test the system operation and
explain all system functions to the owner.
•Leave this manual with the owner for consultation during
future periodic maintenance.
•Dispose of packaging material in accordance with local
requirements.

Power
Note that the Room Controller requires no batteries and is not
“power stealing”. It requires 12 VDC to be connected for
proper operation, which is easily obtained from the Unit
connected to it.
The Room Controller will not operate without this connection.
If the indoor air sensor on the Room Controller has been
selected, it should NOT be mounted:
•Close to a window, on an outside wall, or next to a door
leading to the outside.
•Exposed to direct light and heat from a lamp, sun, fireplace,
or other temperature-radiating object which may cause a false
reading.
•Close to or in direct airflow of a heating or cooling supply.
•In areas with poor air circulation, such as behind a door or in
an alcove.
•Maximum of 150 m of total network wiring.

AQUASMART Room Controller
ENGLISH
•Match and connect equipment wires to proper terminals in the
connector block.
Both power and communication wires must be connected
correctly for proper Room Controller operation.
•Push any excess wire into the wall and against mounting
base.
If the air sensor is being used on the Room Controller, seal
hole in wall to prevent air leaks.
Leaks can affect sensor operation.
•Push the Room Controller snap hinge to the base.
Mounting
WARNING:
Before installing the Room Controller, turn off all power to
the Unit that will supply power to the Room Controller.
Electrical shock can cause personal injury or death.
• Turn OFF all power to unit.
•Open the Room Controller rear mounting base to expose
mounting holes.
The base can be removed to simplify mounting (snap apart
carefully at hinge to separate mounting base from remainder
of the Room Controller).
•Route the Room Controller wires through the large hole in
the mounting base.
Level mounting base against wall (for aesthetic value only the
Room Controller need not be level for proper operation) and
mark the wall through the 2 mounting holes.
•Drill two 5 mm mounting holes in wall where marked.
•Secure mounting base correctly ( ) to wall with 2 screws
and anchors provided, (additional anchoring holes available
for more secure mounting if needed) making sure all wires
extend through hole in mounting base.
•Adjust length and routing of each wire to reach the proper
terminal in the connector block on the mounting base, with 6
mm of extra wire (strip only 6 mm of insulation from each wire
to prevent adjacent wires from shorting together when
connected).
