The Room Controller Location

The Room Controller can be positioned on the unit or fitted to

the wall.

If fitted to a wall, the Room Controller must be mounted:

•In the same area where the unit is located, preferably on an

inside partitioning wall.

•Approximately 1.5 m from floor.

•On a section of wall without pipes or duct work.

General information and choosing the installation site

IMPORTANT:

Read the entire instruction manual before starting the

installation.

•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.

•The manufacturer denies any responsibility and warranty shall

be void if these installation instructions are not observed.

•Inspect equipment for damage due to improper transportation or

handling: file an immediate claim with the shipping company.

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).
