Choosing the installation site and installation
The Room Controller 2 Location
The CRC2 can be installed on a unit only if this unit is the
Fancoil Cabinet.
For wall-mounting, follow the instructions below:
Minimum clearances
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
Power
Note that the Room Controller 2 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 2 will not operate without this connection.
Room Controller 2: Hydronic Fancoil Solutions
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.
