(c) In case of installing on the control board
Please be sure to lock the control board to protect persons
from the electric shock.
Avoid usage of heat-retaining materials and heat-insulating
materials because these can result in heat buildup and
adversely affect the operation of the central control.
(d) In case of embedding in a wall
Please check that there is sufficient space inside the wall.
If the temperature inside the wall exceeds 40˚C, install the
central control on the control board.
Caution
Please do not install devices that can cause the ambient
temperature to rise in the same control board. Also, do
not install multiple controllers in the same control board.
These can cause heat to build up and result in false
operation. If multiple central control must be installed in
the same control board, take corrective measures to ensure
that the temperature in the control board does not rise
above 40˚C such as by installing cooling fans.
When performing the continued installation of multiple controllers, be sure to obtain the distance between units and service
space as shown in the figure.
