If the predefined application is insufficient, free outputs can
be also be controlled for fully independent function directly via
the Saia PCD® program using the S-Bus.
The room controller can also be configured as a single RIO unit
(Remote Input Output) by completely switching off the fully
independent function. The Saia PCD® station assumes control
of al the inputs and outputs.
The resulting dependency of the availability of the S-Bus com-
munication and the increase in the S-Bus cycle time should be
taken into account during the planning stage.
`
Do not install the control device/compact room controller near
windows or doors due to potential draughts. The recommended
position is on an opposite wall at a height of approx. 1.5 m.
`
Do not located the control device/compact room controller
in the path of draughts from climate control or ventilation sys-
tems.
`
Do not install it near to heat sources such as heating systems,
fridges, lights, etc. Avoid direct sun light or direct light from strong
lamps.
