Additional information on software installation and
operation is given in the documentation and help
files provided with the administration software.
All similar controllers on the system should have
the same firmware version number
A firmware download to the new controller may be
required, see the help file for further details.

Training and Technical Support
Training courses covering the installation and use
of all PAC products are regularly held at PAC
Stockport.
For further information on course availability, or to
discuss your specific requirements, contact the
Training Manager at the PAC address.
It is strongly recommended that any persons
installing or commissioning PAC products
attend a suitable training course beforehand.
Technical Support for all PAC products is provided
primarily for the use of trained engineers.
Technical support is available during normal office
hours:
08:30 to 17:30 (UK time) Monday to
Friday, excluding public holidays.
End users of PAC products should first of all
contact their installation or maintenance company
before contacting PAC.
One-Touch™ Testing
To speed up installation and testing, One-Touch™
testing is provided which allows the inputs and
outputs functionality to be tested at the controller.
There are two test modes:
View mode is for use on a configured system.
l
Active mode is for use during system configuration to
l
enable a system to be walk tested by a single person.
This is achieved by use of latching LED status which
indicate the first change in input condition.
