Direct digital control is a proven control
technology that has traditionally been used
in large-scale building automation systems.
DDC has brought unprecedented control
and efficiency to building ventilation. The
PIC combines the accuracy of direct digital
control with the flexibility of an individual
room system, providing maximum control
and efficiency.
The Price Intelligent Controller (PIC) is a
cutting edge control package that offers
a new level of zone control. An advanced
and configurable proportional integral
(PI) controller allows for exceptional user
comfort and energy efficiency. Installation
of the controller and thermostat is simple
and error proof with RJ-45 (network type)
connections to the thermostat and BACnet
network.
The PIC is designed with a modular
architecture. Options such as BACnet
networking and air flow sensing are offered
as 'add-on modules'. This allows flexibility
to the customer by providing both value
in the 'core' controller as well as powerful
control and communication options with
the use of the expansion modules.
Any PIC ordered with either the BACnet or
Pressure Independent Control options will
ship with the appropriate modules installed
and mounted. Modules may also be fieldmounted
and connected to the PIC with a
single ribbon-type cable.
The PIC is available with several thermostat
options allowing the designer to match the
specific needs of the customer. Every model
of thermostat has an RJ-12 service port
allowing setup and configuration access
without having to access the plenum.

The PRICE LINKER setup tool (combined with FREE software) can be used to reconfigure
the PIC from this service port. A stand-alone setup tool 'LCD-SETUP' is available.
Alternative methods of reconfiguration include the LCD thermostats, BACnet software.
(see page G-21 for more information on setup tools)
DDC vs. Analog Electronic Contols
The PIC is a Direct Digital Controller (DDC). The PIC offers many advantages over the older
analog electronic style controllers.
1. Full tunable Proportional + Integral control for fast, accurate control with little
overshoot.
2. Digital thermostats with setup and balancing functions.
3. Multiple customizable outputs (Binary and Analog).
4. Native BACnet module for interface to building automation and polling systems.
5. Sequence of operation changeable in the field if required. |
