Language Operator Interface
The TC Modular includes a simple, yet powerful,
menu-driven English Language Operator Interface
that provides, among other things:
● Point monitoring and display
● Point commanding
● Historical trend collection and display for multiple
points
● Event scheduling
● Program editing and modification via Powers
Process Control Language (PPCL)
● Alarm reporting and acknowledgment
● Continual display of dynamic information
Built-in Direct Digital Control
Routines
The TC Modular provides stand-alone Direct Digital
Control (DDC) to deliver precise HVAC control and
comprehensive information about system operation. It
receives information from sensors in the building,
processes the information, and directly controls the
equipment.
The following functions are available in the TC
Modular:
● Closed Loop Proportional, Integral and Derivative
(PID) control.
● Logical sequencing.
● Alarm detection and reporting.
● Reset schedules.
Built-in Energy Management
Applications
The following applications are programmed in the TC
Modular Series and require simple parameter input
for implementation:
● Automatic Daylight Saving Time switchover
● Duty cycling
● Economizer control
● Event scheduling
● Holiday scheduling
● Night setback control
● Peak Demand Limiting (PDL)
● Temperature-compensated duty cycling
● Temporary schedule override
