TAC System 8000 Six Stage Programmable Controllers
Model Chart
The six stage electronic programmable controllers
provide proportional control of outside and return
(mixed air) dampers in sequence with staged
heating and cooling equipment. Programming of
the heating and cooling stages and relay
assignment of heating and/or cooling plus
operating level are accomplished by dual-in-line
package (DIP) switches. Proportional heating and
cooling outputs are available for valves or electric
heat coils. The six stages can be programmed for
heating, cooling, humidification, night setback, and
fan operation.
Features:
• Six stages of control, any heat-cool combination
programmable.
• One setpoint for heat/cool with adjustable deadband
between heating and cooling.
• Two input TAC System 8000 controllers.
• Automatic integrated mixed air control cycle.
• Slave operation to add additional control stages.
• Setpoints can be remotely controlled.
• Enthalpy input signal capability.
