Description
The TB6980/TB7980 digital thermostats provide proportional plus integral individual space temperature control in zoned commercial HVAC systems such as hydronic and pressure dependent VAV with or without reheat. There are four different models:
- TB7980A(singleoutput,modulating)
- TB6980A(singleoutput,floating)
- TB7980B (multiple output modulating)
- TB6980B (multiple output, floating)
Depending on the models, the thermostat can have up to three out- puts for the following applications:
Floating or Modulating damper/valve actuator control
Damper/valve actuator control with duct reheat and auxiliary heat (B models only)
Hydronic systems (room control, perimeter heating and cooling)
