TB6980/TB7980 62-0238 400-150-005-B 3/23/06 1/6
1. Introduction
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:
Depending on the model, the thermostat can have up to three out-
puts that can be used 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 cool-
ing)
Accessories
 R841 family of electromechanical relays
 T7770A3002 remote room sensor
 50014156-002 remote room sensor
 32004800-001 bare thermistor
 50014157-001 duct temperature sensor
2. Installation
2.1 Mounting Instructions
n Remove the thermostat from its base by unscrewing the cap-
tive screw and tilting the bottom of the thermostat up. The
screw cannot be completely removed.
o Pass the wires through the center hole of the base and secure
the base to the wall or onto an electrical box.
p Wire the thermostat. See section 2.2 for terminal designations
and section 3 for typical wiring diagrams.
q Reinstall the thermostat onto its base and secure with the cap-
tive screw.
2.2 Terminal Designations
The designations of the terminals vary according to the particular
model of thermostat. Refer to the following table for the description
of each terminal.
• TB7980A (single output, modulating) • TB6980A (single output, floating)
• TB7980B (multiple output modulating) • TB6980B (multiple output, floating)
