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
nRemove 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.
oPass the wires through the center hole of the base and secure
the base to the wall or onto an electrical box.
pWire the thermostat. See section 2.2 for terminal designations
and section 3 for typical wiring diagrams.
qReinstall 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)

a. If Output 2 type is set to 0-4, set the SW6 switch to Triac. If the output type is set to 5-8, set the switch to Analog (see section 4.7).
nRemove the thermostat from its base and
set the SW2 switch to MENU.
oReinstall the thermostat. The thermostat is
now in configuration mode. The first digit
flashes to indicate that the first item of the
menu can now be modified.
pTo modify the setting, use the up/down
arrows. Refer to the adjacent tables.
qPress Override to save the new setting and
go to the next item.
rRepeat steps 3 and 4 for remaining items.
sWhen the configuration is done, set the
SW2 switch back to NORMAL.
NOTE: Factory settings are inside the shaded cells.
ABBREVIATIONS
NSB - Night setback (number of degrees
the thermostat will be set back upon
receiving a setback signal)
SSR - Solid state relay (used with fast
cycling electric heaters, SSR's are a quiet
alternative to electromechanical relays.
They're typically included with electric
duct reheat equipment)
SCR - Silicon controlled rectifier (similar
to an SSR, SCR's are also quiet and
capable of switching very high current. If
used, they're usually included with the
equipment)
N.C. - Normally closed
N.O. - Normally open
