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)

We ordered a Honeywell TB7980A-1006 Thermostat with Night Setback (NSB). We were expecting a time schedule to set when NSB occurs (eg, after hours, weekends). The TB7980 does not have a time schedule (?). The NSB is activated via dry contacts. Please provide a Honeywell product # to permit dry contact output with a time schedule to work with the TB7980-1006 T-Stat. Thank you.

Can't find the answer to your question in the manual? You may find the answer to your question in the FAQs about the Honeywell TB7980 below.

Where is the best location to place the thermostat?

The best place for the thermostat is the room where you spend the most time, in many cases the living room or kitchen. Place the thermostat about one and a half metres above the floor, not in the sun and not on an outside wall.

What is the dead band of a thermostat?

If your thermostat has a dead band, your installation is, as it were, 'at rest'. The thermostat only switches on when, for example, the difference deviates more than 2˚C from the set room temperature.

What is the ideal room temperature?

Most people find that the ideal room temperature is between 19 and 22 degrees Celsius.

How do I adjust the temperature setting on my Honeywell TB7980 thermostat?

Press the "Up" or "Down" arrows located on the thermostat's display to adjust the temperature setting to your desired level.

What should I do if the thermostat's display is not turning on?

Check if the thermostat is receiving power by ensuring it is properly connected to a functioning power source. If not, resolve the power issue first.

How can I switch my thermostat between heating and cooling modes?

Press the "Mode" button on the thermostat's display to cycle through the available modes until you reach the desired heating or cooling setting.

What action should I take if the thermostat is not maintaining the set temperature?

Verify if the thermostat is installed in an optimal location away from heat sources or drafts. Adjust the thermostat's temperature differential setting if needed.

How can I program my thermostat to follow a scheduled temperature program?

Use the thermostat's scheduling function to set different temperature levels based on specific times of the day. Press the "Program" button and follow the on-screen prompts to set your desired schedule.
