⚠️ Common Symptoms / When to Replace
You may need to replace your thermostat if you notice:
-
🔸 Zone temperature drifts or fails to hold setpoint
-
🔸 HVAC damper or actuator doesn’t respond to changes
-
🔸 Thermostat display is unresponsive or erratic
-
🔸 No signal or inconsistent control to the VAV box
-
🔸 Excessive cycling or failure to maintain comfort levels
❓ (FAQ) Frequently Asked Questions
Q: What is a “floating” thermostat output?
A: A floating output sends incremental open/close control signals to modulate an actuator rather than on/off signals, allowing more precise temperature control.
Q: Can this thermostat be used for both heating and cooling?
A: Yes — it supports heating, cooling, or both, with adjustable setpoint limits.
Q: Does it include a Night Setback feature?
A: Yes — the NSB terminal allows connection to a central time clock or occupancy sensor for energy savings during off-hours.
Q: Can I replace a T6984D1046 or T6984E1043 with this?
A: Yes — the TB6980B1006 is a direct replacement for those models.
Q: Is this suitable for hydronic perimeter heat?
A: Absolutely. It’s designed for hydronic and VAV zone control applications.
🛒 Shopping Tips
-
✅ Check system voltage before installation — must be 24V.
-
✅ Confirm actuator type supports floating control signals.
-
✅ Use the NSB feature for energy-efficient scheduling.
-
✅ Mount on an interior wall away from direct sunlight or drafts for best accuracy.
-
✅ Replace existing thermostat wiring one-to-one to avoid miswiring
