Models and Features
• Models with 1 output- TB6980A1007 (Floating)
- TB7980A1006 (Analog 0-10V or 2-10V)
• Models with 3 outputs- TB6980B1006 (1st output is floating)
- TB7980B1005 (1st output is analog 0-10V or 2-10V)
- 2nd output can be configured for: Analog 0-10V Analog 2-10V 24V
- 3rd output is 24V only
• Features for all models- Automatic changeover (duct sensor required)
- Manual changeover (remote switch or relay required)
- Night setback
- Min and Max temperature setpoint stops
3
Applications and Accessories

Configuration and Operation
• Configuration- Dip switches
Temperature display, F or C (SW1) Access mode (SW2) Output 2 type (SW6)
• This sets output 2 type (analog or triac)
• Operation- Backlight (on for 12 seconds)
- Temperature setting by 1° increments (2°F in changeover)
- Output display (Hold Override for 4 seconds)
20
Operation (continued)
• Operation- Changeover
Manual changeover (contact) Automatic changeover (9°F differential between duct and room) Night setback
• Override (2 hours)
• Error codes- E1 (internal sensor defective)
- E2 (internal sensor shorted)
- E3 (external temperature sensor defective or not connected)
- E4 (external temperature sensor shorted)
