TB7980B ZonePRO Modulating Thermostat, 0-10V, 3 Outputs, 24 VAC
Controls a 0-10V or 2-10V modulating damper or valve actuator for zoned hydronic or pressure-dependent VAV systems.
Adds two heating outputs for duct reheat and auxiliary heat: a triac or analog Output 2 and a triac or contact Output 3.
Takes a remote room, return, or supply sensor, a changeover contact, and a night setback contact.
Runs on 24 VAC.
Key Features
- 0-10V or 2-10V analog output
- 2 additional heating outputs
- Setpoint 50-95 deg F
- PIA control
- Night setback input
