Schneider Electric VT7225 0-10VDC Modulating Thermostat for Electric Heat

The Schneider Electric VT7225 is a microcomputer-based proportional and integral (PI) thermostat controller designed for modulating electric heat applications. This digital display thermostat provides precise temperature control for commercial, industrial, and residential HVAC systems including baseboard heaters, unit heaters, radiant panels, and VAV box control.

Multiple Output Options:

• One analog 0-10 VDC modulating output for direct control of SCR power controllers
• One 8 VDC pulsed output for 4-32 VDC triggered solid state relays (SSRs)
• One 24 VAC proportioning pulsed output for 24 VAC triggered SSRs using time proportioning control

Key Features:

• Digital backlit display for easy visibility and setpoint adjustment
• Heating setpoint range: 40°F to 90°F with ±0.9°F control accuracy
• Cooling setpoint range: 54°F to 100°F
• 24 VAC power supply (19-30 VAC, 50/60 Hz, 2 VA)
• Binary input for remote night setback timer or occupancy control
• Optional supply air sensor input for supply temperature control
• Compatible with remote temperature sensors for averaging capabilities
• Direct replacement for legacy models C1025 and T920

The VT7225 uses advanced PI control algorithms with time proportioning on a 1-second cycle to deliver efficient, accurate temperature regulation. Its compact 6" x 4.4" x 1.9" design makes it ideal for both retrofit and new construction projects in commercial buildings and industrial facilities.
