Schneider Electric (Viconics) VT7652H5531E Thermostat

The Schneider Electric (Viconics) VT7652H5531E is a high-performance 3H/2C heat pump thermostat engineered for rigorous commercial rooftop and heat pump applications. As a direct replacement for TEC2201-4, this unit facilitates a seamless field upgrade while introducing advanced LonWorks communication protocol for building automation integration. The VT7652H5531E features an onboard Passive Infrared (PIR) occupancy sensor, allowing for ASHRAE-compliant energy savings through setpoint setbacks during unoccupied periods. Designed with Proportional plus Integral (PI) control logic, it eliminates temperature offset and provides precise staging for multi-stage HVAC systems. The dual-line backlit LCD display and 5-button interface allow technicians easy access to over 20 configuration parameters, including adjustable deadband and fan control (On/Auto/Smart). With 7-day programming capability and non-volatile memory for permanent program retention, this thermostat ensures reliable operation in demanding environments without the need for constant recalibration or onsite adjustments.

• Universal Compatibility: Serves as the precise replacement for Johnson Controls TEC2201-4, utilizing existing wiring footprints for faster commissioning.
• Enhanced Energy Logic: Integrated PIR motion sensor automatically toggles between occupied and unoccupied modes to reduce equipment runtime.
• Network Integration: Native LonWorks communication allows for remote monitoring and setpoint adjustment via centralized Building Management Systems (BMS).
• System Protection: Includes configurable anti-short cycle protection and smart fan logic to prevent compressor damage and improve air distribution.
• Flexible Staging: Supports up to 3 heating and 2 cooling stages, making it ideal for high-capacity heat pump units with auxiliary heat.

Is the VT7652H5531E compatible with standard 24VAC systems?
Yes, this controller operates on standard 20-30 VAC, 50/60 Hz power. Terminal connections are designed for 16-18 AWG wiring for power and 22-24 AWG for LonWorks communication bus lines.

Does this model support remote temperature sensing?
Absolutely. The unit includes dedicated inputs for remote room sensors and outdoor air sensors (OSA), allowing for discharge air monitoring and optimal start recovery based on ambient conditions.

What is the benefit of the 'Smart' fan mode?
The Smart fan setting ensures the blower remains active during occupied periods to maintain ventilation requirements, then switches to cycling with the compressor during unoccupied hours to maximize efficiency.
