Tempro builds control solutions for high-demand HVAC environments. Our line voltage thermostats used in air conditioning systems regulate 120V or 240V power directly to AC equipment. These thermostats suit standalone systems that do not use low-voltage controls. They deliver precision, fast installation, and long-term reliability.

Tempro thermostats control cooling systems with speed and accuracy. They work in commercial buildings, industrial facilities, and zone-based applications. Use them in window units, PTACs, or ductless split systems.

Direct Power Control for Better Performance

Our thermostats switch the power circuit directly. This eliminates the need for relays, control boards, or transformers. AC systems respond faster and run more efficiently.

We offer models with snap disc or digital sensors. These respond quickly to temperature changes. Each unit includes an adjustable setpoint from 40°F to 90°F. Rugged housings resist vibration, dust, and moisture—ideal for HVAC settings.

Fast Installation, Simple Wiring

Tempro thermostats reduce wiring complexity. Technicians can install them quickly with fewer tools. We offer both single-pole and double-pole models for wide compatibility.

Each design supports quick diagnostics and easy field service. You won’t need added hardware, which keeps costs low and performance high.

Trusted in Critical Cooling Applications

Tempro line voltage thermostats operate in:

  • Data rooms and telecom closets – Maintain thermal safety for sensitive equipment.

  • Refrigerated zones – Control temperature for food and pharmaceutical storage.

  • Retail and hospitality – Enable precise zone control without central automation.

These systems need reliable switching and tight control. Our thermostats deliver both.
