The Digital Thermostat 1TP TE530B is a scheduled, programmable thermostat offering both heating and cooling modes with a digital room temperature display. It supports ON/OFF operation and proportional control with adjustable periods from 7 to 20 minutes, making it compatible with underfloor heating systems that benefit from fine temperature micro-adjustments.

Available in a battery-powered model (2×1.5V AAA/LR03 alkaline batteries, approximately 2 years autonomy) and a mains-powered model (230V 50÷60Hz). The relay output (NO/COM/NC without potential, max 5(3) A/250V) connects heating or cooling equipment directly. Cable cross-sections from 1.5 mm² to 2.5 mm² are accepted at the terminals.

Key Features

• Scheduled programming with heating and cooling selection
• Digital ambient temperature display: 0°C to +37.7°C / +32°F to +99.9°F
• Antifreeze function: adjustable from +4°C to +12°C / +39.2°F to +53.6°F
• ON/OFF with adjustable differential: 0.2°C to 1.2°C (default 0.5°C)
• Proportional control period: adjustable from 7 to 20 minutes (default 10 minutes)
• Temperature setpoint range: +5°C to +37.7°C
• Relay output: NO/COM/NC without potential, max 5(3) A/250V

Product Benefits

• Proportional control with 7–20 minute periods enables stable underfloor heating without temperature swings
• Antifreeze function protects the heating system automatically when the space is unoccupied
• Battery model (2×1.5V AAA) provides approximately 2 years of autonomous operation without mains wiring
• Three temperature levels (COMFORT / REDUCTION / OFF) allow scheduled energy saving
• 1°K/15-minute temperature change rate prevents thermal shock to the heating system
