Finder 1T.01.1 opbouw ruimtethermostaat 7 tot 30 °C (1T011)

Maintaining a consistent indoor temperature without constant manual adjustment is a common challenge. The Finder 1T.01.1 room thermostat solves this by automatically switching heating or cooling equipment based on the ambient temperature you select. Its bimetallic sensor responds to room temperature changes, making it a reliable, energy-saving control for residential and light commercial spaces.

Who is it for

This thermostat is ideal for homeowners, electricians, and facility managers who need a simple, robust temperature control for electric radiators, convectors, underfloor heating, or fan coil units. It suits installations where a digital display or smart connectivity is not required, and where a surface-mounted unit is preferred for easy wiring access.

Main features

• Mechanical operation with bimetallic strip sensor – no power supply needed for the switching contact.
• Adjustable temperature range from 7 °C to 30 °C, suitable for frost protection and comfort heating.
• Single-pole changeover contact (SPDT) for flexible control of heating or cooling loads.
• High switching capacity: 16 A at 250 V AC (resistive), 6 A at 250 V AC (inductive).
• Compact surface-mounted housing in white (RAL 9010) with screw terminals for conductors up to 2.5 mm².
• Selectable heating or cooling mode via internal switch.
• Low differential (hysteresis) of less than 1 K at 20 °C for stable temperature control.

Tips

For best performance, install the thermostat on an interior wall about 1.5 m above the floor, away from direct sunlight, drafts, and heat sources. Use the internal selector to match the system type (heating or cooling) before wiring. The potential-free contact allows control of low-voltage circuits as well, provided the load stays within the specified minimum switching power.
