VEMER - VE268900 - Klima 3V mechanical wall thermostat with fan coil 3-speed selector

Klima 3V mechanical thermostat for fan coils

The VEMER Klima 3V is a wall-mounted mechanical thermostat with gas membrane, designed specifically for controlling fan coil units in heating or cooling systems. It features a convenient front knob for temperature adjustment, a 3-speed fan selector and an on/off switch.

How a gas expansion thermostat works

A gas contained within a sealed membrane expands as the room temperature rises. The increasing pressure moves the membrane, which is mechanically linked to an electrical contact that switches the heating or cooling system on or off.

Key features

• Mechanical operation with gas membrane sensor
• Temperature setting range: 5 ÷ 30 °C
• Differential/hysteresis: Δ 1.3 °C (± 0.2 °C)
• 3-speed fan coil selector with off switch
• Setting range limitation function (ideal for public places)
• Relay capacity: 10 (1.5) A at 250 Vac
• Protection degree: IP20
• ErP Class I

Setting range limitation

The user can limit the temperature setting range with a few simple steps, preventing unauthorised people from changing the temperature settings — a useful function in public installations.

Note: when installed at altitudes above 1000 m above sea level, calibration values are not guaranteed.
