THERMOSTAT AIRSEC F-3000

Airsec F-3000 – Capillary thermostat for ventilation systems. The Airsec F-3000 is a capillary thermostat designed to serve as a temperature controller for duct heaters and other heating components in ventilation systems. It enables temperature control between -30…+30 °C and operates with a single-pole changeover contact that opens or closes according to temperature.

Features:

• Application: Temperature control and frost protection for duct heaters and heat exchangers in ventilation systems.
• Control range: -30…+30 °C, adjustable via a rotary dial.
• Control mechanism: Volumetric thermal expansion with a capillary tube transferring temperature changes to a pressure bell that actuates the relay.
• Relay switching capacity: 16 A / 230 V (resistive load).
• Capillary tube length: 1.5 m, facilitating flexible installation in various locations.
• Installation: Mount on wall or directly onto ventilation duct using mounting screws.
• Enclosure rating: IP54, protected against dust and water splashes.
• Operating pressure range: 50–500 Pa.

Operating logic:

• When the temperature exceeds the setpoint, contacts P1 and 2 close.
• When the temperature falls below the setpoint, contacts P1 and 1 close.

The Airsec F-3000 is particularly suitable as an optional accessory for Airsec NK duct heaters, providing reliable temperature control without requiring a separate electrical control unit.
