FEMA FT69 | Single-Stage Frost Protection Thermostats | 1.8, 3 or 6 m capillary
FEMA FT69 single-stage protection thermostats sense temperature along the whole capillary in air heating and climate control systems. If any 30 cm section of the capillary falls below the set point, or if the capillary is damaged, the thermostat switches off. The 3 m and 6 m versions come with six mounting retainers and the 1.8 m version with three.
Key features
- Responds to any 30 cm capillary section below the set point
- Fails safe if the capillary is damaged
- Capillary must be looped evenly across the duct cross-section
- Fluid reservoir in the head is also temperature-sensitive
