OTS-F1 Can be used as an ambient sensing thermostat (with capillary coiled) or line sensing thermostat. Line sensing is when the bulb is attached directly to a pipe. The OTS-F1 has a fixed set point of 40ºF. The enclosure is NEMA 4X (weatherproof and corrosion resistant). The OTS-F1 comes with a rubber coated bulb which may be used in air, gases, or liquids. The maximum temperature for the sensing bulb is 140ºF. The thermostat also features a ten foot capillary.
