Honeywell 031.0429.00 Thermostat FT6961-60

Frost protection thermostat Honeywell FT6961-60 Single-stage capillary thermostat for ventilation and air conditioning systems Honeywell FT6961-60 — a specialized single-stage frost protection thermostat (Frost Protection Thermostat) designed for use in ventilation, air conditioning, and cooling systems. The device is also known under part number 534.805.005 in warehouse inventory systems. This thermostat provides reliable protection of heaters and heat exchangers from damage when air temperature drops. Purpose and application: Thermostats of the FT69 series are designed for use as frost protection devices to ensure the safety of air heaters located downstream in ventilation and air conditioning systems, as well as heat exchangers in cooling systems. The device can also be used to control electric heating systems and activate acoustic or optical alarm systems. Typical applications: Protection of water heaters in supply ventilation units Protection of heat exchangers in cooling systems Control of electric heating systems Activation of emergency alarms when temperature drops Model FT6961-60 is equipped with automatic reset function. This means that after normal temperature is restored, the device automatically returns to operating state without manual intervention. Unlike model FT6960 with manual reset, FT6961 is optimal for fully automated systems. Operating principle: The thermostat is equipped with a gas-filled copper capillary sensor 6 meters long. The capillary tube is filled with a special temperature-sensitive liquid and is an integral
