Product description
The frost switch is placed between the heating tape or thermal tape and the power outlet. It has an external temperature sensor and automatically switches on the pipe heating (frost protection) as soon as the ambient temperature is lower than +3 °C. Other applications: switching on an electric frost heater in a holiday home or chalet.
When the temperature rises to +5 °C, it automatically interrupts the power. A delay time of approx. 60 min applies to switching off. This is necessary for sufficient frost protection with both slow and fast changes in temperature. Advice: For control without delay, with ON + OFF temperatures of your choice, the Temperature Controller is recommended.
The fixed switching temperatures are optimal for protecting the water pipe against freezing. At safe temperatures, the heating tape can therefore never consume power. You can see immediately from the colored ring whether the mains voltage is present (green). As soon as it starts to freeze, the LED ring turns red and the tape receives mains voltage. This way you can always easily check whether the frost protection is switched on. And you don't have to set anything else.
Applications
Frost switch with external sensor
You can also use this frost switch outdoors. For this reason, the plug-in part (socket) is located on the underside of the housing. You can attach the external sensor (for example) to the pipe to be protected, under the insulation.
