Antifreeze temperature controller RT-811

Antifreeze temperature controller from the manufacturer F&F. The product catalog number is RT-811. Intended for controlling devices in anti-icing systems, preventing freezing, e.g. gutters, stairs, driveways, etc. Until the desired ambient temperature is reached, the relay contact is in position 11-12 (red LED is on) and the heating device is switched on . When the set temperature is reached, the contact switches to position 10-11 and the heating device is turned off (the red LED goes out). A drop in temperature by the hysteresis value will turn on the heating device again (contacts 11-12 closed) until the set temperature is reached.
