LK 556 AntiFreeze protects your heating system, usually in an air/water heat pump, if the fluid temperature should drop below +3°C by draining the system. This prevents the heating system from freezing.
If the valve opens and drains the system, no action is required to reset the valve, the system can be refilled again as soon as normal circulation in the heating system is resumed.
Insulation is available as an accessory for maximum energy saving.
Protects the heating system from frost damage. Drains the heating system when the temperature drops below +3°C.
