NOTE
• In the range except for the continuous operation range, the protection control can be active depending on the
heat source flow rate. (It is not a failure but a way of cycle protection against hot or cold water.)
• For use in the antifreeze condition, the antifreeze concentration must be rigidly managed.

1) Anti-freeze must be used when temperature of water inlet for heating is below 10°C or ground heat is used. Maintain
approprate concentation level of anti-freeze according to temperature of water inlet.
2) Strict management of anti-freeze concentration level is required. Consult Samsung before application.
