• The combination of a single underfloor heating zone and DHW heating requires settings of FSVs (#2091 (ext.
thermostat) or 2093 (Samsung wired remote) set to 1~4 and #3011 set to 1~2 ).
• To enable the backup heater as an additional heat source, please set FSV (#4021, 4022). The backup heater must be
installed and operational by control logic. When ambient conditions can reach below 24°C.
• For the heating compensation at cold weather conditions and backup during defrost, please set FSV (#4023, 4024,
4025) accordingly.
