• 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.
• It is not possible to interconnect the FCU to the EHS they are working independently. Supply temperatures above 65°C
are not allowed when using Samsung FCUs.
NOTE
A buffer may be required in the secondary circuit, if the active volume is too small to operate a minimum of
600 seconds during part load operation.
Especially when the devices have individual (thermostatic) valves, to control the flow over the devices.
