Field Setting Mode
External Backup Boiler for Space Heating (Field Option) (FSV#4031~4033)
• The FSV #4031 should be set to "1 (Yes)" to use a backup boiler as an additional heat source.
(default: "0 (No installation)")
• Priority of backup boiler and heat pump is defined by FSV #4032 (default: "0 (OFF)")
• To compensate the lowered heat pump heating performance under very cold weather conditions, the
Mixing valve Installation (Field Option) (FSV#4041~4046)
• The FSV #4041 should be set to "1 or 2" to use mixing valve.
4041 =1 : Controlled based on the temperature difference (4042, 4043)
4041 =2 : Controlled based on the temperature difference of the WL value
• Even when setting #4041 to "1", the mixing valve is basically operated by the WL valve of the FCU/Floor,
but if zone control is not used (FSV #4061 = "0") and the Fcu and floor are simultaneously thermo-on, it is
controlled based on the temperature difference (4042, 4043).

• FSV #4042 / #4043 is for adjusting temperature difference between Tw3 (Tw2) and Tw4.
• FSV #4044 determines the mount of the opening/closing degree of the valve per operation, and the larger
the set number, the greater the opening/closing degree per operation. It operates every FSV#4045 set
interval.
• When using mixing valve, FSV #4046 should be matched with mixing valve running time charateristic. (set
according to the mixing valve specifications.)
NOTE
• AE200DNX*** / AE160DNZ*** (2 Zone-built in) are configured to allow the Mixing Valve to operate.
