Heat Pump Variables for Space Heating (FSV#4011~4013)
• FSV #4011 for DHW priority is set to "0(DHW)" as a default. Space heating gets a priority by setting
FSV #4011 "1", but this is only valid when the outdoor temperature is lower than the specified temperature
defined by FSV #4012.
• When priority is on DHW, DHW mode (FSV #3025,default 30 mins) and space heating (FSV#3026,default
180 mins) alternately operate, and when priority is on space heating, they operate as space heating mode.
•
temperature above this value, the space heating will be turned off.
Backup Heater Variables for Space Heating (FSV#4021~4025)
• The FSV #4021 should be set to 1(Yes) to use the electric backup heater in hydro unit as an additional heat
source.
• To configure the backup heater's operating conditions by setting FSV #4023 and FSV #4024.
– When FSV #4023 is set to 0, the backup heater operates regardless of the outdoor temperature.
– When FSV #4023 is set to 1(Default), the backup heater operates when the outdoor temperature is
below FSV #4024(Default "0") to save energy; its operation is restricted at FSV #4024 or higher.
• FSV #4022 can be set to priorities such as 0 (both), 1 (backup heater), and 2 (booster heater).
• The FSV #4022 for backup heater priority should be set to "0 (both)" (Default) or "1" (backup) to use backup
heater. If FSV #4022 is not set to 2 (booster heater priority), the backup heater can be operated in case of no
booster heater demand.
• The threshold temperature for backup heater operation during defrost mode to prevent cold draft because
of chilled water can be controlled by adjusting FSV #4025. Under FSV #4025 of water outlet temperature,
backup heater Will be turned on.
NOTE
• To use both backup heater and booster heater together at the same time as set FSV#4022="0", please
check the capacity of the power circuit breaker of your house before use.
External Heater for Space Heating (Field Option) (FSV#4026)
• The FSV #4026 should be set to "1 (Yes)" to use the external backup heater as an additional heat source.
(default: "0 (No installation)")
• The operation algorithm of the External Heater is the same as the built-in Backup heater. However, it does
not work during DHW mode and disinfection mode.
• Some models cannot have that feature set. (Refer to the FSV table)
