Field setting mode
DHW Application
The FSV #3011 in the wired remote controller should be set to "1 or 2" to use DHW function.
If FSV #3011 is set to 1, the DHW operation starts based on the thermo on temperature.
If FSV #3011 is set to 2, the DHW operation starts based on the thermo off temperature.
(For example, when the current temperature becomes 45℃ under the conditions that the thermo on
temperature is 43℃ and the thermo off temperature is 48℃, the DHW turns off if FSV #3011 is set
to 1 and DHW turns on if FSV #3011 is set to 2.)
Heat Pump Variables for Controlling DHW Tank
• Maximum DHW tank temperature with R-410A(refrigerant) heat pump operation : FSV #3021,
Default 50˚C, Range : 45 ~ 50˚C.
• Temperature difference determining the heat pump OFF temperature : FSV #3022, Default 2˚C,
Range : 0 ~ 10˚C.
• Temperature difference determining the heat pump ON temperature : FSV #3023, Default 5˚C,
Range : 5 ~ 20˚C.
• DHW heating mode timer : Mode timer manage the operation terms when there are simultaneous
– FSV #3024 (minimum Space heating operating time, Default 5 min., Range 1 ~ 20 min.),
#3025 (maximum DHW time, Default 30 min., Range 5 ~ 95 min.), #3026(maximum space
heating operation time, Default 3 hour, Range 0.5 ~ 10 hour)
– Maximum operation time is applied only when both DHW and Space heating request
operation. DHW or Space heating operates continuously until reaching at target temperature
without time limitation in the single operation.
NOTE
• The FSV #4011 for DHW priority should be set to "0(DHW)"(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.
