Main setting items
(1) Setting Temperature Range (DN 18 to 1F)
• Set the temperature range for heating (zone 1,
zone 2), cooling, and hot water.
• The upper-limit and lower-limit temperatures of
each mode can be set.
(2) Setting Heat Pump Operation Conditions for Hot
Water Supply (DN 20 and 21)
• Set the heat pump start water temperature and
heat pump stop water temperature.
• The heat pump starts working when the water
temperature lowers below the set start water
temperature. It is recommended that the default
value be used.
(3) Compensating Hot Water Temperature (DN 24
and 25)
• Compensate the target temperature from the
remote controller set temperature when the hot
water temperature lowers below the set outside
air temperature.
(4) Setting Hot Water Boost (DN 08 and 09)
• Set the control time and target temperature
when the HOT WATER BOOST is operated.
(5) Setting Anti-Bacteria
• Set the control for the hot water cylinder when
ANTI BACTERIA is operated.
• Set the target temperature, control period, start
time (24-hour notation), and target temperature
retention period.
• Make this control setting according to
regulations and rules of respective countries.
(6) Setting Priority Mode Temperature
• Set the outside air temperature that changes the
preferred operation mode.
• Hot Water - Heating Switching Temperature
Heating operation takes precedence when the
temperature lowers the set temperature.
• Boiler HP Switching Temperature
When the temperature lowers the set
temperature the external boiler output is made.
(7) Setting Heating Auto Mode Temperature (DN 27
to 31, A1 to A5)
• Compensate the target temperature when Auto
is set for temperature setting on the remote
controller.
• The outside air temperature (T0, T1 and T3) can
be set individually.
• The target temperature can be set to a value
from 20 to 55 °C.
• However, A > B > C > D > E.
• The entire curve can be adjusted plus and minus
5 °C by DN27.
Default setting
You can choose either a percentage or a fixed
value as the setting method of zone 2

(8) Setting Frost Protection Temperature (DN 3A to
3B)
• Set the function when the Frost protection is set
to“ONˮ.
• Set enabling/disabling of this function and the
target water temperature.
• If disabling is set, the frost protection operation
is not performed even when the Frost protection
issetto“ONˮ.
(9) Setting Frequency of Output to Internal Heater
(DN 33 to 34)
• The increase/decrease time is used to set the
response time.
