Main setting items (refer to Function code setting table – shown below descriptions)
(1) Setting Hot Water Temperature Range (function codes: 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 (function codes: 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 (function codes: 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 (function codes: 08 and 09)
• Set the control time and target temperature when the HOT WATER BOOST
button on the remote controller
is pressed.
(5) Setting Anti-Bacteria (function codes: 0A and 0B / Remote controller 0D and 0C)
• Set the control for the hot water cylinder when ANTI BACTERIA
is set with the remote controller.
• 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 System Priority Mode (function codes: 22, 23 and 0F)
• 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 HP operation stops and the external boiler output is made.
Cooling – Hot Water Priority Selection
Set the priority mode between cooling and hot water when the system is running in cooling mode
(7) Setting Heating Auto Mode Temperature (function codes: 27 to 31)
• Compensate the target temperature when Auto is set for temperature setting on the remote controller.
• The outside air temperature can be set to one of three points (T1 and T3 customisable) within a range of -15 to 15°C.
• 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 function code 27.
(8) Setting Frost Protection Temperature (function codes: 3A and 3B / Remote controller 12 and 13)
• Set the function when the FROST PROTECTION
button on the remote controller is pressed.
• Set enabling/disabling of this function and the target water temperature. (FC3A and FC3B)
Set schedule end day and end time (remote controller: Fc12 and 13)
• If disabling is set, the frost protection operation is not performed even when the FROST PROTECTION
button
is pressed.
(9) Setting Frequency of Output to Internal Backup Heater (function codes: 33 and 34)
• The increase/decrease time is used to set the response time.
(10) Setting Night Setback (function codes: 26 / Remote controller 0F to 11)
• Set the function when the NIGHT
button on the remote controller is pressed.
• Set enabling/disabling of this function, reduction temperature, start time, and end time.
• If disabling is set, the night setback operation is not performed even when the NIGHT
button is pressed.
