10. Bivalent connection
Set if heat pump linked with boiler operation.
Connect the start signal of the boiler in boiler contact terminal (main PCB).
Set Bivalent connection to YES.
After that, please begin setting according to remote controller instruction.
Boiler icon will be displayed on remote controller top screen.
There are 3 different modes in the boiler operation. Movement of each modes are shown below.
1 Alternative (switch to boiler operation when drops below setting temperature)
2 Parallel (allow boiler operation when drops below setting temperature)
3 Advanced Parallel (able to slightly delay boiler operation time of parallel operation)
When the boiler operation is "ON", "boiler contact" is "ON", "_"(underscore) will be displayed below the boiler icon.
Please set target temperature of boiler to be the same as heat pump temperature.
When boiler temperature is higher than heat pump temperature, zone temperature cannot be achieved if mixing valve is not installed.
This product only allows one signal to control the boiler operation. Operation setting of boiler shall be responsible by installer.

In Advanced Parallel mode, setting for both heating and tank can
be made simultaneously. During operation of "Heating/Tank" mode,
when each time the mode is switched, the boiler output will be
reset to OFF. Please have good understanding on the boiler control
characteristic in order to select the optimal setting for the system.
11. External SW
Initial setting: No
Able to turn ON/OFF the operation by external switch.
12. Solar connection
Set when solar water heater is installed.
Setting include items below.
1 Set either buffer tank or DHW tank for connection with solar water heater.
2 Set temperature difference between solar panel thermistor and buffer tank or
DHW tank thermistor to operate the solar pump.
3 Set temperature difference between solar panel thermistor and buffer tank or
DHW tank thermistor to stop the solar pump.
4 Anti-freezing operation start temperature (please change setting based on usage of glycol.)
