11. 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.
After Bivalent connection Set YES, there is two option of control pattern to be select, (SG Ready / Auto)
1) SG ready (Only available to set when Optional PCB set to YES)

- SG Ready input from Optional PCB terminal control ON/OFF of boiler and heat pump as below condition

*  T his bivalent SG ready input is sharing same terminal as [16. SG ready] connection. Only one of these two setting can be set at the same time.
 When one is set, another setting will reset to not set.
2) Auto (If Optional PCB no Set, bivalent control pattern will set to this auto as default value)
There are 3 different modes in the boiler operation. Movement of each modes are shown below.
1 Alternative (switch to boiler operation when drop s 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.
3) Smart
There are Energy price (both electricity and boiler) and Schedule to be set on remote controller.
Operation setting of Energy price and Schedule shall be responsible by installer.
Based on these settings, system will calculate the fi nal price for both electricity and boiler.
When fi nal price of Electricity is lower than Boiler's, heat pump will operate.
When fi nal price of Electricity is higher than Boiler's, boiler will operate.
