*3. To turn on the boiler operation, use the main remote controller to select "Boiler" in "External input setting" screen in the service menu.
*4. Connectable electric energy meter and heat meter
● Pulse type
● Pulse duration
● Possible unit of pulse
Those values can be set by the main remote controller. (Refer to the menu tree in " Main remote controller".)
*5. As for the smart grid ready, refer to "5.5 Smart grid ready".
