*1. Set the ON/OFF cycle time of the room thermostat for 10 minutes or more; otherwise the compressor may be damaged.
*2. If using outdoor thermostat for controlling operation of heaters, the lifetime of the heaters and related parts may be reduced.
*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 0.1
Those values can be set by the main remote controller. (Refer to the menu tree in "Main remote controller".)
*5. As for the SG ready, refer to "5.1.6 Smart grid ready".
