*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
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 website manual.

Ensure to wire thermistor wirings away from the power line and/or OUT1 to 16 wirings.
*1. The maximum length of the thermistor wiring is 30 m. When the wires are wired to adjacent terminals, use ring terminals and insulate the wires.
The length of the optional thermistors are 5 m. If you need to splice and extend the wirings, following points must be carried out.
1) Connect the wirings by soldering.
2) Insulate each connecting point against dust and water.
