*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 Voltage free contact for 12VDC detection by FTC (TBI.3 1, 3 and 5 pin have a positive voltage.)
● Pulse duration Minimum ON time: 40ms
Minimum OFF time: 100ms
● Possible unit of pulse 0.1 pulse/kWh 1 pulse/kWh 10 pulse/kWh
100 pulse/kWh 1000 pulse/kWh
Those values can be set by the main remote controller. (Refer to the menu tree in "7.2 Main remote controller".)
*5. As for the smart grid ready, refer to "4.9 Smart grid ready".
*6. Connectable ow sensor
● Power supply 5V DC
● Measuring range 5 to 100 L/min
Those values can be set by the main remote controller. (Refer to <Auxiliary setting> on Page 44.)
● Flow signal 0.5V (at minimum ow rate) to 3.5V (at maximum ow rate)
