(*1) Height difference : The difference of the height between the corresponding indoor uint and the indoor unit installed at the lowest place.
For example, When the indoor unit is installed 40m higher than the indoor unit installed at the lowest place, select the option “1”.
(*2) Distance : The difference between the pipe length of the indoor unit istalled at farthest place from an outdoor unit and the pipe length of the corresponding indoor unit from an outdoor unit.
For example, when the farthest pipe length is 100 m(328 ft) and the corresponding indoor unit is 40 m away from an outdoor unit, select the option “2”. (100 - 40 = 60m)
(*3) For MTFC option, MTFC(Multi Tenant Function Controller) kit is required.
(*4) Heater operation when the SEG9 of 02 series installation option is set to using hot water heater or when SEG15 is set to using external heater
e.g. 1) Setting 02 series SEG9 =”1” / Setting 05 series SEG18 = “0”: Hot water heater is turned on at the same time as the heating thermostat is on, and turned off when the heating thermostat is off.
e.g. 2) Setting 02 series SEG15 =”2” / Setting 05 series SEG18 =”A”:Room temp. ≤ set temp. + f(heating compensation temp.)
- External heater is turned on when the temperature is maintained as 4.5 °C for 10 minutes. Room temp. > set temp. + f(heating compensation temp.)
- External heater is turned off when the temperature is maintained as 4.5 °C + 1 °C (1 °C is the Hysteresis for On/Off selection.)
When the SEG 3 is set as “1” and follow Auto Change Over for HR only operation, it will operation, it will operate as follows.
