All models achieve new MEPS standard.
  • Page 5 10°C HEAT Operation The room temperature can be set to go no lower than 10°C, thus ensuring that the room does not get too cold when not occupied. Caution) • When the room temperature is higher than 10°C, “10°C HEAT” operation does not start. Operation starts and maintains the room temperature at 10°C when the temperature drops below 10°C.
  • Page 6: Wireless Remote Controller

    WIRELESS REMOTE CONTROLLER FEATURES Four kinds of timer setup (ON/OFF/PROGRAM/SLEEP) are possible. Four kinds of timers. Easy operation. Easy to change transmission code (4 patterns) by button operation. Built-in timers Select from four different timer programs (ON/OFF/PROGRAM/SLEEP). Program timer The program timer operates the on and off timer once within a 24 hour period. Sleep timer The sleep timer function automatically corrects the temperature thermostat setting according to the timer setting to prevent excessive cooling and heating while sleeping.
