Abstract
A room heater is controlled according to a difference between a detected temperature detected by a first room-temperature detector and a predetermined set temperature. When a detected temperature detected by a second room-temperature detector falls below a first reference temperature, the operation is started on receiving an on-command from a thermostat. When the detected temperature by the second room-temperature detector has raised above a second reference temperature which is set higher than the first reference temperature, the operation is stopped on receiving an off-command from the thermostat. The room heater is controlled to raise a set temperature by a predetermined value if it does not receive the off-command by passing of a first predetermined period of time after having received the on-command or if the detected temperature detected by the first room-temperature detector has been at the set temperature or higher without receiving the off-command for a second predetermined period of time.
