1. A room heater comprising:
a first room-temperature detecting means; and a control means configured to control temperature by adjusting an amount of heat to be provided to room air according to a difference between a detected temperature detected by the first room-temperature detecting means and a predetermined set temperature wherein a thermostat including a second room-temperature detecting means provided separately from the first room-temperature detecting means of the room heater is coupled to the control means, the thermostat is configured: to output an on-command when a detected temperature detected by the second room-temperature detecting means becomes a predetermined first reference temperature or below; and to output an off-command when a detected temperature detected by the second room-temperature detecting means becomes a predetermined second reference temperature or above, or when the thermostat is manually operated to be switched off, the second reference temperature being set higher than the first reference temperature, the control means is configured: to operate the room heater on receiving an on-command from the thermostat; to stop the room heater on receiving an off-command from the thermostat; and to update a set temperature according to a difference between a detected temperature detected by the first room-temperature detecting means of the room heater on receiving the off-command from the thermostat, and the set temperature, the updated set temperature being used for controlling temperature when an on-command is received again, and when the off-command is received before passing a predetermined period of time after receiving the on-command, the updating of the set temperature is prohibited if the detected temperature detected by the first room-temperature detecting means of the room heater is a predetermined minimum lower reference temperature or below. |
