<p>PURPOSE:To allow a simple circuit to regulate temperature a specific time later to different temperature from current temperature by providing two temperature regulators having the 1st set temperature and the 2nd set temperature in parallel and switching them through a timer. CONSTITUTION:A fan motor 11 for temperature control is driven by a commercial power source 12 through the contact 16a or 16b of the timer 16c and the parallel-connected temperature regulator 15 or 14. The temperature regulators 14 and 15 control switches 14a and 15a by temperature sensors 14c and 15c provided to an air passage. Desired current temperature is set by the temperature regulator 14, desired temperature a desired time later is set by the regulator 15, and desired time is set by the timer 16c. At the desired time, the contact 16b is opened and the 16a is closed. Consequently, the simple circuit performs regulation to different temperature the desired time later. This is suitably used to set room temperature (heating or cooling) during sleeping.</p> |
