An apparatus is described which gives a controlled daily cycle of temperature. The hand of a 24 hr. clock is connected by a rod to the arm operating a thermostat contact and moves the contact slowly backwards and forwards. Its method of use is described and the shape of curve it produces is expressed as a mathematical formula. A method of obtaining a nearly constant relative humidity is described.
