There is provided a regulator for wall thermostats. The regulator is operated by a timer, and provides a warm air stream upwardly beneath a thermostat to cause the thermostat to lower the house temperature between specific hours, such as at night, and cuts off the warm air stream for the remainder of the day. A housing defines an air passage which has manual means for restricting it to a greater or lesser degree. Illumination and heating means are provided within the housing which simultaneously heats the air to promote convective flow upwardly, and illuminates the manual means.
