ABSTRACT:
An optimal start programmer for starting a heating or cooling cycle for an intermittently occupied building includes a digital counter which is enabled at the start of a pre-occupancy "search" period and accumulates counts from a timing source. A digital to analog converter is responsive to the cumulative output count of the counter circuit for generating a staircase or ramp signal which provides a time-variable set point signal during the search period. In the heating mode, the reference signal to the digital to analog converter is a signal representative of the outdoor ambient temperature; and in the cooling mode the reference is a constant signal. The operating mode of the system during the search period is determined by a mode selection circuit which is responsive to a heating mass signal and a cooling mass signal to automatically determine whether the system is to operate in a heating mode, a cooling mode or an inhibit mode in which neither the boilers nor the chillers are actuated.
