A Network Management Control System for a multi-space building having individual space heating and cooling units in each space that ties the individual heating and cooling units together with a central computer which allows the remote computer to interrogate and overwrite parameters set at each local heating and cooling unit.

Network management control

A defrost cycle for a heat pump system which optimizes the efficiency of the heat pump by initiating defrost depending upon the relationship of both the outdoor coil ambient temperature and the outdoor coil refrigerant temperature with a predetermined temperature reference level.

Defrost control

A space temperature control which prevents overshoot and undershoot of a desired space temperature by adjusting a subsequent sensed space temperature as a function of a previous sensed maximum space temperature to deenergize a space conditioning device at the adjusted temperature to maintain the desired space temperature.

Active anticipatory control

A adjustable defrost cycle for a heat pump system which ensures that the outdoor coil is maintained free of frost by adjusting a defrost initiation reference level for the initiation of the next subsequent defrost cycle depending upon the time period of the previous defrost cycle.

Heat reclamation from and adjustment of defrost cycle

Electronic control module enclosure

An outdoor coil temperature detection scheme in a heat pump system effective for developing outdoor ambient temperature indications from outdoor coil temperature data, for use in heat pump control.

Outdoor ambient temperature determination

A compressor speed control arrangement with provision for selecting compressor speed in view of changes in room ambient temperature, detecting a feedback signal indicative of compressor speed, calculating actual compressor speed, developing an error signal between selected and actual compressor speeds and modifying compressor speed in view of the developed error signal.

Electrically commutated, variable speed compressor control system

A method of operating a switching relay with inductive coils by a microprocessor control to prevent the transient electro-magnetic noise caused by the switching relay from resetting the microprocessor and restarting the program at the beginning. Prior to switching a relay a code is loaded in the memory of the control. After the relay switching noise causes a reset, the control detects the code and jumps back to its proper place without a disruption in its operation.
