Abstract

The control system consists of two discrete parts. The first is operated from two resistances of a Wheatstone Bridge and has one resistance sensitive to external temperatures. The second sensitive regulates the internal temperature of the building according to a weekly, daily and hourly programme. This control operates the circulating pump through a day and night thermostat. The system is connected to an electrical clock so that the controls and temperatures may be set the required figures. Two separate resistances control the burners to the boilers on or off as required. The system may be adapted to a number of installations in parallel.
