Title: Central heating control system - with pump speed variation dependent on difference between actual and desired temp. values
IPC: G05D23/20
Filed: 1976-06-10
Abstract: The central heating control system is for use where the water or other liquid is pumped through a circuit between the boiler and one or more radiators.
