Abstract

Two-point controllers (2, 3) are provided for a two compartment heating installation, one having a narrow switching hysteresis (3) and the other having a wide switching hysteresis (2). The controllers receive, in parallel, a control deviation +/- Kw and are linked to two setting members (Y, Y2) via a two-pole changeover switch (4a, 4b). At start-up both controllers operate and in a subsequent control stage the controller 3 cycles. When the disconnecting points of both controllers (2, 3) have been exceeded by the control deviation the switch (4a, 4b) is changed-over and the connections to the setting members interchanged when the control deviation falls below the switching-on points of both controllers (2, 3) the switch is restored.
