Alpha E-Tec S 20 and 30 - Technical Data
Note: This Appliance Must Be Earthed
Optional integral single channel controls are available if required.
Note: Only use the Alpha two channel controls. Do not fit any single channel controls*.
Fig. 2.3 shows the Internal two channel clock option for S or Y plan. Alternatively bring a Switched Live from external controls
to terminal 1.
DO Not connect an Alpha Climatic control when the proprogrammer clock is connected.
