This control is NOT compatible with other controls made by different manufacturers. 

If you bought your bath and it was made by Pegasus this may be the part that you need! If it is not exactly the same send me a picture. 

WE HAVE TESTED THE CONTROL IMMEDIATELY PRIOR TO DESPATCH - IT WORKS! Turn off the electric power to the control box. Test the control on the box before installing it, make sure you match the red paint mark on the cable with the red paint mark on the control. You will need to turn the power on to test the control and turn it off immediately afterwards. Then put the control in its 30mm hole with Dow Corning 785 silicone! wipe off the excess silicone on the upper surface of the bath with Andrex, turn the electronic power back on.   Can be done by a competent DIYer...
