It looks like you are connecting the temp controller switch + time clock switch + float switch all in series? So all switches have to be closed for the heater to come on?
That itself is fine, but the problem is that yellow light is also in series! That is bad.
Keep the three switches in series, but connect the yellow light in parallel to the SSR "coil" inputs.
So the three switches must all be closed for the SSR to be activated, and when the SSR is activated with power at its coil the yellow light also gets power.
