Then the sytem is probably copper tubing or welded steel inside concrete. the concrete mass modifies the temperature swings, so even if 180F water is let in by the solenoid, it takes a long while for the concrete to rise to 120F (and a long time for it to cool.) The same would be true of lower water temperatures, but moreso, as lower water temperatures would take longer to change the temperature of that large mass of concrete.

This is a good situation because the solenoid control can be replaced by a modern controller if necessary. First investigate what must be done to have lower water temperatures. Today's controllers compensate for the rise in slab temperature and anticipate temperature and/or flow to start reducing input well before reaching the final slab surface temperature.
