My thermostat is making a beeping sound. - American Standard T373.741 3/4" Enfield Thermostatic Shower Head and Trim

So, it sounds like your Delonghi hifi heater is giving you some trouble, man. The constant beeping and the green light on the control board, it's like it's trying to tell you something. My guess is that there's something funky going on with the thermostat. The beeping is probably the heater's way of saying it can't maintain the desired temperature because the thermostat isn't working properly. And the green light, it's like the heater is still getting power and trying to do its thing, but the thermostat is holding it back.
One thing you could try is checking the thermostat settings and making sure they're all good to go. If the settings are chill, but the problem persists, it might be time for a new thermostat. You could also try unplugging the heater for a bit and then plugging it back in, see if that helps reset the system.
If all else fails, it's best to reach out to Delonghi's customer service or maybe even a professional technician to take a look and give it a tune-up. It's not always easy to fix these things ourselves, so don't be afraid to ask for help.

whats the model and make of this thermostat. Just telling us its rounds doesnt help much. Is it a battery operated thermostsat, if so i would replace the batteries. Some round thermostat have an alarm indicating the timer has come to replace the air filters, the uv lamp, your smoke detector batteries, so on so forth

Yes, change it and beeping could stop

Make sure all hoses are clear, and filters are clean. If they are all ok restart but use different temperature. Still not working, sounds like thermostat may have problem. Call service agent.

Oven keeps beeping:
As there is no reprogramming of most control boards try this, disconnect the power and wait 30 seconds and then reconnecting the power.

If it's an "F1" fault code this generally implies an electronic oven control (EOC) failure. Disconnect the power, wait 30 seconds or longer and then reapply power. If "F1" returns upon power-up, replace the electronic oven control.
The oven control can be accessed and replaced from the rear of the control panel.

NOTE:Disconnect the power cord from the power source before removing the panel from behind the console.
If its an F2 ERROR CODE, The F2 error indicates an open circuit in the oven temperature probe.

Your range has a resettable thermostat in series with the oven temperature probe. If this thermostat opens the clock will display F2 and the oven won't heat.
You can reset the thermostat by pushing in the reset button on top of the thermostat.
Some ovens have an alarm that will beep continuously every six seconds to alert you that the oven is still on. Usually, a kitchen timer that you have set will cause the beeping, but occasionally it can be an error with the oven's settings. If it is the kitchen timer, you can simply push the "Kitchen Timer On/Off" button to end the continuous beeping. If that does not stop the beeping, it is probably beeping due to an error. You can turn the continuous beeping off but you may still need to troubleshoot the issue that is causing the beeping noise.

How to Get GE Oven to Stop Beeping eHow

It requires surgery to remove the beeper :) seriously, find a local nerd to go in, not hard to do, and yank out the little piezo buzzer. I've had customer that wanted the same, factory said sorry no dice.

Can you provide me the model number of the unit? The model number starts with 1FXX-XXX. So that i can verify if that thermostat is capable of creating a beeping sound.

Change the batteries

Maybe the horizontal IC output are damaged need to be replaced
