Honeywell Programmable Timer HELP!


Our Honeywell 540A timer is up and running to control the front porch lights. However, the switch is very hot to the touch only when the outside lights are on. (The timer has a manual on/off and there is not heat when off) I can touch the metal screws but not for too long. There are three switches next to each other and the only one hot is for the timer. I have figured out a few things about this switch:

No CFL's
Will control total of 500 watts

I certainly do not want to burn my house down and I am wondering what should I do not. Would CFL's make the switch hot? Is there something wrong with the wiring? I do not want to pay for an electrician and am trying to troubleshoot myself. But again, I'm not stupid enough to keep this thing on until I figure out the cause and if there is any danger.

Thank you for any insight.

Does the timer have a relay or triac to turn the lights on and off?
If it makes a click sound when you turn it on then it has a relay. A relay is basically a magnetic switch.
If it is silent when it turns on/off then it probably uses a triac or some other chip that makes heat.
If it can dim lamps then it probably uses a triac, just like a dimmer switch. A triac makes heat.

That timer is only rated at 500 watts.
How many lights, and wattage of each light do you have ?

I would call the factory and see what they say. It may be normal as with dimmers.

So you're saying that that your dimmers in your house are so hot that you can't touch them for more that a few seconds ???

Some dimmers do get very hot.

The install manual says your can be used with florescent lights.

How many watts are you controlling with yours.
