Question Electric Baseboard Thermostats

Hi all,

I am in the process of ordering new electric baseboard line voltage thermostats for my house. The old ones really date the house and make it look ancient. The present ones are Honeywell T498A.

At any rate, I want to replace them with a different model - either T410A1013 or T410B1004. The only difference between the two is that one has a SPTS and the other has a DPTS inside.

I have 240 V lines to the heaters, and both models are rated for 120 and 240 V and 2 or 4 wire applications. Does the switch type make a big difference?

You need a "2-pole" device, one that will switch the 2 "Line wires" to the 2 "Load wires". Obviously, this is either a 4-lead device, or a 4-terminal device.

You must positively indentify the 2 "Line-connection" leads/terminals. Once you have eliminated these 2, the other 2 are the "Load" connection.

Good Luck, & Learn & Enjoy from the Experience!!!!!!!
