Updated 09/18/2018: If you
are using one of these newer stats, E055-71520316, E055-71520317, E055-71520318, or E055-71520319, you can
use the new model relay board E025-71481103.
Please note that it must be used with one of those newer stats. If you
don't have one, you would have to purchase a new stat to go with the
board. If you'd like to provide the model and serial for your current fan coils, we can also send that on to IEC to confirm what will work now.
So, we are handling each relay board order case by case to be sure that we pair the correct relay board with the your thermostat. Use the chat system, or email us your details so we can match you up correctly.
E025-71308201 has been replaced by the current model E025-71520303 which is what will be shipped.
