Unable to Install 2441ZTH

[jam10]

I have tried several times to install my 2441ZTH. Each time I get the following error: "Cannot determine Insteon Engine." Any suggestions? Thanks

If you are not using an external power supply and are using batteries.

Did you wake it up first with the set button?

Battery devices go into a power saving mode and will not respond until it is woken up.

Thanks for the advice. I added the 5v AC adapter and was able to program the 2441ZTH into my ISY-994. Unfortunately I did not realize the external temp from the probe does not report back to admin console or iPhone/iPad apps. I have the external probe dropped inside our pool and was hoping to control the pool heater (220v Load Controller device) with the wireless 2441ZTH, but even though the external temp shows on the device screen (very, very small numbers at center top) I cannot create any program commands based on the external probe temp (water temp).

 

Am wondering if anyone has any ideas to accomplish the above with another Insteon device used in conjunction with my pool heater load controller and ISY-994. Currently I have the pool heater linked to an On/Off keypad inside the house allowing me to manually turn on/off or crete an hourly program, but was hoping I could do this all with a temp variable.

If you want to only use the external probe and most likely void the warranty

Here is a thread where the internal sensor was replaced by the external probe for testing a ponds temperature.
