First comes the invitation

We create your portal account at your request or by arrangement with your contact person at ISOTHERM. Right after that we e-mail you an invitation “New account on the Isotherm Portal”, which looks like this. Can’t find it in your inbox? Please check your junk folder too.

  1. Step 1: Set your password First time only

    In the invitation click “Set password”. On the page that opens, enter your e-mail, your new password twice and click “Save password”.

    The password must have at least 8 characters, a lowercase and an uppercase letter and a digit.

  2. Step 2: Enter your e-mail and password

    Open isothermtest.grenadecastle.com, fill in your e-mail and password and click “Log in”.
  3. Step 3: Type in the code from the e-mail

    On a new computer or phone we will send you an e-mail with a 4-digit code. Type it into the boxes — it is checked automatically after the last digit.
  4. Step 4: Done

    You are logged in. Next time you will not need a code in this browser.

Not working?

I forgot my password

On the login page click “Forgotten password” and enter your e-mail. You will receive a link to set a new password.

The link in the e-mail does not work

The link to set your password is valid for 30 days and can be used only once. Request a new one via “Forgotten password”.

The e-mail with the code did not arrive

Check your junk (spam) folder. On the code page you can click “Send new code”.

The code is rejected as “not valid”

Use the code from the most recent e-mail — older codes expire. After 5 wrong attempts you have to wait 60 minutes.

I do not have login details

Get in touch with your contact person at ISOTHERM. Once agreed, we will create your account and e-mail you an invitation.
