Alert that max temp cannot equal min temp, but value will remain regardless

[Paucey]

If the user selects a max temp that equals the current min temp they will be shown an alert that tells them that max temp must be greater than the min temp.

Despite this alert, however, the selected (equal to the min temp) value will still remain as the selected max temp.

Steps to Reproduce:

Set a minimum temperature.
Attempt to set the max temperature to the same value as the minimum.
Alert message should appear.
After alert message is closed, the maximum temperature remains set to the presumably invalid value.

Suggested fix:

Remove the alert message (if max temperature can = minimum temperature without issue)

or,

Alter the max temp options to show only values > min temp (rather than the current >= min temp)
