How do I compare two temperatures

[malc-c]

You beat me to it.

I use a similar process for monitoring the temperatures in my Vivariums, and sounding an alarm if they exceed a set range. Basically

IF Temperature >  alarmhigh  then AlarmPin = 1
IF Temperature <  alarmlow  then AlarmPin = 1

The variables used are word type so in my code for the thermostat 23.6C would be stored as 236. Likewise a high threshold would be 350 (35.0c)

IF Temperature > alarmhigh then AlarmPin = 1
IF Temperature < alarmlow then AlarmPin = 1

Malcom, you have a typo in your two lines of code!
