Dual set point on 308

I recently purchased a 308wifi to control a seasonal green house. I really like the controller but feel I’m either missing something, or maybe the software is. I’d like to be able to establish a low temp set point (turn heat on) and a high temp set point (turn exhaust fan on). I’d like to be able to do this but at the same time have each set point only engage the heater or fan to bring the temperature up, or down, by a few degrees and not bring it to the set point itself. For example when it now hits heating it brings the temperature down up to 20 degrees, I’d like it to only bring it up a few degrees above my low. I’m not sure if I I explained that well

I suspect the unit is able to do this through programming if it’s not already able to.

Hello,
It doesn’t seem to meet your needs :thinking:. The ITC-308-WIFI maintains a temperature range through a heater and a cooler, and the shut-off value (target temperature) for heating and cooling is the same. In other words, heating and cooling will only shut off after the target temperature is reached.
