Hi @control - Yes you can set a range. Your Nest thermostat gives you a temperature range that you can select from when you set an Eco Temperature. The Eco Temperature ranges you can choose from are large: 40-70 °F (4-21 °C) for heating mode and 76-90 °F (24-32 °C) for cooling mode.
Hope this helps!
I am glad to hear you were able to resolve the issue you were having. I wanted to check in with you, and see if you had any further questions from here. Please let me know, as I would be happy to take a closer look.
We know this item is temperature control on and off, I used to ask how much power it can withstand, no one can answer, now I ask if it can be used to control this (Zone Valves) His power is relatively high
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
