Product Notes
Venstar T2800 Platinum - First Listing

This listing gives you the Venstar T2800 Platinum as a new, white wall thermostat with push-button control and AA battery power. The backlit display and configurable outputs make it a strong candidate for a commercial space that needs a 7-day program. A concrete reason to choose this listing is that it includes those useful controls in a single package. The limitation is that the second listing is identical, so there's no unique benefit here beyond the base product.
Venstar T2800 Platinum - Second Listing

The second listing offers the same Venstar T2800 Platinum model, also in new condition, with the same white finish and the same control layout. It's a solid alternative if you want a second source for the same thermostat. A concrete reason to choose this listing is that you can rely on the same specification set as the first listing, so you won't lose any functionality. The limitation is that it doesn't distinguish itself in any way-no additional features or unique benefits.
Final Choice by Use Case
If your priority is a straightforward programmable thermostat for commercial use, either listing will get you the same Venstar T2800 Platinum experience at $115. The final call is a tie. Pick whichever listing feels more convenient to you, and you'll end up with the same 7-day programmable thermostat.
