************** Rick, Your call on billing Arrived and he said it works now I applied labor, remove if desired. **************** Arrived and Frank relayed to me that the thermostat returned to normal function after being reset this morning. He offered to show me the building management system. I did take a look at it to confirm the temp split and that the unit was not producing an error.the thermostat was responsive and the space it controls was cooling Thank you, Jon
