Spoke with Wan, issue was the thermostats were jumping all over the place during the day and night. All four thermostats are programmable with schedules. They’re Pro6000 thermostats, can’t disable program so set all four to the temps Wan desired. From here temps can be adjusted manually, just need to use hold button. All thermostats would need to be replaced to go completely away from all programming functions, cannot be disabled on this style of thermostat
