In the model below, I changed the schedule of thermal zones 1 and 11 to RCB AHU_Clg_Thermostat whilst all others are RCB ACU_Clg_Thermostat and saved. However, whenver I switch to Facilty-Thermal Zone, i realise all thermostats change back to RCB ACU_Clg_Thermostat. How make the thermostats stay permanently without it reverting back.
