This is how to lock the screen on the Honeywell T5 Smart Thermostat. This prevents anyone without the PIN code from changing the temperature from the Honeywell T5. I lock the T5’s screen because I have temperature schedules defined within the Honeywell App. That optimizes my energy savings. Continuously adjusting the temperature from the T5’s display would defeat the value add of having a smart thermostat. #Honeywell #T5 #Howto #SmartThermostat
