If you're experiencing too many onsite changes, you can restrict access to your thermostats. There are a few options to consider:

1. Physical Locking Covers: These are external covers or cages that fit over the thermostat and are secured with a lock and key.

2. Digital Locking: Some modern thermostats feature digital locking mechanisms that require a password or PIN code to access or modify temperature settings.

Sometimes, you don't want to lock everyone out if changes need to be made. This guide will walk you through the digital locking options on your thermostats.

Range Stop (Temperature). Set the minimum and maximum cool/heat temperature set points. This allows for onsite changes within a defined temperature range.

This option allows for some flexibility in thermostat controls. It pairs nicely with David Energy's "Auto-Reset" functionality, which when enabled resets local changes to recommended setpoints at close of business daily.

Follow the instructions below for setup:
