Settings

User settings

These settings are basic things within the thermostat concerned with preference and user interaction. They involve the lockout local changes, temperature limits, and how the thermostat responds to heating/cooling needs.

• Display ON (ADC-T2000 only): The thermostat mode and temperature is displayed at all times when this feature is enabled. (1.5 FW+ only)
• Display Options (ADC-T3000 only): Adjust what the thermostat displays on the main screen.
  • Simple mode just displays the current temperature along with the mode (e.g., cooling, heating, auto) and setpoint.
  • Humidity mode displays the current humidity percentage below the temperature.
    
    Note: Humidity display is not supported when in Celsius mode.
     
• Heat/Cool Setpoint: The allowed range for the Target Temps in Heat and Cool modes.
• Overshoot: The number of degrees beyond the Target Temp the system heats or cools before shutting off. (Recommend leaving this at 0 for comfort and efficiency reasons)
• Swing: The number of degrees, above and below the Target Temp, the HVAC system comes on to cool or heat, preventing wear on the system components due to excessive cycles.
• Thermostat Lock:
  • Partial: Allows Temp Changes but not Mode. This functionally disables the mode button.
  • Enabled: Locks all local changes. This disables all buttons, so even if it's in off mode the user is not able to locally check the firmware version.
• Motion Sensor (ADC-T3000 only):
  • This setting will enable the thermostat screen to wake when motion is detected nearby.
  • This feature is only available if the thermostat is AC powered.

Advanced settings

These settings involve how the thermostat runs the various heating and cooling cycles.

Important: Leave proper delays and off times to prevent the system from overheating or causing unnecessary wear and tear.

• Balance Point: The outdoor temperature at which the heat pump stops running and only use Aux heat.
• Calibration Temperature: Used to adjust the ambient room temperature reading up or down to a more accurate value. This may be necessary if the thermostat is installed in a location with abnormal temperature conditions, such as in direct sunlight or on a wall adjacent to an unheated room.
• Cooling Differential: The number of degrees above the Target Temp the Ambient Temp can raise before activating the next stay of cooling. This works in conjunction with Staging Delay.
• Compressor Delay: The amount of time the compressor waits to turn on to prevent damage from excessive cycling. Each time the compressor is turned on, the pressure is built inside. This pressure must be equalized once it is turned off before it can be cycled on again.
• Fan Circulation Period: The amount of time the fan is in circulation. This feature works with Fan Duty Cycle to determine how long the fan is on during this time.
• Fan Duty Cycle: The percentage of the circulation period the fan is on. For example, if the circulation time is 20 minutes, and the duty cycle is 25%, the fan is on for 5 minutes, then off for 15 minutes until the next cycle.
• Enable Fan ON Control: When enabled, allows the customer to select 'Indefinite' under fan options through the thermostat UI. This runs the fan continuously until deactivated.
• Fan Purge: The amount of time the fan remains on to clear the air ducts after the system is turned off. It's a good idea to keep this around 1 minute or higher in order to ensure any leftover warm or cold air is moved into the house and not wasted.
• Heat/Cool Staging Delay: The amount of time the heating or cooling activates the next stage of heating or cooling if the setpoint has not been reached.
• Heating Differential: The number of degrees below the Target Temp the Ambient Temp can drop before activating the next stage of heating. This works in conjunction with Staging Delay.
• Heat Pump Expiration: Amount of time the heat pump runs for without reaching the target setpoint.
• Humidity Differential: The number of degrees below the Temperature Setpoint that the AC is allowed to cool in order to reduce humidity to the desired setpoint. For example, if the temperature setpoint is 72˚F, the Humidity Setpoint is 80%, and the Humidity Differential is 3˚F and it is currently 72˚F with a humidity of 90%, the AC will continue to run until either the humidity reaches 80% or the temperature reaches 69˚F.
• Humidify While Heating (ADC-T3000 only): When enabled, the humidifier will only run while the heat is also running when in heat or auto mode. When disabled, the humidifier will run any time the humidity levels drop below the humidity setpoint.
• (Pump) Staging Delay: The amount of time allowed for the Ambient Temp to be above or below the Target Temp before the next heating or cooling stage kicks in. This works in conjunction with Heating and Cooling Differentials.
• Recovery Setting: This determines how the system behaves if it has multiple stages. If it had to trigger a secondary stage to heat or cool the home as it gets closer to the target Economy turns off those stages and Comfort Keeps them on until the target is reached.
• Run Fan with Aux Heat: If the system is a Heat Pump this determines if the G wire is active during Aux Heat. It is not advised to change this setting.

Installer settings

These determine how the thermostat controls the HVAC system.

Caution: Making incorrect changes to these settings can cause catastrophic system failures.

• Cool Stages: Determines the number of condenser stages the system has.
• Configurable Z Terminals:
  • W3 (Normal: 3rd stage heat, Heat Pump: 3rd Aux Stage)
  • Humidity
  • O/B Zoning (Normal: Master thermostat control, Heat Pump: O and B both used with B going into the Z terminal)
• Heat Type:
  • Electric is used for heating systems that require the thermostat to turn on the fan.
    • Examples: Forced Air Heating Systems, generally any electric based heating sources, most Heat Pumps
  • Fossil (e.g. gas, oil) is used for heating systems that don't require the thermostat to turn on the fan. This is a little misleading since this is not strictly for fossil fuel powered systems, but the terminology is industry standard. 
    • Examples: Hydronic heating (radiators), baseboard heating, Dual Fuel heat pumps, any furnace that turns on the fan without relying on the thermostat (common with fossil fuel furnaces that have a heating delay built in so that the system doesn't blow around cold air at first), Radiant floor heating
• Heat/Cool Stages: Determines the number of heat stages present in the house for Normal. For Heat Pump, it is the number of Aux/Emergency stages.
• Heat Pump/Aux Stages: Determines the number of pump and auxiliary heat stages present on the system.
• HVAC Type: This primarily determines how the thermostat distributes calls for heat.
• O/B Terminal:
  • Normal: Master thermostat control
  • Heat Pump: O and B wire Selection
• Wiring Configuration: Displays any available wiring configuration information.

Remove or restore the setup wizard for the ADC-T2000

The setup wizard is available using the Customer Website or app after the thermostat has been enrolled in the Z-Wave network. The wizard allows the user to select the wires that are connected and configure the settings for the thermostat. The setup wizard for the ADC-T2000 can be removed from and restored to the Customer Website and app using the Partner Portal or MobileTech app.

Frequently asked questions

Is an Alarm.com account required to use the Smart Thermostat? 

An Alarm.com account is required to configure the ADC-T2000 for the first time. Initial configuration can be done through the customer wizard either on the Alarm.com Customer Website or app. The ADC-T3000 can configure additional options locally. This can also be done on the Partner Portal or MobileTech app.

If a customer later cancels service, the Smart Thermostat continues to function, and the customer retains basic control of heat and cool modes as well as the target temperature. However, all advanced features and capabilities (such as Smart Thermostat scheduling and Away from Home overrides) is lost. 

Which settings can be changed on the Customer Website?

Only the Basic settings are accessible through the Customer Website. All other settings can be modified using the Partner Portal.

The first time a customer logs in through the Customer Website after a thermostat is installed, they'll be shown an installation wizard which will allow them to select their HVAC type and wires, which automatically configures the Installer settings for them.

How does the user set up thermostat schedules? 

Thermostat schedules are set up using either the Customer Website or app. For more information about setting up thermostat schedules, see Configure Thermostat Schedules. 

The heat pump heats when it’s supposed to be cooling. Why is this happening?

Heat pumps have either an O terminal or a B terminal. When configuring the Smart Thermostat, it prompts to select which terminal type the heat pump has. If the system heats when it’s supposed to be cooling, this means that the incorrect terminal type was selected at configuration.

This setting can be updated when configuring the device using either the Partner Portal or MobileTech app in the Installer tab. When Heat Pump is selected as the HVAC Type, the option to select the O or B terminal appears on the configuration page. 

Why aren't all the settings visible on every system?

Depending on the HVAC system, not all settings are needed. This is why configuring the Installer settings correctly is very important. Those settings determine what options are shown on the other pages.
