Question

Give 10 Test Scenarios for a Smart Thermostat?

Answer 1

The following are the 10 test scenarios for a smart Thermostat:

Thermostat Response test:

1.Set room temperature to a steady state temperature of 70° F. Room temperature should remain constant within ±1° F. Once steady state is reached, begin logging room temperatures and contactor state. Log at 70° F steady state for 15 minutes.

2.Set device temperature “Cooling” set point to 2° F above recorded room temperature (72° F). All system contactors should remain open at this time.

Thermostat temperature setting test:

1.Set room temperature to a steady state temperature (e.g. 68° F). Room temperature should remain constant within ±1° F.

2.Initiate a cooling setting by placing device in “Cooling” mode (on device screen).

Expected Outcome:Indication is given that the device is switched into “Cooling” mode after manual switch.

3.Set device temperature “Cooling” set point above room temperature (on device screen) to confirm device inactivity (e.g. 70° F).

Expected Outcome:Indication is given that the device has changed “Cooling” set point to the appropriate value. No event should occur at this point.

4.Initiate a cooling event by placing device set point temperature (on device screen) below the room steady state temperature (e.g. 66° F).

Expected Outcome:During “Cooling” event, contactors close for the compressor and blower.

5.Return device temperature “Cooling” set point (on device screen) to above room steady state temperature (e.g. 70° F) to end cooling event.

Expected Outcome:The compressor and blower contactors open after change of “Cooling” set point to above room temperature.

6.Initiate a heating setting by placing device in “Heating” mode (on device screen).

Expected Outcome:Indication is given that the device is switched into “Heating” mode after manual switch.

7.Set device temperature “Heating” set point below room temperature (on device screen) to confirm device inactivity (e.g. 66° F).

Expected Outcome:Indication is given that the device has changed temperature set point to the appropriate value. No event should occur at this point.

8.Initiate a heating event by placing device “Heating” set point temperature (on device screen) above the room steady state temperature (e.g. 70° F).

Expected Outcome:During heating event, contactors close for the heater.

9.Return device temperature “Heating” set point (on device screen) to below room steady state temperature (e.g. 70° F) to end “Heating” event.

Expected Outcome:The heater contactor opens after change of set point to room temperature.
