Air-Source Heat Pump:
Choose Air-Source Heat Pump if you have an outdoor compressor.
Ground-Source Heat Pump:
Choose Ground-Source Heat Pump if you have pipes connecting your system
to the ground or through walls.
Verify wiring with the photo shot before installation. Proceed with the
setup if correct. If not, check and secure the wires, then adjust connec-
tions.
5. Screen Configuration
1. Select Heat Pump Type
5.1 Heat Pump System
16
Select "On Cool" or "On Heat" based on your heat pump user manual. If
unsure, start with "On Cool." Switch to "On Heat" if cooling occurs during
heating in Settings.
Note: This adjustment is safe for your equipment.
2. Set Reversing Valve Mode
Select "Yes" or "No" based on your auxiliary heat source. Choose "Yes" if
your auxiliary heating uses electricity; "No" if it uses oil, natural gas, or
propane.
Warning: For simultaneous operation, the heat pump condenser must be
installed before the auxiliary heat source to prevent device damage. If this is
not the case, select "No."
3. Heat Pump & Aux Heating Setup
17
Enable fans to run simultaneously if Aux is from a Heat Pump or Furnace. Do
not enable if Aux is from a Boiler. Choose "Yes" if both systems are used or if
uncertain.
4. Fan Operation Setup
An air-to-air heat pump loses eiciency as outdoor temperatures drop. Set
the minimum temperature at which the heat pump will switch o and use
auxiliary heat. For optimal settings, refer to your HVAC manual.

1. Temperature Settings
24
If set to 35°F (1.7°C), the heat pump won’t run below this
temperature; only auxiliary heat will be used.
The compressor stays off for a minimum of 5 minutes
between cycles. This prevents short cycling and potential
damage. We recommend keeping this setting at 5
minutes.
If set to 68°F (20°C), auxiliary heat won’t run above this
temperature; only the heat pump will be used.

7. More product introductions about Thermostat Hub W200
1.To control this accessory, the latest version of iOS or iPadOS is recom-
mended. Clean Energy Guidance requires an iPhone or iPad running
soware version 26 or later and Adaptive Temperature requires all members
of the Home app must be using an iPhone or Apple Watch running soware
version 26 or later. A home hub, such as Apple TV or HomePod, running
soware version 26 or later is required to enable Adaptive Temperature.
Location services must be enabled for the Home app and Home system
services. Clean Energy Guidance is only available within the contiguous
United States.
2.Use of the Works with Apple Home badge means that an accessory has
been designed to work specifically with the technology identified in the
badge and has been certified by the developer to meet Apple performance
standards. Apple is not responsible for the operation of this device or its
compliance with safety and regulatory standards.
3.Adaptive Temperature: Adaptive Temperature sets your Thermostat Hub
W200 to automatically adjust the temperature when you’re on your way
home, when you go to sleep, or when you’re away for an extended period of
time. Your iPhone uses on-device intelligence to predict when you’re on your
way home and adjusts the temperature so it’s just right by the time you get
there, as well as to save energy when you’re far away from home. Using the
Apple Home app on your iPhone, iPad, or Mac, you can enable Adaptive
Temperature on Thermostat Hub W200 to set the temperature using
on-device intelligence.
4.Clean Energy Guidance: Clean Energy Guidance from Apple provides a grid
forecast to help people choose when to use electricity. This forecast is
personalized for each person’s Home location and based on various
environmental and grid inputs, and identifies the times when there’s
relatively cleaner electricity on the grid. A person’s electricity rate plan
information is also incorporated when they have connected to their utility
account in the Apple Home app.
