How to Use This Document
The advanced installation and configuration instructions are intended to supplement the
standard installation instructions shipped with the thermostat or available for download
on www.HVACpartners.com. The advanced settings and configuration options detailed
in this document are intended for professional installers only. Incorrect configuration
may lead to improper operation and equipment damage.
Each section of this document is outlined in the following structure:

Wiring Diagrams
The following pages provide wiring diagrams for multiple heating and cooling equipment
configurations. Dual Transformer Installations
During the Guided Setup process, you will need to configure the thermostat for two
transformers. This removes the internal jumper between Rc and Rh.
NOTE: the remaining diagrams show single transformer installations for simplicity but all
can be setup for dual transformer by setting up Rc, Rh, and C as outlined in the above
diagram.
Single-Stage Furnace or Fan Coil with Single-Stage A/C
Do not jumper Rc & Rh.
This is done internally.

5 | P a g e
Two-Stage Furnace or Fan Coil with Single or Two-Stage A/C
2 Stage Heat Pump with 2 Stages of Aux Heat (Furnace or Fan Coil)
Do not jumper Rc & Rh.
This is done internally.
Do not jumper Rc & Rh.
This is done internally.

6 | P a g e
Boiler or Radiant System with Fan Coil and A/C or Heat Pump
Accessory Connection for Dehumidify Operation
*For FV fan coils, jumper J1 on fan coil board will need to be removed.
J2 will need to be removed for two-stage heating (W1, W2).
Do not jumper Rc & Rh.
This is done internally.
Do not jumper Rc & Rh.
This is done internally.

7 | P a g e
Accessory Connection with Power from Thermostat
Per the diagram above, the accessory is powered using Rh/Rc. During the Guided
Setup process, you can configure the accessory power source. When you select Yes,
the internal relay on the thermostat will close.

8 | P a g e
Accessory Connection with Self-Powered Accessory
Per the diagram above, the accessory is self-powered. During the Guided Setup
process, you can configure the accessory power source. When you select No, the
internal relay on the thermostat will open.

9 | P a g e
Single Transformer versus Dual Transformer Installations
This thermostat does not need a physical jumper wire between Rc and Rh. Software in
the thermostat allows you to configure this connection. During the Guided Setup
process you will need to specify how many transformers are connected to the
thermostat. When you select One, Rc and Rh are internally jumpered. When you select
Two, Rc and Rh require their own transformer. If you connected wires to Rh and Rc
during installation, select Two. If not, select One.
Installations without a Common (C) Wire
If your current thermostat does not have a wire connected to C, the following options
are available:
1) Repurpose the G wire as a C wire per instructions below.
2) Use a Power Extender Kit (TS-2PE01). Power Extender Kit installation
instructions for Carrier contractors are available on www.HVACpartners.com.
3) Run an additional wire from your equipment to the thermostat.
Repurposing the G wire for the C wire –Single Stage Equipment
Repurposing G wire for the C wire will result in the loss of continuous fan operation and
air circulation features of the thermostat.
WARNING! This is only recommended on single stage Gas, Oil or Propane Furnace
equipment applications with 4 wires running to the thermostat (R, W, Y, G) and Carrier
fan coils.
1) Use the G wire for the C wire at the equipment

10 | P a g e
2) Add a jumper wire from Y (or Y1) to G on the furnace board or fancoil wiring to
allow the blower to turn on during cooling operation.

3) Connect Repurposed Wire to the Thermostat
a. When you’re ready to connect the wires to your new thermostat, connect the
G wire to the C connector block on the thermostat
NOTE: there will no longer be a wire connected to the G terminal at the
thermostat.
4) Guided Setup
a. The thermostat automatically detects the wires you’ve connected
b. You will receive a warning the G wire is not connected. You must disable
Auto Detection by touching the red Override button then touch Yes.

c. Touch G to turn box green then touch Next
d. Follow standard installation instructions to complete installation.
