Precautionary measures
OFF
OFF
Hint: Your system should not make any noise and you should not feel any air
exiting your vents when the power is OFF.
•
Read all instructions carefully before starting the installation.
•
Before installing the Thermostat, be sure to turn off the power for your HVAC system either at the
Circuit Breaker Box or at the Main Switch.
•
Leave the power OFF until you have finished the installation.

10
• Remove the front cover of your old thermostat from its base.
•
Your system is not compatible with the TrickleStar Thermostat if you see:
- thick black wires with wire nuts.
- the base on the old thermostat has “L1” and “L2” on the terminal blocks.
- “120 - 240 V AC” or “High Voltage” labels.
•
The TrickleStar Thermostat is ONLY designed for 24 V AC with a total switching current of 3 A
maximum.

Let’s get started!
After removing the front cover of your old thermostat from its base, we recommend that you take a
photo of the wires connected to the terminals at the base.
You may need to refer to this photo at a
later stage.
Before you start the installation, we recommend that you take a photo of the label attached at the
bottom of your
Thermostat. You may need to refer to this information when you connect your
Thermostat to Wi-Fi via the
TrickleStar Portal.

12
With or without C-Wire?
The
TrickleStar Thermostat supports installation for both with and without C-Wire, but the installation is
a little dif
ferent.
Do you have a C-Wire connected to your old thermostat? Check the wires connected to the terminals
on the base of your old thermostat.
• If a wire is connected to the “C” terminal, then your system has a C-Wire to power your new
TrickleStar Thermostat.
• If there is no wire connected to the “C” terminal, then you need to install a C-Wire Adapter to
power your new TrickleStar Thermostat.

Yes, with C-Wire.
Continue to page 13.
No, without C-Wire.
Continue to page 26.
Note: Make sure that the C-Wire at your old thermostat is directly connected to the HVAC
Control Board.

Installation With a C-Wire
If your system has a C-Wire, it will power your new
TrickleStar Thermostat.
You do not need a C-Wire Adapter (sold separately as an
accessory).
Step 1: Disconnect and label old thermostat
wires
Disconnect and label the wires from your old thermostat
carefully, one wire at a time, using the wire labels
provided.
Make sure the wires do not fall back into the wall when
released from the terminals and that the labels are
fastened to the wires securely.
Note: Make sure that the C-Wire at your old thermostat is directly connected to the HVAC
Control Board.

14
Step 2: Remove old jumper wire
If the terminals on your old thermostat has a jumper wire between RH, RC or R, remove the jumper
wire.
Your new TrickleStar Thermostat does not need this jumper wire.

Step 3: Unscrew old Mounting Plate
Unscrew the Mounting Plate of your old thermostat to remove it from the wall. When you remove the
Mounting Plate, be sure not to tear of
f the labels on the wires.

16
Step 4: Replace with new Thermostat Mounting Plate
Decide if you want to mount the
TrickleStar Thermostat directly to the wall or you want to use the Trim
Plate.
The Trim Plate helps you to hide marks or holes left on the wall by your old thermostat.
