TH106, TL6160 Programmable Thermostat
OWNER’S GUIDE
* LP appears only for the first two minutes when the thermostat is without power. This can occur during a power outage or when the thermal protection device inside the baseboard heater is opened.
Description
This programmable thermostat can be used to control an electric heating system such as an electric baseboard heater, a radiant ceiling, a radiant floor, a convector or a fan-forced heater.
The thermostat cannot be used with:
- a resistive load over 16.7 A
- a resistive load under 2 A
- a system driven by a contactor or relay (inductive load)
- a central heating system
SUPPLIED PARTS:
- One (1) thermostat
- Two (2) 6-32 screws
- Two (2) solderless connectors
Installation
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK. THE INSTALLATION MUST BE PERFORMED BY AN ELECTRICIAN.
- All cables and connections must conform to the local electrical code.
- Special CO/ALR solderless connectors must be used when connecting with aluminum conductors.
- Install the thermostat onto an electrical box. · Install the thermostat about 5 feet high, or an inside wall facing the heater.
- Avoid locations where there are air drafts (such as the top of a staircase or an air outlet), dead air spots (such as behind a door), or direct sunlight.
- Do not install the thermostat on a wall that conceals chimney or stove pipes.
- The thermostat wires are not polarized; either wire can be connected to the load or to the power supply.
NOTE: Always keep the thermostat’s vents clean and unobstructed.
Connect the thermostat wires to the line wires and to the load wires using solderless connectors for copper wires.
- Push any excess wire back into the electrical box.
NOTE: If necessary, before re-installing the front component, configure the thermostat (see section 3). - Return power to heating system.
Connect the thermostat wires to the line wires and to the load wires using solderless connectors for copper wires.

Press and hold both and buttons simultaneously for approximately 3 seconds until the icon is displayed.
Modes of Operation
Automatic – The temperature is set according to the programmed schedule. To place the thermostat in this mode, press the Mode button until is displayed. The icons of the current period and preset temperature are also displayed.
Temporary Bypass: If you modify the setpoint (by pressing the 
or button) when the thermostat is in automatic mode, the new setpoint will be used until the end of the current period. When the next period starts, the temperature set for that period becomes the new setpoint. To cancel the bypass, press the Mode button.
Manual – The programmed schedule is not used. The temperature must be set manually. To place the thermostat in this mode:
- Press the Mode button until is displayed.
- Set the temperature using the , , or button.
Schedule
The schedule consists of 4 periods per day which represents a typical weekday. You can program the thermostat to skip the periods that do not apply to your situation. For example, you can skip periods 2 and 3 for the weekend.
| Period | Description | Setting |
 | Wake | |
 | Leave | |
 | Return | |
 | Sleep | |
The Comfort () temperature is used in periods 1 and 3 and the Economy () temperature is used in periods 2 and 4. For example, when the period changes from 1 to 2, the setpoint automatically changes from Comfort setting () to Economy setting ().
You can have a different program for each day of the week; i.e., each period can start at different time for each day of the week. The thermostat has been programmed with the following schedule.
| Period | Setting | MO | TU | WE | TH | FR | SA | SU |
| | 6:00 AM | 6:00 AM | 6:00 AM | 6:00 AM | 6:00 AM | 6:00 AM | 6:00 AM |

- Press Pgm to select another period, or press Day to select another day. Then repeat step 3.
- Press Mode to exit the programming mode.
NOTE: If no button is pressed for 60 seconds, the thermostat will automatically exit the programming mode.
Power Outage
During a power outage, LP (Low Power) appears for the first minute. Then the screen becomes blank. The settings are stored in memory. After initial installation, product must be connected to power for a minimum of two hours to enable the power outage feature. However, if the power failure exceeds 4 hours, the thermostat’s clock must be re-adjusted and, if you are using the automatic Daylight Savings Time changeover function, it must be re-enabled. When power returns, the thermostat will return to the mode of operation active prior to the power failure.

FAQs
The thermostat must be installed on an electrical box. The box should be located as close as possible to the heating element, but not directly above it.
If you mean changing the set points, you need to hold both up/down button at the same time until the display blinks. Choose Fahrenheit or Celsius, F (Fan) or Baseboard (radiant heat). After these options you set your high point and your low point. My guess is that your high point maxes out at 60 degrees. You should be able to turn it up all the way to 85. If you can’t make any changes, it sounds like the device itself may be faulty.
The backlight only came on when the buttons were pressed, and I don’t remember seeing anything in the manual about an “always on” backlight setting.
I’m not sure the model of the cadet matters. It works with both fan and radiant heat models.
I have 5 of these, will lower to 41 degrees at the least.
This unit is wired directly to your 220v 2-wire circuit for the thermostat. This is a line voltage thermostat.
This Thermostat is not to control an A/C unit, is design to control a: ( baseboard, cadet) heater. (120v/240v)
Is very simple and it works fine with that load but can not control a central heating/cooling system.
Yes it will. That is the exact application I used the thermostat for. However, during setup you must set the thermostat for fan forced air. As a safety feature, it will cycle the heater off every five minutes.
No
The screen is backlit it’s blue
Yes, the temporary bypass enables temperature override without changing programming.
It does not have an on/off switch. If you want to be sure the TH401 is unpowered, flip its circuit breaker off. You can set the temperature as low as 40°F (5°C). If that set temperature is below room temperature, the TH401 will draw only trace power, but it will still be powered.
It’s for resistive loads, not inductive. So your circulator (motor) would have to be low wattage. I don’t know how low.
Yes, max temp is preset by manufacture
Yes, it is single pole so it has 2 wires and is a great replacement for mechanical thermostats.
