n 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, etc.
The thermostat cannot be used with the following:
•a resistive load greater than 16.7 A
•a resistive load less than 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
o 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, on 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.
n
oConnect the thermostat wires to the line wires and to the load wires using solderless connectors for copper wires.
2-wire installation
4-wire installation
p Push any excess wire back into the electrical box.
qBefore installing the TH106 thermostat base, install provided adapter plate (U-shaped) on 347V electrical box which is bigger than regular electrical boxes.
NOTE: If necessary, before re-installing the front component, configure the thermostat (see section 3).

a.Early Start can be used in Automatic mode only. When this function is enabled, the thermostat calculates the optimal time to start heating in order to obtain the desired temperature by the set time. The thermostat re-assesses the start time daily based on the previous day’s performance.
b.If you change the temperature display format, the preset temperatures (
, 
and 
) will return to their default settings.
c.15-second cycles should be selected in most cases as it provides better temperature control. 15-minute cycles must be selected if you have a fan-equipped heater or if 15-second cycles causes light flickering (especially in rural regions).
q Power-up
Upon power-up, the thermostat is in manual mode (
) and displays the actual (ambient) temperature.
n Press the Hour and Min buttons to set the thermostat’s clock. o Press the Day button to set the day.
r Temperature Setting
Setpoint
The thermostat normally displays the actual temperature. To view the setpoint, press the 
or 
button briefly. The setpoint will appear for the next 5 seconds.
To change the setpoint, press the 
or 
button until the desired temperature is displayed. To scroll faster, hold the button.

button respectively. The corresponding icon will be displayed.
•To use the Vacation temperature, press both 
and 
buttons simultaneously. The 
icon will be displayed.
Storing a preset temperature

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.
Manual - The programmed schedule is not used. The temperature must be set manually. To place the thermostat in this mode:
n Press Mode until 
is displayed.
o Set the temperature using the 
, 
, 
or 
button.
t 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.

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.
