INSTALLATION
This thermostat has been designed to control a RESISTIVE load
not exceeding 3500 W @ 240 VAC or 1750 W @ 120 VAC, such as
electric baseboards, convectors, radiant ceilings, floor heating systems, etc.
It is not compatible with a low voltage controller used by a central heating system or systems using a contactor or a relay
whose current is under 2 A.
TURN OFF POWER TO THE HEATING SYSTEM AT THE
MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.
Installation should be carried out by an electrician.
This thermostat is designed to be used with a self-protected heating system equipped with linear limit control
and circuit breaker.
For a new installation, choose a location about 5 ft. (1.5 m)
above the floor, facing the heating system and on an inside
wall.
Avoid locations where there are air drafts (top of staircase, air
outlet), dead air spots (behind a door), direct sunlight or concealed chimneys or stove pipes.
All cables and connections must conform to the local electrical
code.
Special CO/ALR solderless connectors must be used when
connecting with aluminum conductors.
The wires are not polarized, therefore the connections can be
made on either terminal.

To view the ambient temperature,
peel the lower-right section of the
sticker and remove it from the display.
When you first power on the
thermostat, the display

ambient temperature and the MANual
mode is selected (framed). The
default setpoint is preset to 20°C.
To change the time display format from 12 to

Temperature control type
The TH104 is factory-set to use the proportional temperature control type (15-second cycles).
Since this temperature control type uses a fast commutation rate, it
is not compatible with fan-equipped systems. Also, it can also cause
light flickering, especially in rural regions.
If you have a fan-equipped system, use the conventional temperature control type (15-minute cycles). To change the type:
Press and maintain , do not release.
Reset the thermostat using a pointed object (e.g. paperclip).
Release the button.
Following the change, the FAN indicator is displayed on the screen.
To revert to proportional control, repeat above steps.

Protected memory
During a power failure, all programs are protected. The thermostat
display remains on for approximately 15 minutes after which the LP

power failure exceeds 6 hours. The thermostat will automatically
return to the previous mode when power returns.
