DESCRIPTION
The 1E65-144 thermostat has been designed to control electric heating
systems such as baseboard heaters, radiant fl oors, radiant ceilings
and convectors.
The adapter plate is used to offset the thermostat when an obstruction
prevents the thermostat from being mounted directly to the junction
box.
The thermostat cannot be used with the following:
- a resistive load under 2 A
- a resistive load over 16.7 A
- systems driven by a contactor or a relay (inductive load)
- central heating systems
Parts Supplied: Available Accessories:
One (1) thermostat F61-2642 Adapter Plate
Two (2) 6-32 pan head screws

PRECAUTIONS
WARNING
!
* Failure to read and follow all instructions carefully before
installing or operating this control could cause personal injury
and/or property damage.
* All wiring must conform to local and national electrical
codes and ordinances.
INSTALLATION
Installation should be done by a qualifi ed heating and air conditioning
contractor or licensed electrician.
Loosen the screw holding the thermostat cover to the base, open cover
on hinge and remove the cover.
Screw
* To prevent electrical shock, personal injury, and/or equipment
damage, disconnect electric power to system at main fuse or
circuit breaker box prior to installation or service.
Optional: Use the adapter plate accessory if you need to offset the
mounting holes on the junction box. Align and affi x the wall plate to
the electrical junction box using two 6-32 fl at head screws included
with the plate.

INSTALLATION (cont.)
NOTE
Make the appropriate connections to the thermostat as per diagram
below. The wires are non-polarized so either wire can be connected
to either terminal.
Use with copper conductors only. Use wire connectors approved for 12 AWG only.
2 Wire Installation
OPERATION
Slide thermostat switch to position. The thermostat normally displays
the actual ambient temperature.
The thermostat displays the percentage of power usage (in "PC" mode
only) required to maintain the desired temperature. For example:
100% power usage
70% power usage
30% power usage
To view the setpoint temperature, press the or button once. The
icon appears and the thermostat displays the setpoint temperature.
To change the setpoint, press the
temperature until the desired setpoint is reached.
or button to raise or lower the
CAUTION
Keep the air vents of the thermostat clean and unobstructed at all times. Failure to do so can cause harm to your
thermostat.
Align and affi x the base to the electrical junction box or the optional
adapter plate using two 6-32 pan head screws.
Place the thermostat cover back onto the base hinge and close cover.
Install screw to secure cover.
Default Options
Backlight LO (On) LF (Off)
Display Reading Adjustment* H0.0 L3.0 to H3.0
Proportional Control** PO (On) PF (Off)
Anticipation***
Temperature Scale SC (Celsius) SF (Fahrenheit)
* Adjusts room temperature display higher or lower to agree with a
previous thermostat.
** Proportional Control allows the thermostat to modulate depending
on power usage.
***Adjusts your thermostat anticipation based on the room and base-
board heater size, e.g., in a room with a 3500 W baseboard heater,
set your thermostat anticipation to AL.
The thermostat will save the setpoint temperature and installer confi guration selections permanently, even after power outages.
To reset the thermostat, press the
simultaneously.
To suspend the thermostat operation, slide the thermostat switch to
the position. In this position, the thermostat still has power but the
display is turned off.

To turn the backlight on, press the button, or the or button
once.
To change the thermostat installer confi guration, press and hold the
button for 5 seconds. The features and (defaults) are selected by
pressing the button once to scan the installer confi guration selections. The defaults are changed with the or button. (Please refer

Heating Element Thermal Protection
Most heating elements have a protection device that activates when
overheated. It is possible that if the device is worn out, it becomes
more sensitive. This device has a chance of being activated when
the heating element is on for a long period of time. When the thermal
protection is activated, the electrical power ceases to supply the
thermostat, and its display is turned off for a few minutes. The same
phenomenon exists with a mechanical thermostat but nothing could
indicate it. A thermal protection that opens too often can cause the
thermostat to poorly regulate temperature and should be replaced by
an electrician or the heating element manufacturer.
