Emerson 1E65-144 Line Voltage Digital Thermostats

DESCRIPTION

Operator: Save these instructions for future use! 
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:
One (1) thermostat
Two (2) 6-32 pan head screws

Available Accessories:
F61-2642 Adapter Plate

  500 W @ 240 VAC
  250 W @ 120 VAC
• Maximum load: 16.7 A (resistive only)
  4000 W @ 240 VAC
  2000 W @ 120 VAC
• Setpoint range: 7°C to 32°C (45°F to 90°F)
• Display range: 0°C to 37°C (32°F to 99°F)
• Display resolution: 0.1°C (1°F)

PRECAUTIONS

WARNING

• 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.
• 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.

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.

NOTE Use with copper conductors only. Use wire con-nectors approved for 12 AWG only.
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.

CAUTION Keep the air vents of the thermostat clean and unobstruct-ed 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.

OPERATION

Slide thermostat switch toposition. 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:

To view the setpoint temperature, press the button once. The icon appears and the thermostat displays the setpoint temperature. To change the setpoint, press the button to raise or lower the temperature until the desired setpoint is reached.

To turn the backlight on, press the button, or the 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 to the following table for the selections of your choice.)

	Default	Options
Backlight	LO (On)	LF (Off)
Display Reading Adjustment*	H0.0	L3.0 to H3.0
Proportional Control**	PO (On)	PF (Off)
Anticipation***	AL(2000-4000 W)	AS (500-2000 W)
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 gu-ration selections permanently, even after power outages.

• To reset the thermostat, press the and buttons 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.

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.
