The White Rodgers 1E65-140 is a non-programmable electronic digital thermostat for line voltage applications, designed to control electric heating systems such as baseboard heaters, radiant floors, radiant ceilings, and convectors. It features precise temperature control with proportional band and anticipation options. Below are the key specifications, installation, operation, and troubleshooting instructions.
Assemble tools: Screwdriver, wire strippers, level. Installation should be performed by a qualified heating and air conditioning contractor or licensed electrician. If in doubt about electrical wiring, consult a professional.
Operator: Save these instructions for future use! FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
This non-programmable electronic digital thermostat is designed for line voltage applications to control electric heating systems. It provides precise temperature control with options for proportional control and anticipation based on load size.
Key features: Digital display, backlight, setpoint adjustment via UP/DOWN buttons, switch for HEAT/OFF, installer configuration menu.
CAUTION! 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.
WARNING! All wiring must conform to local and national electrical codes and ordinances. Use with copper conductors only. Use wire connectors approved for 12 AWG only. Keep the air vents of the thermostat clean and unobstructed at all times. Failure to do so can cause harm to your thermostat.
Do not exceed the specified ratings. Higher loads will damage control and could cause shock or fire hazard.
Disconnect power at main fuse or circuit breaker. 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 affix the wall plate to the electrical junction box using two 6-32 flat head screws included with the plate.
Make the appropriate connections to the thermostat as per wiring diagrams. The wires are non-polarized so either wire can be connected to either terminal.
4-Wire Installation
Connect two hot wires to the L1 terminals and two load wires to the LOAD terminals. Suitable for 240 VAC systems.
2-Wire Installation
Connect one hot wire to L1 and one load wire to LOAD. Suitable for 120 VAC systems.
CAUTION! Use copper conductors only. Tighten screws securely.
Slide thermostat switch to "HEAT" 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 "UP" or "DOWN" button once. The icon appears and the thermostat displays the setpoint temperature.
To change the setpoint, press the "UP" or "DOWN" button to raise or lower the temperature until the desired setpoint is reached.
To turn the backlight on, press the "LIGHT" button, or the "UP" or "DOWN" button once.
To suspend the thermostat operation, slide the thermostat switch to the "OFF" position. In this position, the thermostat still has power but the display is turned off.
To reset the thermostat, press the "UP", "DOWN", and "LIGHT" buttons simultaneously.
To change the thermostat installer configuration, press and hold the "LIGHT" button for 5 seconds. The features and (defaults) are selected by pressing the "UP" or "DOWN" button once to scan the installer configuration selections. The defaults are changed with the "UP" or "DOWN" button.
| Feature | 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 baseboard 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 configuration selections permanently, even after power outages.
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.
If issues persist, contact a qualified service technician.
