The TE86S Thermostat provides universal replacement of single-stage, 24Vac (20 mA to 1.5A) thermostats used in electric, gas, and oil heating and cooling systems. This thermostat is mercury free and requires no batteries. The thermostat also can be used to control single stage heat pumps. The TE86S uses advanced proportional plus integral (P+I) control for optimum temperature control and comfort.

Read these instructions thoroughly before installing product. Failure to follow these instructions could damage the product or cause a hazardous condition. Check the voltage and current ratings on the product to ensure that it is suitable for your application. Installer must be a trained, experienced service technician. Check product for proper operation after installation
Mounting Location.
Mount the thermostat approximately 5 ft. (1.5m) above the floor in a location that is free from direct sunlight, heat from appliances, hot or cold air from ducts, concealed pipes and chimneys, and drafts or dead spots behind doors or in corners. Do not mount on exterior wall, if possible. Failure to locate thermostat mounting as indicated will result in poor temperature control.
NOTE: Level thermostat mounting is for appearance only and is not required for proper thermostat operation.
Mounting Thermostat
Take out the back plate by removing the locking screw (if any) at the bottom of the thermostat. Use flat head screw driver to unlock the snaps. Lift and pull it up to remove back plate.
Using back plate as a guide, mark two mountingholes on the wall. Drill two mounting holes. Place anchors (provided) into the holes until flush with the hole. Position back plate on the wall and thread the wires from the heating and cooling equipment through the wiring hole. Holding the back plate in place on the wall, secure it to the wall using mounting screws (provided).
Wiring
Pull the connector from the back of thermostat by inserting screw driver at the base of connector and gently lift up
Color-coded 18-22 gauge wire is recommended for wiring. All wiring must follow local electrical code located near each terminal.
HEAT PUMP WITH HEAT ACTIVE REVERSING VALVE
HEAT PUMP WITH COOL ACTIVE REVERSING VALVE
Loosen the terminal screw, strip the wire and connect the wire as shown in fig 7. Firmly tighten terminal screw when finished
Set-up switch (E/F)
Failure to set the set-up switch to the E position when electric resistance heat is used may result in the overheating of the electric heater elements due to improper fan operation. The set-up switch is an internal switch (E,F) located near the wiring terminals. It is used to select proper fan operation for the heating system being used.
Place the terminal back to the thermostat, make sure it has the same orientation like in the picture described at the back. Snap the thermostat to its back plate.
Secure the thermostat by tightening the screw provided to protect the thermostat from unwanted access.
The following instructions provide information to test the heating / cooling equipment and to change operating parameters from the factory settings.
Enter Installer Setup
Testing Heating / Cooling Equipment. (OP:01)
While in the installer setup, slide the mode switch to heat to operate the heating equipment or cool to operate the cooling equipment. The display will show either 00 or 01 on the lower right area and either heat or cool as selected by the mode switch.
Setting °C / °F Indication. (OP:02)
While in the installer setup,
NOTE: Factory setting is °F indication.
Setting Heating Cycle Rate. (OP:03)
In cooling, the cycle rate is fixed at 3 Cycles per hour. To set the cycle rate in heating; while in installer setup,
Setting cooling algorithm. (OP:04)
The cooling algorithm can be selected as normal or aggressive. For aggressive, the system will cool down the room to setting point faster than normal algorithm. However, an overshoot might occurred in some situations.

Minimum Off Timer
For cooling, when the thermostat calls for operation while the minimum off timer is not expired, the star symbol keeps flashing
Back Lighting ( TE86SB )
The thermostat features a back light that will illuminate all the time. The user can easily see the LCD screen under dim light situation

Application Note
Attached 1000 ohm, 3 watt resistor is used in certain applications to assure compatibility with power stealing thermostats where Fan does not come ON during call for Heat or Cool. Note that resistor has to be installed at the fan terminals and not at thermostat terminals.
