Do not use on circuits exceeding specified voltage.

Higher voltage will damage control and could cause

shock or fire hazard.

Do not short out terminals on gas valve or primary

control to test. Short or incorrect wiring will damage

thermostat and could cause personal injury and/or

property damage.

Thermostat installation and all components of the

system shall conform to Class II (current limited)

circuits per the NEC code. Failure to do so could cause

a fire hazard.

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

PRECAUTIONS

This thermostat is intended for use with a low voltage NEC Class

II system. Do not use this thermostat with a line voltage system.

If in doubt about whether your wiring is millivolt, line, or low

voltage, have it inspected by a qualified heating and air condi-

tioning contractor or electrician.

Do not exceed the specification ratings.

All wiring must conform to local and national electrical codes

and ordinances.

This control is a precision instrument, and should be handled

carefully. Rough handling or distorting components could cause

the control to malfunction.

To prevent electrical shock and/or equipment dam-

age, disconnect electric power to system at main fuse

or circuit breaker box until installation is complete.

Your new 5-Day/1-Day/1-Day Digital Thermostat uses the tech-

nology of a solid-state microcomputer to provide precise time/

temperature control. This thermostat offers you the flexibility to

design heating and cooling programs that fit your needs.

Features:

• Separate 5-day (weekday) and 1-day/1-day (Saturday/Sunday)

programming with four separate time/temperature periods per day

• Simultaneous heat and cool program storage

• Preprogrammed temperature control

• Optional battery back-up for AC power loss

F82-261 Programmable Electronic Digital Heat Pump Thermostat INSTALLATION AND OPERATION INSTRUCTIONS 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. DESCRIPTION Your new 5-Day/1-Day/1-Day Digital Thermostat uses the technology of a solid-state microcomputer to provide precise time/ temperature control.

INSTALLATION REMOVE OLD THERMOSTAT Optional (2) "AA" batteries 1. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. 2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. 3.

CHECK THERMOSTAT OPERATION Emergency System If at any time during testing your system does not operate properly, contact a qualified service person. EMER bypasses the Heat Pump to use the heat source wired to terminal E on the thermostat. EMER is typically used when compressor operation is not desired, or you prefer back-up heat only. 1. Move SYSTEM switch to EMER position, EMER will flash on the display. Turn on power to the system.

The Display Press HOLD to change to the next menu item or press TIME to go backwards to the previous item in the menu. To exit the menu and return to the program operation, press RUN. If no keys are pressed within fifteen minutes, the thermostat will revert to normal operation. 9 Indicates day of the week. 10 Indicates a malfunction with the system. 1) Select Temporary Hold Time - The thermostat can hold any temperature you set it to for the amount of time you select on this option.

4) Select backlit display - The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on continuously. Selecting OFF will keep the light off. 5) Select Energy Management Recovery OFF or ON Energy Management Recovery (EMR) causes the thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify.

Use the table to plan your program time periods and the temperatures you want during each period. Fill in the complete table to have a record of your programs. 6. Repeat steps 3 and 4 to select the start time and heating temperature for the 2nd heating program period. 7. Repeat steps 3 through 5 for the 3rd and 4th heating program periods. 8. Press PRGM once.

TROUBLESHOOTING Reset Operation If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, reset the thermostat by pressing the reset switch (see Fig 1). If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase. Symptom Possible Cause Corrective Action No Hea t/No Cool/No F an Heat/No Fan (common problems) 1. Blown fuse or tripped circuit breaker. 2.
