Please read all instructions carefully before beginning 

installation and save for future reference.  Before 

removing any wiring from your existing thermostat, its 

wires must be labeled with their terminal designations.  

Ignore the color of the wires since they may not 

comply with any standard.

Thank you for your confidence in our product. To obtain the best results 

from your investment, please read this manual and acquaint yourself with 

your purchase before installing your new thermostat. Then follow the 

installation procedures, one step at a time. This will save you time and 

minimize the chance of damaging the thermostat and the systems it 

controls. These instructions may contain information beyond that required 

for your particular installation. Please save for future reference.

INSTALLATION

Please read all instructions carefully before beginning installation.

C A U T I O N

Turn off electricity to the appliance before installing or

 

servicing thermostat or any part of the system. Do not turn

 

electricity back on until work is completed.

Do not short (jumper) across electric terminals at control on furnace or 

air conditioner to test the system. This will damage the thermostat and 

void your warranty.

All wiring must conform to local codes and ordinances.

This thermostat is designed for use with 24 volt and millivolt systems.

The thermostat should be limited to a maximum of 1.5 amps; higher

current may cause damage to the thermostat. If you are in doubt, call 

your HVAC contractor.

Your thermostat is a precision instrument. Please handle it with care.

TOOLS REQUIRED

MODE

 

On replacement installations, mount the new thermostat in place of the 

old one unless the conditions listed below suggest otherwise. On new 

installations, follow the guidelines listed below.

Remember that your 

TP-L111

 may be mounted vertically or

horizontally

 

when determining the optimal location.

Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the

floor, and in a room that is used often.

Do not install it where there are unusual heating conditions, such as: in

direct sunlight; near a lamp, radio, television, radiator, register, or 

fireplace; near hot water pipes in a wall; near

 

a stove on the other side

of a wall

.

Do not locate in unusual cooling conditions, such as: on a wall

separating an unheated room; or in a draft from a stairwell, door, or

window.

Do not locate in a damp area. This can lead to corrosion that will

shorten thermostat life.

Do not locate where air circulation is poor, such as: in a corner or an

alcove; or behind an open door.

Do not install the unit until all construction work and painting has been 

completed.
