THERMOSTAT LOCATION
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-LH121 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
●
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.
