Introduction

TC500A-N/TC500A-W Commercial Touchscreen 

Thermostat is designed to be wall-mounted indoors. 

Mount in a clean, dry location away from windows, air 

ducts, and other places where environmental factors may 

affect temperature and humidity readings. If you mount 

the Thermostat unit on the interior of an outside wall, 

thoroughly insulate so outside air behind the sensor does 

not affect the sensor reading. 

To meet requirements of the Americans with Disabilities 

Act, mount no higher than 48" from the floor and with a 

minimum clear floor space of 30" X 48" (760 X 1220 mm).

Location

Do not install the Thermostat unit where it can be affected 

by:

— drafts or dead spots behind doors and in corners.

— hot or cold air from ducts.

— radiant heat from sun or appliances.

— concealed pipes and chimneys.

— unheated (uncooled) areas such as an outside wall

-

behind the thermostat.

IMPORTANT

To avoid electrical interference, which can cause 

erratic performances, keep wiring runs as short as 

possible and do not run thermostat wires adjacent 

to the line voltage electrical distribution systems. 

Use shielded cable. The cable shield must be 

grounded only at the controlled equipment case.

WHEN USED TO SENSE ROOM TEMPERATURE

Install the Thermostat about 4 ft. (1.2m) above the floor in 

an area with good air circulation at average temperature. 

(See Fig. 1). Confirm mounting height meets Americans 

with Disabilities Act requirements.

WHEN NOT USED TO SENSE ROOM TEMPERATURE

When using the remote-mounted temperature (and 

humidity) sensor(s) to sense ambient conditions, install 

the Thermostat in an area that is accessible for setting and 

adjusting the temperature and settings.
