GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

ROOM TEMPERATURE SENSOR

TSPC SERIES

PRODUCT DESCRIPTION

The TSPC room temperature sensor with resistive

setpoint control is available in an attractive wall

mount enclosure and can be configured with various

options. It is available with various curve-matched

thermistors or RTD sensors to measure temperature.

A back-lit LCD displays room temperature, setpoint

on demand and occupancy. Several operating

parameters can be programmed using a keypad

and on-board jumpers configure the ˚C/°F display or

disable the backlight.

Available options include a dry-contact override

switch, a five position fan speed switch and a jack for

a network connection.

TYPICAL INSTALLATION

For complete installation and wiring details,

please refer to the product installation

instructions.

The TSPC series can be mounted directly to a single

gang electrical box or directly to a wall. Insulating

foam is adhered to the back of the enclosure

to provide a thermal barrier from internal wall

temperatures.

A terminal block connection is provided for

connection to the Building Automation System. There

are several wiring configurations depending on the

options selected.
