GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

DESCRIPTION:

The TSPC room temperature sensor with resistive setpoint control is available in an attractive wall mount
enclosure and can be congured 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 congure the ˚C/F display or disable the backlight.

Available options include a dry-contact override switch, a ve position fan speed switch and a jack for a
network connection.
