Excel T7515A-D M-Cel® Space Temperature Sensors. CSI 3-Part Specifications.

Excel T7515A-D M-Cel� Space Temperature Sensors

GENERAL

The Excel T7515A-D M-Cel Space Temperature Sensors ("Space Sensors") are platinum Resistance Temperature Devices (RTDs) used with Excel MicroCel™ and MacroCel™ Controllers to control Variable Air Volume (VAV) terminal units, water-source heat pumps, air handling units, and other equipment. Space Sensors are available with or without an integral setpoint adjustment dial and an occupant override push button with status LED. The push button allows setting the heating or cooling system to normal when the control system is in the unoccupied mode. The LED indicates the override status. These Space Sensors are furnished with a connector for local operation of a Excel CCT2190 M-Cel Portable Operator Terminal.

FEATURES

• Platinum sensor

• Full setpoint adjustment option

• Override push button/LED option

• Fahrenheit or Centigrade scales
