The SRT-DSPLCD is an adjustable set point room sensor complete with LCD temperature display. It is intended for use with Hevac brand HTC 3, 5 and Digital series controllers. The sensor has a NTC characteristic (increase in temperature = decrease in resistance) and changes approximately 80 ohms per degree. Both a concealed and exposed adjustment knob are included, allowing plus or minus 3.5°C from the HTC’s main setpoint.
