Floating and Proportional Thermostats T158, T168 Series

Floating and Proportional Thermostats

 

The PECO T158 Series is a microprocessor based floating or two-position low voltage thermostat. The T168 Series is a microprocessor-based proportional 4-20 mA or 0-10V thermostat. Both series are designed for fan coil and air handler applications for both two- and four-pipe systems. The processor provides control algorithms for precise stable control under varying capacity and load conditions without the need for field calibration or tuning. These versatile thermostats have options for a variety of high voltage fan and system switching. Models are also available with an unoccupied setback input. Terminations are provided for remote sensors for both air and water temperature.
