TA168 PROPORTIONAL THERMOSTAT –
0 – 10 VDC / 4 – 20 MA
The TA168 microprocessor thermostat is a stand-alone digital controller that supplies
0 - 10V VDC or 4 - 20 mA output control of valves and dampers. The use of an advanced proportional integral
(PI) algorithm allows precise control of zone comfort under varying operational and environmental conditions.
The digital display, with easy-to-use adjustment buttons, allows convenient access to current zone
temperature, set point temperature and operating mode. Optional changeover, setback and auxiliary heat
functions are available, on selected models, for adapting to application requirements.
