Preci sion Zone Cont rol
The T168 microprocessor thermostat is a stand-alone digital controller that
supplies 0-10 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.
Easy- to-Use Di splay
The digital display, with easy-to-use adjustment buttons, allows convenient
access to current zone temperature, setpoint temperature and operating
mode.
Optimal Flexibility
This flexible control offers auto changeover, setback and staged/auxiliary heat
for adapting to application requirements.
