Digital Controller for Accurate Zone Comfort
The T158 microprocessor-controlled thermostat is a stand-alone digital
controller that supplies 24 VAC output control for valves, dampers, relays and
three-wire floating valves. The use of an advanced proportional integral (PI)
algorithm allows precise control of zone comfort under varying operational and
environmental conditions.
Easy-to-Use Digital Display
The digital display, with easy-to-use adjustment buttons, allows convenient
access to current zone temperature, setpoint temperature and operating
mode.
Adjustable for Application Requirements
Optional pipe sensor changeover, setback and staged heat functions are
available, on selected models, for adapting to application requirements.
