Thermostats are specifically designed for single-stage
and multi-stage control of heating/cooling equipment,
such as rooftop and heat pump units.
Code No. LIT-1201911
www.johnsoncontrols.com
Software Release 1.0
Accurate temperature control is achieved with a time
proportional control algorithm, which virtually
eliminates the temperature offset associated with
traditional, differential-based thermostats. For more
advanced applications, an economizer control logic
has been integrated onto the thermostat for use with
proportional damper economizer actuators.
All programmable models contain a Single-Pole
Single-Throw (SPST) auxiliary switch, which can be
used to control lighting or disable the economizer
function.
