More control for more savings
Cut energy costs, and achieve higher levels of comfort—
automatically with Simplicity
More intelligence for more capabilities
Intelli-Comfort controls use intelligent hardware and
software to give you better monitoring, more flexibility in
control set-up, and finer control of every aspect of your
HVAC system. In addition, the more intelligent the control,
the greater savings you will realize through operational
efficiencies and conservation.
More control for greater comfort
-
The flexibility of the Simplicity Intelli-Comfort control
UP
means comfortable, happier, and more productive
occupants—thanks to the ability to optimize temperature,
humidity, and indoor air quality simultaneously.
Put the intelligence of Simplicity Intelli-Comfort controls
to work in your building.
Simplicity Intelli-Comfort controls give you powerful capabilities without complexity. Easy to set-up, program, and use, the controls give you
everything you need to monitor and control Sunline and Predator units. And because they can be connected as your HVAC Energy
Management System you can save even more by making the intelligence of Simplicity Intelli-Comfort part of your building automation strategy.
New features for superior
monitoring and control
365-Day Real Time Clock with
automatic Daylight Savings Time adjustment
Occupancy Schedule allowing two different occupied
schedules per day for each of the seven days of the week
20 Holiday Schedules with a length of up to 99 days, each
with flexible start times. You can now choose the time of day
your holiday begins saving energy
Energy-Saving Economizer Operation with the flexibility
of using dry bulb, outside enthalpy and differential enthalpy.
Our economizer enthalpy control has setpoints for outside air
temperature, supply air temperature, small space cooling demand,
and large space cooling demand
Outside Air CO
Inside Demand Ventilation using one CO
demand ventilation using inside and outside CO
IAQ Operation with programmable maximum outside air
damper position
Comfort Ventilation Control tempers the ventilation air
when heating or cooling is not required, increasing comfort

Controls

HVAC control just became a
whole lot smarter and easier!
More compatibility for more flexibility
The controls are compatible with the MODBUS protocol,
® Intelli-Comfort ™ controls. and are factory-installed on 3- to 25-ton Sunline
Predator
More power with less effort
Intelli-Comfort is a control that's so easy to use that
you actually benefit from the power at your fingertips.
Easier to manage
Intelli-Comfort raises the intelligence of an already
smart Simplicity control.
Patent Pending Temperature Humidity Algorithm offsets
the operating setpoint based on high humidity in the space—with
programmable limits to control humidity
High and Low Ambient Lockout to lockout cooling below or
heating above a programmable setpoint of outside air temperature
Space Temperature Alarm when temperatures are outside
of program setpoints. Alarm setpoints are user programmable
Unit Monitors Airflow to detect dirty filters and insufficient airflow
Sensor to close the economizer if CO is present
