Description: 3HT/2CL Heat Pump Non Prog TSTAT
T600xxx-3 Series Thermostats
The T600xxN-3 Series non-programmable and
T600xxP-3 Series programmable thermostats are
specifically designed for control of single-stage, multistage,
and heat pump commercial heating and cooling
equipment. The T600xxP-3 Series thermostats are
also specifically designed for control of rooftop units
(with and without economizers).
The T600xxx-3 Series thermostats provide exceptional
temperature control in an easy-to-use, yet flexible,
package. The T600xxx-3 Series thermostats have over
20 configurable parameters, enabling the thermostats
to adapt to a variety of applications.
The T600xxx-3 Series thermostats include several
models: Single-stage (T600HCx-3), Heat Pump
(T600HPx-3), Multi-stage (T600MSx-3), and
Economizer (T600MEP-3). All thermostats use a
unique Proportional-Integral (PI) proportional control
algorithm that virtually eliminates temperature offset
associated with traditional differential based
The T600xxx-3 Series thermostats are specifically
designed for control of the most common commercial
heating and cooling equipment. A number of
configurable parameters enable the
T600xxx-3 Series thermostat to effectively and
efficiently control various types of equipment in nearly
any application. Configuration, setup, and operation of
the T600xxx-3 Series thermostat are extremely intuitive
and are accomplished through the user interface.
The T600xxx-3 Series thermostats also offer many
• Adjustable Heating/Cooling Deadband
Adjusts the minimum heating/cooling deadband
from 2 to 4F° (1 to 2C°).
• Adjustable Maximum Heating/Minimum Cooling
Establish the maximum heating setpoint and
minimum cooling setpoint that can be entered
through the user interface.
• Progressive Recovery
Ensures the correct temperature is reached at the
programmed occupied time.
• Adjustable Heating/Cooling Cycles per Hour
Configurable for a maximum of 3 to 8 heating
cycles and 3 or 4 cooling cycles in a 1-hour period,
balancing temperature control and equipment
• Smart Fan
Enables the fan to operate continuously during the
occupied times and cycle with the equipment
during the unoccupied times.
• Adjustable Power Delay on Start-up
Enables a delay before any operation is authorized
upon power up of the thermostat. Can be used for
equipment protection or to sequence start-up of
multiple units in one location.
• Remote Indoor and Outdoor Sensing
Accommodates remote indoor and outdoor
sensors. Up to three indoor sensors can be
• Three Levels of Keypad Lockout
Provide three different levels of keypad lockout that
can be set up through the menu and interface
• Adjustable Anti-Short Cycling Timer
Adjusts the minimum on and off times for the
equipment from 0 to 5 minutes.
• Frost Protection Enable/Disable
Turns the heat on when the zone temperature
drops below 42°F (5.5°C) regardless of the
• Adjustable Temporary Occupancy Time
Adjusts the occupancy override time from
0 to 12 hours.
• System Mode Lockout
Allows the heating and cooling modes to be locked
out based on outdoor air temperature when an
outdoor air sensor is connected.
• Non-volatile EEPROM Memory
Prevents loss of adjusted parameters during power
• Power Loss Backup for Clock (T600xxP-3)
Retains clock setting for up to 6 hours in case of
• Heating and Cooling Stage Enable/Disable
Allows operation of the second-stage heating and
cooling to be disabled, reverting the thermostat to
single-stage operation on multi-stage thermostats.
