T600xxx-3 Series Thermostats

Product Bulletin

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 p rovide exceptional
temperature control in an easy-to-use, yet flexible,
package. The T600xxx-3 Series thermostat s have over
20 configurable parameters, enabling the thermo stats
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
thermostats.

T600xxx-3 Series Thermostats Product Bulletin 1

Product Overview

The T600xxx-3 Series thermostats are sp ecifically
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 T600xxP-3 Series programmable thermostats
feature a fully programmable 7-day, 2- or 4-event
schedule, along with two programmable digital inputs
and one configurable output, enabling effective and
efficient control of equipment in nearly any application.

IMPORTANT: Use the T600xxx-3 thermostat only
as an operating control. Where failure or malfunction
of these thermostats could le ad to p er sonal injury o r
property damage to the controlled equipment or
other property, additional precautions must be
designed into the system. Incorporate and maintain
other devices such as supervisory or alarm systems
or safety or limit controls intended to warn of, or
protect against, failure or malfunction of the
thermostats.

Additional Features

The T600xxx-3 Series thermostats also offer many
other features:

• Adjustable Heating/Cooling Deadband
Adjusts the minimum heating/cooling deadband
from 2 to 4F° (1 to 2C°).

• 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
averaged.

• Three Levels of Keypad Lockout
Provide three different levels of keypad lockout that
can be set up through the menu and interface
keys.

• 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
thermostat’s mode.

• Adjustable Temporary Occupancy Time
Adjusts the occupancy override time from
0to12hours.

• High and Low Balance Point Adjustments
Enable more precise control of heat pump
operation based on outdoor air temperature
(T600HPx-3).

• 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.

• Adjustable Maximum Heating/Minimum Cooling

Setpoints

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
cycling.

• Smart Fan
Enables the fan to operate continuously during the
occupied times and cycle with the equipment
during the unoccupied times.

• Non-volatile EEPROM Memory
Prevents loss of adjusted parame ters during power
failure.

• Power Loss Backup for Clock (T600xxP-3)
Retains clock setting for up to 6 hours in case of
power loss.

• Heating and Cooling Stage Enable/Disable
(T600MEP-3, T600MSx-3)
Allows operation of the second-stage heating and
cooling to be disabled, reverting the thermostat to
single-stage operation on multi-stage the rmostats.

• Heat Pump Compressor Stage Enable/Disable

(T600HPx-3)

Allows operation of the second-stage compressor
to be disabled, reverting the thermostat to single­stage compressor operation on heat pump
thermostats.
