T600HPP-2 Programmable Thermostat

Application

IMPORTANT: Use this T600HPP-2

programmable thermostat only as an operating
control. Where failure or malfunction of the
thermostat could lead to personal injury or 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 thermostat.

The T600HPP-2 is a programmable heat pump
thermostat that provides exceptional accuracy through
the use of a unique Proportional-Integral (PI) time
proportioning algorithm. The algorithm virtually
eliminates temperature offset associated with
traditional, differential-based on/off thermostats. The
T600HPP-2 also uses an adaptive control logic
algorithm to control the space temperature during
recovery to minimize overshoot while providing
maximum comfort. Additionally, the menu driven
backlit display, plain text menus, and five keys on the
T600HPP-2 make programming the thermostat easy
and intuitive.

To install the thermostat:

1. Remove the security screw on the bottom of the
thermostat cover using a Phillips-head
screwdriver. Open the thermostat by pulling on the
bottom side of the thermostat cover (Figure 1).

2. Unlock the Printed Circuit Board (PCB) by
carefully pressing the locking tab to the right
(Figure 2). Open the thermostat’s PCB to the left.

3. Pull out approximately 6 in. (152 mm) of wires
from the wall and insert the cable through the hole
in the base.

4. Align the base on the wall, and using the base as
a template, mark the location of the two mounting
holes on the wall. Confirm the thermostat base is
installed with the proper side up.

5. Use the supplied anchors and screws for mounting
on drywall or plaster. Drill two 3/16 in. (4.7 mm)
holes at the marked locations and tap nylon
anchors flush to wall surface (Figure 3).

6. Position base on the wall, insert screws through
mounting base, and fasten into wall anchors. Do
not overtighten screws.

Installation

7. Swing the thermostat PCB back to the right to
close. Gently press on the PCB to secure each of

Location Considerations

Locate the T600HPP-2 thermostat:

• on a partitioning interior wall, and approximately
5 ft. (1.5 m) above the floor in a location of
average temperature

the locking tabs.

8. Pull out the screw terminal blocks using the
pull-tabs on each connector (Figure 4).

Note: The number of terminals on the terminal
blocks varies depending on the T600 model.

• away from direct sunlight, radiant heat, outside
walls, behind doors, air discharge grills, stairwells,
or outside doors

• away from steam or water pipes, warm air stacks,
unheated/uncooled areas, or sources of electrical
interference

!

CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.

Note: When replacing an existing thermostat,
remove and label wires to identify terminal
designations. When replacing a T600HPP thermostat,
simply remove the terminal blocks and reinsert on to
the new thermostat.

To wire the thermostat:

1. Strip each wire 1/4 in. (6.35 mm) and connect to
the appropriate terminal according to the wiring
diagram (Figure 5).

2. Gently push excess wire back into wall, plug the
wall hole with fireproof material to prevent drafts
from affecting ambient temperature readings, and
install screw terminal blocks back onto the PCB.

3. Reattach the thermostat cover to the installed
base (top side first) and install the security screw
on the bottom.

!

CAUTION: Risk of Property Damage.

Do not apply power to the system before checking
all wiring connections. Short circuited or improperly
connected wires may result in permanent damage to
the equipment.

Backlit Liquid Crystal Display (LCD)

The T600HPP-2 uses a two-line, eight-character
backlit display. Low level backlighting is present during
normal operation and it brightens when any user
interface key is pressed. The backlight returns to the
lower level when the thermostat is left unattended for
45 seconds.

Light-Emitting Diodes (LED)s

Three LEDs are used to indicate the status of the fan,
call for heat, or call for cooling. When:

• the fan is on, the FAN LED lights up

• auxiliary heat is on, the AUX HEAT LED lights up

Programming Overview

There are three menus used to view, program, and
configure the T600HPP-2 thermostat: the Status
Display, Main User, and Installer Configuration Menus.

The Status Display Menu is displayed during normal
thermostat operation. The menu continually scrolls
through the following parameters.

• Room Temperature

• Day and Time

• System Mode

• Schedule Status (Occupied/Unoccupied)

• Outdoor Temperature (providing sensor is

connected and functional)

• Applicable Alarms (the backlight lights up as an
alarm condition is displayed)

To temporarily stop the scrolling, press the
YES/SCROLL key.

The Main User Menu is used to access and change
the thermostat’s basic operating parameters. Access
the menu by pressing the MENU key during normal
thermostat operation.

The Installer Configuration Menu is used to set up
the thermostat for application specific operation.
Access the menu by removing the front cover and
pressing the configuration key, labeled CONFIG
(Figure 7).

Configuring the T600HPP-2

The T600HPP-2 ships from the factory with default
settings for all configurable parameters. The default
settings are shown in Table 1. To reconfigure the
parameters, follow the steps in this section for the
corresponding parameters. To set up the parameters,
access the Installer Configuration Menu. Access the
Installer Configuration Menu by removing the front
cover and pressing the configuration key (Figure 7).

Exit the Installer Configuration Menu any time by
pressing the MENU key and, at the exit prompt,
pressing the YES key. To pass over a parameter
without changing it, press the NO key.

When the thermostat is in the Installer Configuration
Menu and left unattended for 45 seconds, it reverts to
the Status Display Menu.
