SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow all local electrical codes during
installation. All wiring must conform to local and national electrical codes. Improper wiring or
installation may damage the Thermostat.
Recognize safety information. This is the safety--alert symbol When you see this symbol
on the equipment and in the instruction manual, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAUTION. These words are used
with the safety--alert symbol. DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies a hazard which could result in personal
injury or death. CAUTION is used to identify unsafe practices which may result in minor
personal injury or product and property damage. NOTE is used to highlight suggestions which
will result in enhanced installation, reliability, or operation.
INTRODUCTION
The Côr 5 series and Côr 7 series thermostat models are 7-day, 5/2-day, 1-day programmable
control is a wall-mounted, low-voltage controls. The Côr 7 and Côr 7C combines temperature
and humidity control in the units. The Côr Thermostats have no need for batteries to store user-
configured settings in memory. During power loss its internal memory saves settings for
unlimited time, and the clock continues to run for at least 24 hours.
A Two-Wire Relay Module option for the Côr 7 series thermostats allows them to connect to a
system using only two thermostat wires at the wall. The Two-Wire Relay Module is located near
the equipment and two wires are used between the thermostat and the Two-Wire Relay Module.

In the Côr thermostat programmable configuration, different heating and cooling setpoints and
times are programmable for 4 periods per day or 2 periods per day. Programming can be done for
7 days per week, 5/2 days per week, or 1 day. The programmable thermostat can also be user
configured as a non-programmable thermostat. When operating as non-programmable, the Côr
Thermostat will still have temperature control and in the Côr 7 series, humidity control. The Côr
7 series Thermostat features Touch-N-Go® settings for quick and easy temperature change
without complicated programming schedules.
INSTALLATION CONSIDERATIONS
Power
This Thermostat is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals)
of the low-voltage transformer to be connected to it for proper operation. It will not operate
without these 2 connections. Rh and Rc are connected via PCB breakout jumper. See Fig. 1. For
applications using two 24VAC transformers, one in the indoor unit and one in the outdoor unit,
connect the common from each to the C terminal. Connect R from the indoor unit to the Rh
terminal. Connect R from the outdoor unit to the Rc terminal. Then, break jumper on the circuit
board (fig. 1). The W and HUM signals are taken from the Rh power and the G signal is taken
from the Rc power. If Thermostat has been installed in a two--transformer application that is
later changed to a single--transformer installation, installer must install a field supplied jumper
between Rc and Rh. Depending on the installation, up to 14 wires may be required. Installation
with the Two-Wire Relay Module is recommended. Only 2 wires are required for connection
between the thermostat on the wall and the Two-Wire Relay Module. These two wires (V+ and
Vg) do not provide ordinary 24VAC. They carry a combination of power and communications
data that is unique to these products.

Models
The Côr 5 and Côr 5C models are temperature control only and the Côr 7 and Côr 7C are
temperature and humidity control. All 4 can be configured for AC or HP, 1 or 2-speed
4
compressor, and for Hybrid Heat installations. These thermostats may be configured as non-
programmable if user desires.
Humidify Equipment and Connections
The humidify output connects directly to 24VAC operated humidifiers. An isolation relay may
be required when using powered humidifiers. No other connection or interlock is required. Any
of several installer-selectable operating modes are available.
Why delete the warning?
Dehumidify Equipment and Connections
On the two-wire relay option see (Insert the Title of those instructions here). The dry contact
output connects to the dehumidify input on variable—speed furnaces and fan coils. Additional
dehumidification is done by controlling the compressor. A variety of operating modes are
available. The dry contact must be configured for dehumidification in setup SW19. See Wiring
Diagrams for more information.
Outdoor Temperature Sensor (TSTATCCSEN01--B)
Outdoor air temperature sensor is a separate accessory for units installed with the Two-Wire
Relay Module. Optimum performance is obtained when an outdoor temperature sensor is used
with the Côr 7 series thermostat. Plan installation so that 2 wires can be run from the Two-Wire
Relay Module to an outdoor location, preferably on the north side of the house or refer to
Installation Instructions included with the outdoor temperature sensor for simplified connection.
The sensor can be mounted to the outdoor unit and existing control wires may be used for its
connection. Details are provided in sensor instructions.
Remote Indoor Temperature Sensor
A remote temperature sensor may be used with the Two-Wire Relay Module, where it is
desirable to install the Côr 7 series thermostat in a limited access location while measuring the
temperature in the living space. The remote room sensor may be used as a standalone or
averaged with the thermostats local sensor.

Wiring
For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths over 100 ft.
(30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed 250 ft. (76 m) per run.
INSTALLATION
Installation Notes:
No part of the Thermostat should be installed directly outdoors or in a cabinet outdoors.
Never remove the thermostat board from the plastic housing. Doing so could warp and
damage the components on the board.
The mounting plate should be mounted to the wall before wires are attached.
During thermostat installation, provide sufficient excess wiring behind the mounting
plate. Coil the wiring, creating a service loop, and place in mounting box or behind the
wall to remove strain against the terminal strip. See Fig. 2.

Thermostat Location
The thermostat should be mounted:
Approximately 5 ft. (1.5m) from floor.
Close to or in a frequently used room, preferably on an inside partitioning wall.
On a section of wall without pipes or duct work.
The thermostat should NOT be mounted:
Close to a window, on an outside wall, or next to a door leading to the outside.
Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature-radiating
objects which could cause a false reading.
Close to or in direct airflow from supply registers and return-air registers.
In areas with poor air circulation, such as behind a door or in an alcove.
Install Thermostat

1. Turn off all power to equipment.
2. If an existing thermostat is being replaced:
a. Remove existing Thermostat from wall.
b. Disconnect wires from existing thermostat, 1 at a time.
c. As each wire is disconnected, record wire color and terminal marking.
d. New or additional wires may be needed to accommodate C wire or added humidity
output on Côr 7 series.
e. Discard or recycle old Thermostat.

Fig. 3 –Release Tabs to Remove Backplate
1. Use a small screwdriver to release tabs when removing the backplate (Fig. 3).
2. Route wires through large hole in mounting base. Level mounting base against wall
(for aesthetic value only—Thermostat need not be leveled for proper operation) and
mark wall through mounting holes. With the additional mounting holes you might be
able to reuse existing mounting locations.

3. Drill 3/16--in. mounting holes in wall where marked. Thermostat may be mounted to a
standard junction box, if desired. Hole pattern on the Thermostat mounting base matches
junction box mounting holes.
4. Secure plastic mounting base to wall with screws and anchors provided. Use 2 screws
and 2 anchors provided for a secure attachment. Make sure all wires extend through hole
in mounting base.
5. Adjust length and routing of each wire to reach proper connector block and terminal on
mounting base with 1/4--in. (6 mm) extra wire.
6. Match and connect equipment wires to proper terminals of each connector block, being
careful not to over tighten the screws.

7. Push any excess wire into wall and against mounting base. Seal hole in wall to prevent air
leaks. Leaks can affect operation and cause incorrect temperature and/or humidity
measurement.
8. Reattach thermostat front to mounting base by first setting on at top of mounting base and
then push bottom corners of Display Module to snap into place. See Fig. 11.
