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 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,andCAUTION. 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 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 12 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 indoor equipment and two wires are used between the thermostat and the Two--Wire
Relay Module.

INSTALLATIONS WITHOUT A COMMON (C) WIRE
If your current thermostat does not have a wire connected to the C, the following options are available:
1. Repurpose the G wire as a C wire per the instructions below.
2. Use the Add--A--Wire for the Côr 5/5C or Use the Two Wire Relay Module for the Côr 7/7C thermostats.
3. Run an additional wire from the equipment to the thermostat.
Repurposing the G wire for the C wire – Single Stage Equipment
NOTE: Repurposing G wire for the C wire will result in the loss of continuous fan operation and air circulation feature of the thermostat.

11
IMPORTANT: This is only recommended on single stage Gas, Oil or Propane Furnace equipment applications with 4 wires running the
thermostat (R, W, Y, G) and Carrier/Bryant Fan Coils.
1. Use the G wire for the C wire at the equipment.
2. Add a jumper wire from Y (or Y1) to G on the furnace board or Fancoil wiring to allow the blower to turn on during cooling opera-
tion.
3. Connect repurposed wire to the Thermostat.
4. Follow standard installation instructions to complete installation.
NOTE: There will no longer be a wire connected to the G terminal at the thermostat.

5to55_F (--15 to 13_C) — the outdoor temperature below which heat pump operation is not allowed.
This selection determines which sensor the Thermostat will use for measuring room air temperature. Room air temperature can be sensed in
one of three ways; the local sensor (L) located on the Display Module, the remote room air sensor (r), or the average of local and remote
sensors (Lr). Settings are L, r, Lr.
Default is L.
SW10 —Reversing Valve
This selection is only available on heat pump systems. “O” terminal can be configured to be energized in either heating mode or in cooling
mode, depending on heat pump operation. “O” is used to describe a heat pump system that energizes its reversing valve in cooling. “B” is
used to describe a heat pump system that energized its reversing valve in heating.
H — Reversing valve output (O/W2/B) is energized when HEAT mode is selected.
C — Reversing valve output (O/W2/B) is energized when COOL mode is selected.
Default is C.
SW11 —Deadband Setting Between Heat & Cool
This option is NOT available on Heat Only and Cool Only systems. The selection allows the installer to choose how much differential exists
between the heating and cooling setpoints. Allowable selections are 1 thru 6.
Default is 2.
SW12 —Smart Recovery
Smart Recovery OFF means setpoints change precisely at setback recovery time. 30, 60, or 90 selects the number of minutes recovery starts
before programmed recovery time. Recovery takes place smoothly during the selected recovery time, ending at the recovery time and
temperature which is programmed. Not available when thermostat is configured as non--programmable.
Default is 60.
SW13 —Room Air Temperature Offset Adjust
The number of degrees to be added to the displayed temperature to calibrate or deliberately miscalibrate the measured room temperature (--5

This selection is not available if the Thermostat is configured as Heat Only or Cool Only in SW1. This allows the homeowner to select auto
changeover mode in addition to heat and cool. This allows the Thermostat to automatically change between heating mode and cooling mode
when sufficient demand for heating or cooling exists.
ON — Auto mode is available.
OFF — Auto mode is not available.
Default is ON

16
SW16 —Maximum Cycles Per Hour
This selection limits the number of cycles per hour that the Thermostat allows the system to operate. Selections are 2, 4, 6.
2 — The heating and cooling outputs will be energized no more than 2 times per hour. When an output is energized, it will not be energized
again for 30 minutes.
4 — The heating and cooling outputs will be energized no more than 4 times per hour. When an output is energized, it will not be energized
again for 15 minutes.
6 — The heating and cooling outputs will be energized no more than 6 times per hour. When an output is energized, it will not be energized
again for 10 minutes.
Default is 4.
SW17 —Minimum Time Between Equipment Stages
This selection is only available for heat pump systems. This determines the minimum number of minutes of equipment operation on the
highest compressor stage before allowing the transition to auxiliary heat. Available selections are 10, 15, 20, and 25. The minimum time
between stages of any individual piece of equipment, such as low speed and high speed compressor or fan coil stages, will be fixed at 10
minutes.

this selection is changed from OFF to VENT, Ventilation will be available in the homeowners menu under schedule (from the home screen
tap menu, select when schedule is blinking then the up/dn arrow to ventilation). Wake will be shown above the min/hr. the up/dn arrow will
adjust min/hr between 0 and 60. Press Next to move through the four periods and set the times per period. See Operational Information and
Wiring Diagrams for further explanation of dry contact configuration and use in the Two--Wire Relay Module installation instructions.
DEHUM — The dry contact will operate as a DH relay. This relay is reverse logic. When the humidity level is above the dehumidify setpoint,
the dry contact D1--D2 will be opened. When the humidity level is below the dehumidify setpoint, D1--D2 will be closed. There is a +/-- 2%
hysteresis around the dehumidify setpoint to prevent rapid on/off cycling of the DH output. When configured for dehumidification, the Rc
terminal must be connected to one of the dry contact terminals. This provides power to energize the dehumidify terminal on the cooling
equipment when the dry contact is closed. See Wiring Diagrams for more information.
Default is OFF.
SW20 —Outdoor Air Temperature Offset Adjustment
This selection allows the calibration, or deliberate miscalibration of the outdoor air temperature sensor reading. The selection ranges from --5
to +5_F.

SW22 —High Cool Latch Temperature
Only available if outdoor sensor is present or Wi--Fi weather is setup for the high cool latch feature.
This selection is only available when SW1 is set to H2, A2, or h2 and when SW7 (zoning) is set to OFF. Configuration settings are OFF, 80,
85, 90, 95, 100, 105, 110, On.
OFF — Cooling always starts in low stage (Y1) and stages up to high stage (Y1 and Y/Y2) when demand is sufficient and staging timer
constraints have been satisfied.
80 to 110_F (27 to 43_C) — Outdoor temperature above which both first and second stages of the compressor are energized to satisfy all
cooling demands. When a cycle starts under a high cool latch, it will finish the cooling cycle on high stage. If the cooling equipment is
energized to satisfy a dehumidify demand only (no cooling demand), the latch will not be applied.
ON — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all cooling demands.
Default is OFF.
SW23 —High Heat Latch Temperature (only available if outdoor sensor is present)

SW24 —Programmable/Non--Programmable
This selection allows the installer to configure the Thermostat as either programmable or non--programmable. Selections are P, nP.
Default is P.

17
SW25 —Number of Programmable Periods
This selection allows the installer to configure the Thermostat for two or four periods per day. Two periods is a common commercial
application and four periods is more common for residential. This selection is not available if SW24 has been set to nP to configure the
Thermostat for non—programmable operation.
2 PER — Periods WAKE and SLEEP are available
4 PER — Periods WAKE, AWAY, HOME, and SLEEP are available.
Default is 4.
SW26 —Minimum Cooling Setpoint
This selection allows the installer to configure the minimum cooling setpoint that the user is allowed to set. The range is based on the value of
the adjustable deadband SW11, such that the minimum of the range is 50_F/10_C plus the adjustable deadband and the maximum is
90_F/32_C.
Default is 52_F/11_C (based on the adjustable deadband default = 2).
SW27 —Maximum Heating Setpoint
This selection allows the installer to configure the maximum heating setpoint. The range is based on the adjustable deadband value SW11,
such that the minimum of the range is 50_F/10_C and the maximum is 90_F/32_C minus the deadband.
Default is 88_F/31_C (based on the adjustable deadband default = 2).
SW28 —UV Light Reminder
This selection allows the installer to select the number of months after which the UV Light reminder will be displayed to indicate to the
homeowner that it is time to call the dealer to have the UV Lights replaced. Selections available are OFF, 6, 12, 18, 24, 30, 36, 42, 48.
OFF — The UV Light reminder is turned off and will never be displayed.

OFF — The Humidifier Pad Reminder is disabled and will never be displayed.
1--24 — The number of months after which the Humidifier Pad Reminder icon will be displayed.
Default is OFF.
SW30 —Programmable Fan
This selection allows the homeowner to program the fan selection to “Auto” or “On” fan operation for each of the program schedule periods.
Also they can program air circulation by period.
OFF — Programmable fan is disabled and the homeowner must manually select “Auto” or “On” for fan operation and there is no option for
air circulation.
On — Programmable fan is enabled. The homeowner can program “Auto” or “On” fan operation along with the heat and cool setpoints for
each programmed period. When the program schedule is running, the programmed heat setpoint, cool setpoint, and fan selection for that
period will be used. If the homeowner “overrides” the programmed fan setting by pressing the fan button, the override selection will remain
in effect until the next programmed period time.
Default is ON.
SW32 —Furnace Heat Staging Control (available only when the Thermostat is configured to operate AC
or A2 equipment).
FURN – The Thermostat controls W1 output only and furnace controls the turn on and turn off of higher stages of heat.
TSTAT – The Thermostat will control the W1 and O/W2/B outputs.
Default is FURN.
SW34 — Hybrid Heat Furnace Latch
This selection allows a Hybrid Heat system to finish a heating cycle using the furnace.
On – Once the furnace is on, it will finish the heating cycle with the furnace. If a heat pump defrost occurs, the heating cycle will finish with
the furnace.
OFF – The system will stage from furnace back to heat pump if heating demand dictates, or 2 minutes after a defrost has ended.
Default is On.
SW35 – Advanced Smart Setback
This selection enables the Advanced Smart Setback algorithm.
On – When transitioning from the Away profile to the Home profile, the system will calculate the amount of time needed to efficiently reach
the desired home setpoint on--time.
OFF – When transitioning from the Away profile to the Home profile, the system will ramp according to the Smart recovery algorithm (30,
60, or 90 minute recovery).
Default is On.

18
SW40 —Humidify Fan
This selection controls whether humidification can only be done when a heating demand is present. If the homeowner turns humidification
OFF, this configuration operates as if the selection was set to OFF.
OFF – The humidity output will only energize when there is a humidity demand and the heating equipment is energized.
On – The humidity output and the fan will energize anytime humidification is needed during heating mode regardless of the state of the
heating equipment.
Factory default is OFF.
SW41 —Variable Speed Blower
This selection allows the installer to select between a single speed or variable motor. In a system with a two speed compressor (A2, h2, H2),
if a dehumidification demand exists and the compressor is energized for cool to dehumidify, cooling, or both, and the system has a PSC
blower (SW41 = OFF), then both Y/Y2 and Y1/W2 are energized.
OFF–Thesystemhasasinglespeed(PSC)blower.
On – The system has a variable speed blower.
Select OFF for geothermal applications.
Factory default is OFF.
SW42 —Variable Speed Super Dehumidification
This option will only be available if the Variable Speed Blower setup (SW41) has been set to ON.
OFF – The fan output (G) is energized when the compressor is on for cool to dehumidify functionality.
On – The fan output (G) is de--energized when the compressor is running for cool to dehumidify functionality. In this setup the fan will run at
very low speed because a Y/Y2 or Y1/W2 is present but the G signal is not. The fan output (G) will be energized any time the compressor is
energized in response to a cooling demand.
Factory default is OFF.
SW43 —Intelligent Heat Staging
This function is only available if the equipment configuration is a single speed heat pump (SW01 = HP).
OFF – Electric heat will not be staged.
On – Three stages of electric heat will be staged.
This switch should be set to On if the HVAC equipment has two banks of strip heaters. When electric heat is required, the thermostat will
energize the smallest bank first (W1 only), then the larger bank (turning the smaller bank off -- Y1/W2 only), and then both banks together
(both W1 and Y1/W2). When power is cycled to the thermostat, this unit configuration will be displayed as HS.
Factory defaults is OFF.
SW44 —Super Comfort Heat
This option is only available on heat pump units HP (HP, H2, hh1, and h2) when SW41 (Variable Speed Blower) is set to On and the system
has a valid outdoor air temperature sensor or Wi--Fi connection with weather setup
OFF – Comfort Heat is off.
On – Comfort Heat feature is on.
If the outdoor air temperature is between 12 to 40_F(--11to4_C) and the compressor is running in heating, then the fan output is turned off.
This will signal the variable speed blower to reduce the air speed. The fan output is turned off even if the user has the fan selection set to
continuous fan. The fan output will be turned back on in this temperature range if the maximum capacity of auxiliary heat is on due to system
demand (auxiliary heat on in response to a defrost signal shouldn’t cause the fan to turn back on).
If the outdoor air temperature is below 12_F/--11_C and there is sufficient demand for the equipment to be on, then the fan output is turned
back on and the W/W1 output is energized. In a two speed unit the Y/Y2 output should be energized in addition to the W/W1 output. This
logic does not apply to a Hybrid Heat system. In the unlikely event that the installer has selected a heat pump lockout temperature (SW09) of
5_F/--15_C in a Hybrid Heat system and the comfort heat feature is on, then the comfort heat feature will turn the W/W1 on and the
compressors off when the outdoor air temperature drops below 12_F/--11_C instead of at the lower temperature of 5_F/--15_C.
NOTE: All temperature boundaries have a +/-- 2_hysteresis.
Factory default is OFF.
SW99 —Reset to Factory Defaults
Use this capability to reset the Thermostat to “out of the box” conditions. BEWARE! All configuration settings, program settings, clock, and
calendar which have been manually entered will be lost! When this option is selected, the configuration number (SW99), will appear on the
left and 10 will appear on the right. To perform the reset, first use the NEXT key to move the box from the SW99 to the 10. Then press and
hold the DOWN key. The 10 will start counting down toward zero. If the DOWN key is kept pressed until the count reaches zero, the reset
will be performed. When the value reaches zero, the room air temperature shall display Fd and “RESETTING..” in the text box. When the
factory defaults have been restored, the Thermostat will act as if power was cycled and return to normal operation. If the DOWN key is
released early, the number will return to 10 and the reset will not occur.
NOTE: If you reset to factory defaults you will need to reconfigure the thermostat for the connected equipment. To reset homeowner
preferences exit the dealer setup menu and select menu from the home screen then select settings and go to item 14 “RST DEFAULT” to reset
user preferences.

SYSTEM START--UP AND TEST EQUIPMENT
The Thermostat is designed with a built--in installer test capability. It allows easy operation of equipment without delays or setpoint
adjustments to force heating or cooling. To enable installer Output Test mode, press and hold the fan button for 10 seconds. Pressing the
Heat/Cool button will change the system operating mode to test the heating and cooling equipment based on the equipment setup. Auto Mode
is not available during Installer Test Mode. If no buttons are pressed for 15 minutes, the installer test mode will be terminated. Pressing
Heat/Cool mode button will stop the test but remain in Output Test mode. Pressing DONE or START at any time will exit installer test mode.
Aux Heat – The first stage of Aux Heat will be energize for three minutes, then the first and second stages (if a second stage exists) will turn
on for an additional three minutes. The Aux Heat icon at the top of the screen will be displayed and a text message on the screen will display
STG 1 and count down from 180 seconds. After three minutes the thermostat will go back to Heat/Cool mode to Off. If no buttons are
pressed for 15 minutes, the installer test mode will be terminated.
Heat – The first stage of heating will be energized for three minutes, then the first and second stages (if a second stage exists) will turn on for
an additional three minutes. During the first stage of heating, the HEAT icon will be displayed along with the text “STG 1”. During the
second stage of heating (if one exists), the “STG 2” text will be displayed if the system has a two--stage compressor (A2, h2, or H2 unit
types). The “auxiliary heat on” icon will be displayed if the second stage is electric heat (HP unit type). While the heating test is active, the fan
output (accessory output on the Côr 7 series) can be toggled by pressing Menu then the up/dn arrows to select.
Cool – Output Test for cooling is the same as described for heating above. The COOL icon and the stage text will be displayed during
cooling in Installer Test Mode. While the cooling test is active, the fan output (and accessory output on the Côr 7 series) can be toggled by
pressing Menu then the up/dn arrows to select and toggle them on/off.
