Operation Guide CT80

The CT80 programmable communicating thermostat operates via a high-quality, easy-to-use touch screen. To program or adjust your CT80, simply touch your finger firmly to the screen. The screen will automatically light up. The screen will respond differently to different types of touches, so you may want to experiment with your finger or a stylus (not included), to see what works best for you.

The “beep” sound is heard when the CT80 senses a valid touch of the screen.

Temperature. The system will HOLD this temperature until you return to this screen and de-select HOLD, by touching it. (HOLD is also canceled when you change the mode ).

HOLIDAY PROGRAM - This is a single program that repeats day after day until you turn it off. It supersedes the weekly program. To modify it touch PROGRAM on the MANUAL screen. It uses the

Calendar method for programming (see pg7 ).

VACATION - This function will hold a pre-set temperature until you turn it off. The preset is saved for next time.

FRESH AIR - If you have a fresh air baffle connected to the EX terminal, the CT80 will use this outside air source as the 1st stage of heating or cooling. Useful in desert climates where outside air temp can change very quickly or just to freshen indoor air quality.

EMER HEAT - This is available if you have a HEAT PUMP with auxiliary heat. When you select this your HEAT PUMP is disabled and auxiliary heat is your sole source of heat. This manual override setting stays active until you turn it off. (This command is not displayed if you do not have a heat pump). Remember auxiliary heat is more expensive than the heat pump.

Run the pre-set program

The CT80 comes pre-programmed with an EPA approved program. This program was recommended by the EPA for energy efficiency. We strongly recommend that you run this program for one week, and see if it works for you. If it does not fit your needs you can always input a custom program.

• To run the EPA program, press and select HEAT or COOL with the mode selection. Set the time and day and Press HOME. The unit is now running the EPA program.

COMFORT

The Comfort Settings on the CT80 allow you to maintain consistent comfort with the highest levels of temperature control precision, accuracy and energy efficiency.

HVAC CYCLING: This feature allows you to set the desired variance in temperature between the

CT80 setting and the room temperature required before the heating or cooling system will turn on— from 0.5° to 3.0° F (.25° to 1.5° C). For example, if HVAC CYCLING is set to 2.0° F and the CT80 is set to 70°F, the heat cycle will not start until the room temperature drops to 68°. Similarly, the cooling system will not kick-in until the room temperature increases to 72°F. The HVAC shuts off at the target.

To set/adjust HVAC CYCLING:

1. Press Menu and then touch “COMFORT.”

2. Touch the temp offset setting.

3. Use the +/- buttons to raise or lower the variance setting—from 0.5° to 3.0° F.

4. Press HOME to return to the Home screen.

2nd STAGE ON AT : This feature allows you to adjust the settings that control the next stage heating, cooling, and AUX depending upon the climate you live in (see page 18 for more information). This can be modified for maximum efficiency or comfort. It is displayed for a multistage system in HVAC SET-UP.

To set/adjust 2nd STAGE ON AT:

1. Press Menu and then touch COMFORT

2. Touch and highlight the user setting (next to 2nd STAGE ON/AUX ON AT ).

3. Use the +/- buttons to raise or lower the setting—from 2.0° to 6.0°F (1.0° to 3.0° C).

The “NEVER” option allows the user to not use AUX heat except for EMER.

4. Press HOME to return to the Home screen.

RECOVERY - ECON or FAST - In multi stage HVAC systems, ECON takes a bit longer but uses less energy to get to the Target Temp. FAST recovery uses all available stages all the way to target temp and uses a little more energy (see page 18 for more information).

Chirp set - Touch this to turn the audible chirp sound on or off.

F/C Set - Touch this to switch the temperature display scale from oF to oC .

HUMIDITY

The CT80 has a humidistat to control an external humidifier for humidifying by the H terminal.

HUMIDIFR - To set a minimum humidity level (with a humidifier installed in the HVAC) from the HOME screen:

1. Press MENU, then touch the HUMIDITY

2. Toggle HUMIDIFR from <OFF> to <W/ HEAT>.

3. Touch MIN 20% and use the +/- buttons to set the desired minimum humidity level.

4. The CT80 can be toggled <ALWAYS> run the humidifier when the humidistat calls for humidity (in

HEAT or cool with fan) or can be set to run only when the humidistat is calling for humidity and the heat is also running <W/ HEAT>.

(You cannot change MAX humid % until you set it to ALWAYS or HST+TST)

3. The CT80 can be toggled to <ALWAYS> run the air conditioner when the humidistat calls to dehumidify or can be set to run the air conditioner only when the humidistat calls to de-humidify AND the thermostat is also calling for COOL <HTS+TST> (HST=humidistat, TST=thermostat).

EXTERNAL DE-HUMID - The CT80’s humidistat can also control an external de-humidifier (heat or cool), if you have a dehumidifier unit installed in your HVAC system. Connect it to the DH terminal.

Default operation is to run the fan [G] with the external de-humidifier (with fan/without fan is selectable).

To set a maximum humidity level:

1. Press MENU, then touch the HUMIDITY.

2. Touch MAX --% and use the +/- buttons to set the desired maximum humidity level.

3. Press HOME to return to the HOME screen.

CONSUMABLES

Consumables are parts of your HVAC system that get used up; like filters and

UV bulbs. The CT80 keeps track of system run times and can be programmed to remind you when consumables, such as air filters, humidifier pads and UV bulbs, should be checked and/or changed.

(HUM PAD = Run time of humidifier, AIR FILTER = Real time of HEAT+COOL, UV BULB = Real time)

To set/adjust CHECK CONSUMABLES ALERTS:

1.Press Menu and touch CONSUMABLES, and select a

CHECK ALERT to set.

2.Touch the number of days in the CHECK ALERT column for that item, and use the +/- buttons to raise/lower.

- Alerts may be scheduled from 0 to 999 days.

3. Repeat for each item included in your system.

- If your system does not include a listed item, leave the

CHECK ALERT at - - days.

4.Press HOME to return to the Home screen.

When the Run Time for a given item reaches the limit you have set, the CT80 will show you a reminder in the

INFORMATION

This MENU function displays

information and interactive screens from a network source. The network can display interactive information screens, poll users, and display electrical rate and usage information from your utility or enabled power meter.

Home automation systems can also utilize the INFORMATION function for interactive and informative messages. They can display text and alpha numeric information on energy use,

HVAC status, and other network connectivity.

These messages are generated by another network source and displayed on the CT80.

Consult your AMI or Home Automation network documentation for further information.

Communicating Thermostat -

The CT80 has 2 RTM-1 radio ports. These allow your thermostat to communicate with other systems. Alarm systems using the Z-Wave standard take advantage of the CT80s control and monitoring features.

Depending on your area Power Company, programs may be available to connect your thermostat to power grid status information. This can make it easy for you to moderate your energy use at peak hours and use power when it is less expensive.

The RTM-1 ports also allow you to connect your CT80 to your home WiFi network. This can give you access to your home’s HVAC system even when you are away. It can also give you access to web based efficient energy management sites that can help you save money and protect the environment.
