CTC 53300 7-Day Programmable Thermostat

Know Your Thermostat

Your thermostat has been pre-programmed from the factory with no programming necessary. We recommend using these pre-programmed settings for a few days before altering them as they offer maximum energy saving benefits. If you do decide to alter your programs, use the charts on page 13 to write out your scheduled times and temperatures. After you have recorded your preferences, follow the instructions on page 14 to alter your temperature settings. There is no need to program the thermostat at the wall where it is mounted! Remove the thermostat from the backplate by gripping the sides firmly and pulling it straight off. This allows you to program the thermostat in comfort. After you have programmed your thermostat, no other setting changes are necessary unless you wish to browse through the menu to see how you may further adjust the independent settings of your thermostat to meet your lifestyle. The features section starting on page 32 of this manual will describe these settings. Most setting have been preset for optimal performance

The batteries are located in the backside of the thermostat. The thermostat requires 2 (AA) alkaline batteries to operate. If you do not replace the batteries in a timely manner, the screen will go blank except for the low battery warning, (Figure 1b). Your system will shut down and will not operate until you replace the batteries. Replacing the batteries will clear this alert.

• Auxiliary Heat: On multi-stage heat pumps this alert indicates your second stage heat is running.
• Check System: Some heat pump systems are equipped with the ability to check system performance, indicated by the presence of an “L” wire attached to the mounting plate. This icon will flash on screen to alert the user that the heat pump is reporting a problem with the system. It may be necessary to have the heat pump checked or serviced by an HVAC technician

Menu Options

Under your menu options you have the ability to reset your filter counter, change your day/time, span settings, temperature measurement, as well as locking the thermostat. After making changes to each menu option, the thermostat will show “Updated” and save your changes.

To access these options:

• Press the button.
• Once in the menu options list, use the buttons to scroll through the menu items. The Next button will take you into the selected menu item. To escape menu options, press

If “No” is selected, the filter alert will not be reset and will continue to flash on the home screen. Press Next, the screen will flash “Updated” and return to menu options or to return to the home screen.
• Change Date /Time: Next you are given the option of changing your day/ time. You will use the same instructions as on page 10 to change these settings.

The span has been set at the factory to 1 which will allow the system to turn on 1F (0.5OC) above or below the set temperature and run for 1 OF (0.5OC) above or below the set temperature.

Example: If your thermostat is set to turn on at 72O in heat mode, with a span setting of 2, your thermostat will activate your furnace at 70O and shut it down when it reaches 72O. For cooling at 72O with a span of 2, your air conditioner will activate at 74O and shut down at 71O. This setting can be changed to 1, 2, or 3. 1 will shorten your running time while 3 will lengthen it.

Press once this has been changed or if you need to make no changes. The second stage span acts the same as your primary, but it determines when and how long your second stage heat runs.

Energy Saver Bar

The Energy Saver Bar indicates estimated energy savings. The preset schedules in the thermostat have been designed to give you optimal energy savings, five bars. Altering these schedules has a direct impact on the energy saver indicator. Altering the temperatures and/or times that the schedules run could decrease the estimated energy savings.

• Example 1 shows the thermostat running the default schedules in the thermostat.
• Example 2 shows the thermostat running altered schedules. This example could indicate the “At Home” schedule running for a longer time frame, or the temperatures may have been altered to where there is less of a gap between the
• “At Home” and “away” or “Asleep” temperatures.

Note: The Energy Saver Bar is only to be used as a guide to potential energy savings. Due to varied energy consumption costs, regional temperatures, and personal comfort levels, this bar cannot be equated into actual dollar or energy amounts
