tekmarNet® Thermostat 554 Home Screen
Display of the time, schedule and the away key on the Home screen is optional and can be turned on or off in the programming menus. To enter the programming menus, press and hold the Home button for 3 seconds.
This thermostat displays symbols on its screen to indicate what mode it is in, what temperature it is operating at, or what equipment it is trying to turn on. This section describes each of those symbols.

Note: The temperature is not adjustable if the thermostat is in the Away scene or in the Off mode or has been set to the “Secure” access level by the installer.
Adjust the Temperature — Temporary Hold
Temporary hold allows a user to change the temperature for a period of time and then automatically return to the permanent temperature setting. This is especially useful in commercial buildings that are in use for short amounts of time. When selected, touching the up or down arrows changes the temperature for either 3, 6, 9 or 12 hours. If the thermostat is using a schedule, ‘Schd’ provides a temporary hold until the next schedule event time. After the temporary hold time expires, the thermostat returns to normal operation. By default, the temporary hold feature is off.
This thermostat has 4 operating modes: Heat, Cool, Auto and Off. Touch the Mode key on the screen to select the desired mode of operation.
Auto mode will automatically switch between heating and cooling as required. The temperature is not adjustable while the thermostat is off.
Note: If near freezing temperatures are detected, the system will operate to maintain 40°F (4.5°C), even in the Off mode.
Secondary Temperature Display
This thermostat can display the outdoor or floor temperature or the room heating and cooling temperature settings in the smaller-number area at the top right of the screen. To toggle the item currently displayed, touch the secondary temperature. Display of the floor or outdoor temperature requires a connection to an external floor or outdoor air sensor.

Air Temperature Only
If there is only an air temperature sensor (no floor sensor), the thermostat operates to control your desired air temperature.
Floor and Air Temperature
If the air sensor is turned on and a floor sensor is connected, the thermostat will maintain your desired air temperature as well as a minimum floor temperature.
Controlling temperature this way is recommended for areas with large windows that allow the sun to shine into a room and keep it warm without the need for additional heat. This can allow the floors to cool off during the afternoon. When the sun goes down, it can take a long time for the floors to get warm again and the room may cool off too much in the early evening. A floor minimum setting can help with this condition by maintaining a floor minimum temperature. Keep in mind the floor minimum temperature will override the air temperature, and if set too high, may overheat the room.
This operation is recommended for rooms with hardwood floors, as well as those with large windows. Setting floor minimum and maximum temperatures is a way of enhancing the comfort of your living space while protecting your floor coverings.
