Touchscreen Adjustments

The touchscreen of this thermostat makes it easy to change commonly used settings. Touch any item to adjust its setting. You will hear a “tick” sound each time you touch the display. When you are finished making changes, touching the Home button will return to the Home screen. If you do not touch the screen for 3 seconds, the Home screen is automatically displayed.

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.

Display Symbols

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.

Adjust the Temperature

To change the heating or cooling set temperature, touch the or arrows to select a preferred temperature setting. Press the Home button to accept the setting or leave the screen untouched for several seconds. To toggle between changing the heating or cooling setting, press the H <> C key. This thermostat is capable of controlling the floor or air temperature.

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.

Mode of Operation

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.

Adjust the Time 
To change the current time, touch the clock on the display.

• Use the or arrow to change the minutes, hour and day.
• Touch “NEXT ITEM” to advance to the next item or “BACK” for the previous item.

Note: The time is not visible when the thermostat is in the Away scene or if the clock display is turned off in the Time menu.

Programmable Schedule — Day and Night

This thermostat is capable of running at a lower temperature setting when you are asleep or out of the building. When the schedule setting is on, day and night temperature settings will display on the screen. If you adjust the temperature while the sun is displayed, the day setting changes. If you adjust the temperature while the moon is displayed, the night setting changes.
To adjust the times when the day and night temperature start, touch the sun or moon on the screen. “Schedule Menu” will display followed by the first adjustable schedule event time.

• The thermostat schedule can be set to 2 or 4 events per day repeating on a 24-hour or 7-day cycle. These schedule settings are detailed later in this brochure.

Going Away Setting

This thermostat can save additional energy while you are away by lowering the heating temperature and increasing the cooling temperature. To enable this feature, touch “Going Away” on the screen. This is only available when the Away Key has been turned on in the Scene menu.

• Select PERM (permanent) or a number of days using theor arrow.
• Press the Home button to accept the setting or leave the screen untouched for several seconds.

Screen Clean Menu

Set Temp Menu 
Entering the Set Temp menu allows you to permanently change both the day and night temperature settings for both heating and cooling.
If your thermostat is being used for radiant floor heating, a floor sensor can be connected and floor minimum day and night temperatures can be set. Radiant floors heat the air by raising the floor temperature. Setting a floor temperature is a way of enhancing the comfort of your living space.

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.

Time Menu Settings

This thermostat can operate on a programmable schedule in order to automatically lower the heating temperature and increase the cooling temperature setting. Options include:

• Turning off the schedule (OFF)
• Operating a schedule that applies only to this thermostat zone (ZONE)
• Operating one of the four systemwide schedules as a master (Schedule Master 1 through 4*)
• Joining one of the four systemwide schedules as a member (Schedule Member 1 though 4*)
  Note: Requires the thermostat to be connected to a tekmarNet® system.

Once the type of schedule has been selected, the thermostat can support schedules that have either:

• 2 events per day
• 4 events per day
  Schedules with 4 events per day are common for residential use while 2 events per day are common for commercial installations.

The schedules can be repeated every:

• 24 hours
• 7 days (week)

A 7-day schedule allows a unique time to be set to change the temperature for each day of the week.
The schedule also includes a “SKIP” option that allows the programmable schedule to skip a temperature change and remain at the previous temperature setting. The “SKIP” setting can be found between 11:50 PM (23:50 hours) and 12:00 AM (0:00 hours).
When a programmable schedule is selected, there is a time delay for the room to warm up or cool down from the temperature to the temperature. The thermostat has the option of using Optimum Start to predict the heat up or cool down rate of the room. When Optimum Start is set to On, the heating or cooling is started in advance to allow the room to reach the Set Room temperature at the time set in the programmable schedule.
