tekmar 552_U Touchscreen Thermostat

This brochure will provide you with the information you need to benefit the most from your tekmarNet® thermostat. Please visit www.tekmarcontrols.com for more detailed information on this or any other tekmar product. This thermostat provides heating for one zone in your building. It will maintain your air temperature with an on board room sensor. Floor temperature control may also be enabled in this thermostat when a floor sensor is installed. This thermostat can lower its temperature setting at night or when you are away from the house.

Touchscreen Adjustments

The touchscreen of this thermostat makes it easy to change commonly used settings. Touch any item to adjust the setting. You will hear a  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 552 Home Screen

Display of the time, schedule, and 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 will display symbols on its screen in order 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 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. This thermostat is capable of controlling the floor or air temperature. When set to control the floor temperature alone, the large display will say instead.

The temperature is not adjustable if the thermostat is in the Away scene, the Off mode or has been set to the “Limited” or “Secure” access level by the installer.

Adjust the Temperature – Temporary Hold
A 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 scheduled event time. After the temporary hold time expires, the thermostat returns to normal operation. By default, the temporary hold feature is off.

Mode Heat or Off Heating
the operation can easily be turned off by selecting the “Off” mode. Touch the Mode key on the screen to change between Heat and Off. The temperature is not adjustable while the thermostat is off. 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, floor or room set temperature 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.

Screen Clean Menu

Set Temp Menu

Entering the Set Temp menu allows you to permanently change both the day and night temperature settings for the room and/or floor. If your thermostat is being used for radiant floor heating, a floor sensor can be connected to it. 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. There are two methods to operating the thermostat using a floor sensor.

Floor Temperature Only 
If the air sensor has been disabled, the thermostat will only maintain floor temperature and ignore air temperature. This operation is recommended for areas such as bathrooms to ensure that tile floors are warm to the touch.

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. This operation is recommended for areas with large windows that allow the sun to shine into a room and keep it warm without the need for 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. This may cause the room to 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 also recommended for rooms with hardwood floors. The floor maximum setting prevents damage to the wood floor from overheating.

Time Menu Settings

Schedule Menu Settings
Lowering the room temperature setting reduces the amount of fuel required to heat the building resulting in energy savings. When operating on a programmable schedule, a or a symbol is shown in the home menu. The or indicates the current operating temperature. All schedules are stored in permanent memory and are not affected by a loss of power.

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

• Turning off the schedule (OFF)
• Operate a schedule that applies only to this thermostat zone (ZONE)
• The ability to operate one of the four system-wide schedules as a master (Schedule Master 1 through 4*)
• Join one of the four system-wide schedules as a member (Schedule Member 1 through 4*)
• 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 four events per day are common for residential use while two events per day are common for commercial installations.

Schedule Menu Settings (Continued)
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 from the temperature to the temperature. The thermostat has the option to use Optimum Start to predict the heat-up rate of the room. When Optimum Start is set to On, the heating is started in advance to allow the room to reach the Set Room temperature at the time set in the programmable schedule.
