Testing the Thermostat Wiring

Testing tekmarNet®2 Wiring ——————————————
Testing the Power
If the thermostat display turns on, this indicates that the thermostat is operating correctly and there are no electrical issues. In the event that the display is off, or the display is cycling on and off:

  1. Remove the thermostat wiring cover.
  2. Check to ensure that the tN2 wires on the thermostat are connected to a zone on a House Control, Wiring Center, or Zone Manager.
  3. Use an electrical meter to measure DC voltage between the tN2 terminals.
    • If the DC voltage is 0 V (dc) for at least 20 seconds, then there is an open or short circuit in the tN2 wires.
    • If the DC voltage is 0 V (dc) for 10 seconds and then is 23 to 24 V (dc) for 5 seconds, this indicates the wiring is correct.
  4. If the thermostat display is off, or is cycling on and off, move the thermostat to the next available zone on the House Control, Wiring Center, or Zone Manager.
    • If the thermostat display remains permanently on, there may be a fault with the previously tried zone on the House Control, Wiring Center, or Zone Manager.
    • If the thermostat display continues to be off or is cycling on and off, there may be a fault on the thermostat.
      If a fault is suspected, contact your tekmar sales representative for assistance.

Sequence of Operation

Heating Operation

Cooling Operation

Room Min and Max Limits

Heating and cooling minimum and maximum temperature settings are available in the Set Temp menu. These allow the installer to select start and stop limits for the temperature settings in both heating and cooling for the User and Limited access levels. This is useful in commercial installations and child/guest bedrooms where the availability of the full temperature setting range may not be desirable.

Mode Operation

The thermostat includes a mode key. Available modes are:

Hydronic Pump and Valve Operation

Fan Operation

The fan operates together with the air heating or cooling systems. The user can also select to operate the fan manually by pressing the Fan button. This allows the user to choose between Auto and On. “Auto” allows the fan to operate together with heating or cooling but normally the fan is off. “On” forces the fan to operate continuously.

Air Group Operation

In order to prevent heating and cooling at the same time, this thermostat can operate together with other thermostats on a tekmarNet® system to form an air group. On older model thermostats the air group functionality was previously described as a cool group. In an air group, one thermostat is assigned as the air group master. The air group master operates the cooling equipment for the group. This thermostat can be set to be a member of the air group. When operating as a air group, the air temperature readings of all the air group member thermostats are communicated to the air group master thermostat and an average temperature is determined. When the air group master is in cooling operation, the air group member thermostats do not operate the heating system for air heating.
When operating a heat pump, the 557 also has the ability to prevent air group member thermostats from heating while the outdoor temperature is between the Warm Weather Shut Down (WWSD) and the Radiant Floor WWSD (W1 WWSD) setting. This allows the air system heat pump to heat the building during mild outdoor weather and avoids heating up the radiant floor slab.
If the Set Heat Room temperature is adjusted while the air group is cooling, COOL is flashed on the display to alert the user that the air group cooling system is presently on and heating is not available. Once the cooling system shuts off, heating is available if required.

Tekmar-554-Non-Programmable-Thermostat-fig.34

Time Clock

The thermostat includes a time clock that is automatically visible in the Home menu when a programmable schedule is used. If the schedule is not used, the user has the option to select whether the time is shown in the Home menu. During a loss of power, the thermostat continues to keep the correct time and date for at least 4 hours. If the power is off for more than 4 hours, the user will need to set the time.
The thermostat supports automatic updates for daylight savings time. Simply set Daylight Save to On together with the correct day, month, and year and the time is automatically updated each spring and fall. When connected to a tekmarNet® system, adjustment of the time on one thermostat updates all connected thermostats. This option can be disabled by selecting the Local Network Group set to be On.

Temperature Adjustment

Permanent Adjustment – No Schedule
When no programmable schedule is used, touch the up or down arrows to permanently set the “Set Heat Room” or “Set Cool Room” temperature. This thermostat is capable of controlling both air and floor temperature.
Permanent Adjustment – With Schedule 
When a programmable schedule is used, there are two room heating temperatures available, one for the time period and another for the time period. When touching the up or down arrows to change the temperature, only the temperature for the current time period is changed.

  1. to adjust the temperature for both time periods, press and hold the Home button for 3 seconds to enter the programming menus.
  2. Enter the “SET TEMP” menu to adjust the following settings:
    • Set Heat RoomTekmar-557_D-Touchscreen-Thermostat-FIG.36 (air heating or air heating with floor sensor)
    • Set Heat RoomTekmar-557_D-Touchscreen-Thermostat-FIG.37 (air heating or air heating with floor sensor)
    • Set Heat Room AWAY (air heating or air heating with floor sensor)
    • Floor Min Tekmar-557_D-Touchscreen-Thermostat-FIG.36(air heating with floor sensor)
    • Floor MinTekmar-557_D-Touchscreen-Thermostat-FIG.37 (air heating with floor sensor)
    • Set Cool Room Tekmar-557_D-Touchscreen-Thermostat-FIG.36(air cooling)
    • Set Cool Room Tekmar-557_D-Touchscreen-Thermostat-FIG.37(air cooling)
    • Set Cool Room AWAY (air cooling)

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.

Tekmar-554-Non-Programmable-Thermostat-fig.35

Programmable Schedules

Energy savings can be achieved by lowering the heating temperature and increasing the cooling temperature when the building is unoccupied or during the night. When operating on a programmable schedule, or a symbol is shown in the home menu. The Tekmar-557_D-Touchscreen-Thermostat-FIG.36orTekmar-557_D-Touchscreen-Thermostat-FIG.37 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:

*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:

Schedules with four events per day are common for residential use while two events per day are common for commercial installations.
The schedules can be repeated every:

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 theTekmar-557_D-Touchscreen-Thermostat-FIG.37 temperature to the Tekmar-557_D-Touchscreen-Thermostat-FIG.36temperature. The thermostat has the option to use 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 Tekmar-557_D-Touchscreen-Thermostat-FIG.36temperature at the time set in the programmable schedule.

Scenes (System Override)

Scenes provide an easy way to save energy while away on vacation, or override a programmable schedule when plans change.

Away Key ———————————————————–
This thermostat includes an Away Key to quickly turn down the heating temperatures and increasing the cooling temperatures on all thermostats and suspend heating the domestic hot water tank to maximize energy savings. To enable, go the the
Scene menu and set Away Key to on.

Secondary Temperature Display

This thermostat can display the outdoor, floor, relative humidity, 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 outdoor or floor temperature sensor, or the thermostat is connected to a tekmarNet® system that includes an outdoor sensor. The reading of the outdoor sensor connected directly to the thermostat takes precedence over any outdoor sensor reading available on the tekmarNet® system.

Tekmar-554-Non-Programmable-Thermostat-fig.37

Access Levels

The thermostat Toolbox menu supports four access levels: Installer (INST), User (USER), Limited (LTD), and Secure (SEC). The access level can be adjusted when the thermostat is unlocked. There are two locations to lock the thermostat:

  1. Locally on the thermostat using the Lock switch located in the wiring area.
  2. Globally on the tekmarNet® system control using the Lock switch or Access level (if installed)

Both the local and global lock settings must be set to unlock before the thermostat access level is adjustable.
The selection of the access level is dependent on the use of the building and the type of occupants.

tekmarNet® Address

When connected to a tekmarNet® system, each thermostat will be automatically given an address. The address is useful as a troubleshooting tool to locate thermostats with errors and also allows room naming on a Gateway.
The address consists of the bus water temperature followed by the thermostat device number. Available buses are b (boiler), 1, 2 and 3. Device numbers range from 01 to 24. If the thermostat is used without a tekmarNet® system control, the bus number is not shown.
When using the thermostat together with a Gateway, it is important that each address be changed to be manually set. This allows each thermostat to be named on the Gateway.
If two thermostats are manually set to the same address, an error message will appear.
The error remains until one of the addresses is manually changed to a vacant address or to Auto.
It is highly recommended to keep a documented list of thermostat addresses. This is extremely helpful when troubleshooting errors. The tekmarNet® system control will display the addresses of thermostats that have errors. By referring to the address documentation, it simplifies the process to locate and correct error messages.

Cleaning the Thermostat

Entering the Screen Clean menu allows 30 seconds to clean the thermostat and display

with a moist cloth. Do not use solvents to clean the thermostat.
