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.

Screen Clean Menu
Entering the Screen Clean menu gives you 30 seconds to clean the thermostat and display with a moist cloth. Do not use solvents to clean the thermostat.

Set Temp Menu

Entering the Set Temp menu allows you to permanently change both the daytekmar-552_U-Touchscreen-Thermostat-fig-10 and nighttekmar-552_U-Touchscreen-Thermostat-fig-11 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.

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 tekmar-552_U-Touchscreen-Thermostat-fig-10temperature. 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.
