To change the heating or cooling set temperature, touch the 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.

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

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 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. 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 longtime 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. 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

• Set date, month and year
  • Required for daylight savings time.
• Daylight Save
  • Automatic daylight saving time update for the spring and fall.
• Time Mode

Schedule Menu Settings

Energy savings can be acheived 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, 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 heating temperature and increase the cooling 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 though 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

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 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 temperature at the time set in the programmable schedule.
