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.
When the temporary
hold feature is enabled,

Access Levels
This thermostat has access levels. It will typically be installed and programmed by a
heating professional and then locked in a “User”, “Limited”, or “Secure” access level.
System-critical settings are not be available for adjustment. For more information on
these settings, please consult your installing contractor or this product’s Installation
and Operation Manual. This brochure focuses on settings available to the “User”.
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.
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.

Energy savings can be achieved by lowering the heating temperature and increasing

When operating on a programmable schedule, a or a symbol is shown in the

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*)
*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.
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.
