This thermostat provides heating and cooling 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.

Display of the time, schedule and the 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

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.

Adjust the Temperature

To change the heating or cooling 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. 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.

Note: 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.

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, 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 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. Setting floor

minimum and maximum temperatures is a way of enhancing the comfort of your

living space while protecting your floor coverings.

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.
