Temperature Adjustment Section I
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 Room (air heating or air heating with floor sensor)
Set Heat Room (air heating or air heating with floor sensor)
Set Heat Room AWAY (air heating or air heating with floor sensor)
Floor Min (air heating with floor sensor)
Floor Min (air heating with floor sensor)
Set Cool Room (air cooling)
Set Cool Room (air cooling)
Set Cool Room AWAY (air cooling)
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.
