• Weekly control
The controller off ers two types of weekly schedules:
Own – local schedule
This weekly schedule is assigned to a given zone only. After the room sensor has been
detected by the external controller, the schedule is activated automatically in this zone and
may be adjusted by the user to individual needs.
1..5 schedules – global schedule
These schedules have universal settings for all zones and they cannot be edited in the
external controller (to introduce changes it is necessary to connect to the Internet via the
Internet module or UFHTFTM).
In order to assign a schedule to a given zone, choose Select option.
In order to adjust the global schedule as the current schedule in a given zone,
choose Edit option. After the schedule has been modifi ed and saved, it is overwritten as a
local schedule.
The type of weekly schedule assigned to a zone is displayed in the main screen (See: Main
screen description – screen area no. 9).
Edit
In order to start editing, select Edit option.
The user may program up to 3 time periods with pre-defi ned time limits (with the
accuracy of 15 minutes). Separate temperature value is assigned to each time period. The
next step involves setting the temperature value to apply outside the time periods (setback
temperarture).
The last step involves choosing days of the week when the settings should apply.
Use ▲ to edit the next day and press ▼ to select/deselect.
• Calibration
Room sensor calibration should be performed while mounting or after it has been used
for a long time, if the external temperature displayed diff ers from the actual temperature.
Calibration setting range is from -10˚C to +10˚C with the accuracy of 0,1˚C.
• Hysteresis
This function is used to defi ne tolerance of the pre-set temperature in order to prevent
undesired oscillation in case of small temperature fl uctuation (within the range 0 ÷ 10⁰C)
with the accuracy of 0,1°C.
Example: if the pre-set temperature is 23⁰C and the hysteresis is 0,5⁰C, the zone
temperature is considered too low when it drops to 22,5⁰C.
