VII.e) Sensors
The submenu Sensors allows the user to adjust the operation parameters for particular zones.
When a given zone reaches the set value, the EU-2640 controller assigns a reheated status to this
zone until the temperature drops below the set value, reduced by hysteresis. When all zones are
reheated, the EU-2640 controller deactivates the pump as well as the dry contact at the same
time.
Submenu in each zone:
Deactivated / Activated
After the room sensor is activated and is assigned a given zone, it will be detected by the EU-
2640 strip. However, the operation of this sensor may be disabled by marking a suitable option.
Set value
The set temperature in a given zone depends on the settings of the selected weekly
schedule. However, the function Set Value allows the user to adjust a separate set value.
After it is determined, the display will show the screen with time settings for this
temperature. After this time expires, the set temperature in a given zone will again depend only
on the weekly schedule. When the duration of a given set temperature is adjusted as 00:00, this
temperature will be valid for an indefinite period of time.
The value of the set temperature along with the time until its end is displayed on the main
screen on a current basis (see Description of the main screen – screen number 8).
Weekly control
The EU-2640 controller has two types of weekly schedules:
1. Local schedule
This is a weekly schedule assigned only to a given zone. After the strip detects the room sensor,
it is automatically assigned as valid in a given zone. It may be edited freely.
2. Global schedule (Schedule 1..5)
These schedules have the same settings regardless of the zone and are non-editable from the
level of the strip (changes in global schedules are possible only via the Internet in cooperation
with an Internet module).
In order to assign the selected schedule to a given zone, the user only needs to mark the
option Select .
If the user wishes only to modify the global schedule as the current one in a given zone,
this is possible in the option Edit . After the user enters the desired modifications and saves them,
it is overwritten as a local schedule.
