EU-2640 user’s manual
13
The type of weekly schedule assigned to the zone is visible on the main screen (see Description
of the main screen – screen number 9).
Edit
The schedule's editing commences after the user marks the option Edit .
The user may program no more than three time intervals with specific boundaries (with
accuracy to 15 minutes). A separate set temperature is assigned to each interval. The next step
is the adjustment of the set temperature valid beyond the time intervals.
The last step is selecting days of the week on which these settings are to be valid: by means of
the button
, the user proceeds to edit the neighboring day of the week and it is marked /
unmarked with the use of the key .
Correction
The room sensor is calibrated during the installation or after a longer period of the regulator's
operation if the displayed external temperature differs from the actual temperature. Adjustment
range: -10 to +10⁰C with accuracy to 0.1⁰C.
Hysteresis
Hysteresis introduces the tolerance for the set temperature preventing unwanted oscillations at
minimum temperature deviations (ranging from 0 ÷ 10⁰C) with accuracy to 0.1°C.
Example: when the set temperature is 23⁰C and the hysteresis is adjusted to 2⁰C, the zone will
be assigned a status of insufficient heating after the temperature in the room drops to 21⁰C.
Registration
When wireless temperature regulator actuators are used, it is necessary to register a given
actuator in the zone. The user may select 8 zones (Valve 1…8), no more than 9 actuators may be
registered in each zone.
The registration process:
1. The temperature regulator actuator is mounted on the heater, the user waits until it is
calibrated (the calibration process ends with a short, double acoustic signal)
2. The user selects the number of the zone in which they wish to register a given actuator
and then the option
Registration / Register Valve .
3. The user presses the registration button on the actuator. This needs to be done within
30 seconds from pressing the option Register Valve – after this time,
the EU-2640 controller considers the registration process
unsuccessful.
4. If the registration is conducted correctly, an appropriate message
will appear on the display informing about the successful
registration, as well as informing about the number of registered
valves. In the case of an error in the registration process, an
appropriate message will appear on the display. There are three
possible causes of errors:
a. Attempt to register more than nine actuators.
b. Attempt to register an already registered actuator.
c. No signal from the valve actuator within 30 seconds.
A digit informing about the number of registered valves is displayed apart from the icon Register
Valve.
