Pilot Rooms; Parameter "Economy; User Settings And Operating - Rehau NEA SMART 2.0 Service Manual

Case A, transition REDUCED  NORMAL:
Based on the gradient, which is valid at this time due to actual outside
temperature, the system calculates the time which is needed to reach
the desired set point, beginning from the actual room temperature value.
Example for heating mode:
The valid gradient is 0,8 K/h. Actual temperature in reduced mode is
19,4 °C. Set point for NORMAL mode is 21 °C, NORMAL mode shall
start at 7:00 h. This means that heat up starts 2 hours plus a safety
margin earlier.
Case B, transition NORMAL  REDUCED:
The behavior is influenced by a parameter "economy" which determi-
nes the positioning of the system between the extreme positions
"highest comfort" and "most economic".
Depending on this setting the system enters the reduced energy level
sooner or later, allowing a more or less high deviation between set
point and actual value..

Pilot rooms

Rooms selected as pilot rooms (6) impact on
- Heating limit (see chapter 8 Parameter)
- Flow temperature in heating mode (see chapter 8 Parameter)
- Cooling criterion (see chapter 8 Parameter)
The number of pilot rooms is not limited.
Only rooms which are regularly occupied / in use should
be selected as pilot rooms.

Parameter "economy"

The parameter "economy" influences the system behavior in several
points, changing the energy usage and comfort. The parameter can
be modified by user between the values 0 to 10 by the user.
0 – maximum comfort
5 – balanced between comfort and economy (default value)
10 – maximum economy
30
The effects on heating limit and flow temperature are described in
chapter 8 Parameter.

User settings and operating

The user can change set points, operating mode and parameters,
which influence room temperature control, using:
- NEA SMART 2.0 App
- Integrated web pages
- NEA SMART 2.0 Room Units
Only with the NEA SMART 2.0 App is access to the full range of
parameters possible. Important parameters can be modified using the
web pages and only essential parameters can be accessed directly
through the room units themselves.
Using the room units the following settings can be modified
- temporary change of set point:
If the room unit is in TIMER mode, a change in setpoint will only
remain effective until the next programmed temperature change.
- permanent change of set point for NORMAL or REDUCED mode:
If the room is in NORMAL or REDUCED mode, the selected new
setpoint will be remain effective indefinite for the current mode
- change of energy level
Energy level can be changed between:
NORMAL / REDUCED / STANDBY
The selected energy level iremains active until the unit is switched
into TIMER mode and a change in energy level is triggered.
- activation of TIMER program
program)
- activation of PARTY mode:
- PARTY mode uses NORMAL energy level for a time span of 4 h
(default value)
All changes made via a room unit are only effective for
this single room.
