H. Automatic CH Temperature Control (AUTO)
The Automatic Temperature Control (AUTO) function allows the boiler
to automatically adjust the target temperature of each heating zone to
adapt to outdoor and/or indoor temperature conditions and/or heat
demand cycles.
Select the type of Temperature Control via parameters 4.2.1 (Zone 1),
5.2.1 (Zone 2), or 6.2.1 (Zone 3). The default setting is 3 - Outdoor Reset.
See Table 28.
NOTE: Automatic Temperature Control is only possible when the AUTO
function is turned ON. To activate the AUTO Function, set to “ON” via
the User Menu, or set parameter 2.2.4 = 1 via the technical menu.
In order for the boiler to detect changes in room temperature it is
necessary to install an NTI Room Sensor. Other thermostats (not
NTI) can only switch the boiler ON and OFF.

4.2.1 Type of Temperature Control*
0 = Fixed Outlet Temperature - Automatic Temperature Control (AUTO) OFF
1 = Basic Temp. Control (without Optional Room Sensor or Outdoor Sensor)
2 = Indoor Temp. Reset (With Optional Room Sensor)

4.2.2 Slope of Outdoor Reset Curve 0.2 - 3.5
The greater the slope, the quicker the boiler target
temperature rises as the outdoor temperature decreases.
Applicable when 4.2.1 = 3 or 4.
1.3
4.2.3 Parallel Shift of Reset Curve
-12 to +12 (when 4.2.0 = 0)
-25 to +25 (when 4.2.1 = 1)
Provides a means of adjusting (shifting) the calculated reset
boiler target temperature up or down. Applicable when 4.2.1
= 1, 2, 3, or 4.
0
4.2.4 Room Sensor Influence 0 - 20
Adjusts the influence of room temperature on target boiler
temperature - a higher setting causes a greater increase to the
boiler target temperature as the indoor temperature drops
below room setpoint. Applicable when 4.2.1 = 2 or 4.

4.7 Zone 1 Regulation Parameters
4.7.5 Auto Boost
0 = OFF
1 = ON
When ON, the boiler automatically adjusts the slope based on the 4.2.2 parameter
setting. The slope increases 10% for every 10 minutes a call for heat is active, and
decreases 1% every minute after the call for heat has been satisfied.
