You have opted for a Sauter control unit, a quality product from a leading manufacturer of control devices for heating, ventilation
and air conditioning.
Your new device features simple operation in connection with advanced micro-processor technology. Please follow operating
instructions for adapting the device to your specific system and requirements
.
Due to its automatic change-over between summer and winter modes (and vice-versa), its automatic weather compensation and
adaptation to building characteristics and heating systems, the individually programmable time programs for controlling the nightly
temperature reduction, domestic hot water charge etc, optimisation of ON/OFF switching time sections for normal and nightly tem-
perature and controlled booster pre-heating mode, this device enables consequent energy saving programs to be implemented
while simultaneously ensuring high comfort. The quartz clock of the controller has an automatic summertime/wintertime change-over
system and works without environmentally unfavourable batteries or accumulators.
Due to a high flexibility of the input and output configuration, this controller can be adapted perfectly to different types of heating
systems; demand-led heating circulation pumps (with speed reduction control), domestic hot-water charge pumps and general circu-
lation pumps can be controlled in addition to one or two three-point control valves. The controller measures all parameters relevant
for an efficient heating system control by means of up to eight "Nickel 1000" temperature sensors and additional special inputs for
flow measurement with three optional methods.
The controller can be configured and programmed on site without any additional accessories; it can also be adapted to an extended
range of tasks at a later time.
The exceptionally high number of functions includes safety features such as the system frost-protection function which is activated
in OFF mode, standstill-damage protection of the circulation pumps during summer, anti-legionella function for hygienically unob-
jectionable hot water, minimum and maximum limitation of temperatures and flow, etc.
With the optional remote control accessory, the heating controller can be operated from up to two independent homes or offices.

The information centre (LCD)
This display unit provides information on the current operating status of the heating system. Flashing symbols prompt parameter
entry or indicate a special operating condition and are designated with the symbol in the following text. means factory
setting of the controller.
Heating modes
If no "upper" clock symbol is shown in conjunction with the
display of the current operating mode, this indicates either con-
tinuous operating of heating circuit 1 or timer-controlled opera-
tion.
When 2 heating circuits are configured, the operating mode of
the second heating circuit will be indicated by a flashing symbol
if different from the operating mode of the first heating circuit.
The "upper" clock symbol is only displayed for heating
circuit 1.
Operating modes for domestic hot water
If no "lower" clock symbol is shown in conjunction with the
display of the current operating mode, this indicates either con-
tinuous operation of the domestic-hot-water system or timer-
controlled operation.

Selecting the operating mode (heating and domestic hot water)
By pressing one of the keys shown below, you can select the following modes of operation:
The clock symbol is never used for heating circuit 2; here only
the current operating mode is displayed. A flashing operating
mode symbol ( , , ) always refers to heating circuit 2. If
the operating modes ( , , ) are the same for both heating
circuits, the corresponding symbol is shown continuously.
If, in addition, a remote control device is installed, this device will
only act on one heating circuit. An additional remote-control unit
must be installed for the second heating circuit, if required. Re-
mote control has priority only when the controller is in automatic
mode PRO 1 or 2.
Automatic mode:
Heating operation and enabling/disabling the charge of domestic water is controlled according to
the time program as specified in PRO 0...2. If further time channels have been configured in PRO 0...2, they will
also be operated according to this time program.

normal operation (upper symbol disappears from the display)
If an additional heating circuit is installed, the operator must specify whether the entry is valid for heating
circuit 1 or heating circuit 2 after pressing the key.
This is effected by means of key for heating circuit 1 or for heating circuit 2.
The operating mode of the heating circuit not addressed by the entry remains unchanged.
If the key is pressed instead of or , both circuits will be switched to winter operation.
Heating system in
continuous
reduced operation (upper symbol disappears from the display)
If an additional heating circuit is installed, the operator must specify whether the entry is valid for heating
circuit 1 or heating circuit 2 after pressing the key.
This is effected by means of key for heating circuit 1 or heating circuit 2.
The operating mode of the heating circuit not addressed by the entry remains unchanged.
If the key is pressed instead of or , both circuits will be switched to winter operation.
Heating

frost protection function
will reliably prevent damage to the heating system when outdoor temperature drops below freezing point.
If an additional heating circuit is installed, the operator must specify whether the entry is valid for heating
circuit 1 or heating circuit 2 after pressing the key.
This is effected by means of key for heating circuit 1 or for heating circuit 2.
The operating mode of the heating circuit not addressed by the entry remains unchanged.
If the key is pressed instead of or , both circuits will be switched to summer operation.

Short interruption of the weekly heating program
After the switching command (in our example at 10:00 pm) following A, the heating operation will return to the weekly program.
Party function
(Please note: The switching command 7 23:30 has been entered in addition to the factory-set weekly program)
(without previous actuation of or ) results in a RESET
command for the party function and the short-term absence/pre-
sence function. These two functions can only be activated for
heating circuit 1 and 2 if the selected heating circuit is in winter
operation and operation is controlled by the weekly program.
When operation is controlled by the weekly program, the operating mode can be changed until the next switching com-
mand is released. The operating modes are switched according to the symbols printed on the keys.
If a second heating circuit is installed, the operator must specify whether the entry is valid for heating
circuit 1 or heating circuit 2 after pressing the yellow key. This is effected by means of key for heating
circuit 1 and for heating circuit 2.
Example: 0 06:00 , 0 22:00 ; the house is left at time A with the intention of returning late at night.

Adapting the heating characteristic
A properly adapted heating characteristic results in a constant
room temperature even with varying outdoor temperatures. The
factory settings of the controller heating characteristic are de-
signed for an average building with radiator heating. If no room-
temperature sensor is available or if the reference room is not
typical for the entire building, the heating characteristic can be
adapted
manually
(see below for automatic correction). If the
set normal temperature (user adjustment value PAR no. 1) is not
reached after a couple days, corrections can be entered as fol-
lows (example for heating circuit 1):
Correct: PAR no. 1 in steps of 0.5 °C max. and PAR no. 3 in
steps of 0.05 max. until the desired normal temperature is
reached. If possible, introduce only one change per day in order
to give the building time to adjust to the new condition.
If there is a second heating circuit, the same applies with the ap-
propriate parameters:
PAR 7 = normal temperature of heating circuit 2
PAR 9 = curve slope of heating circuit 2
and for the corresponding SERV adjustment values.
If a room-temperature sensor is available in a typical room
(reference room) of the building, an
automatic
adaptation of the
heating characteristic can be triggered via setting value
SERV 88.
It is essential for this mode that any thermostat valves installed
in this room remain in their fully open position.
By means of the measured deviations of the room temperature
from the corresponding setpoint and the average outdoor tem-
perature calculated for the measuring period, the system will
either.
adjust the slope of the heating characteristic (PAR 3);
or
adjust the curvature factor of the heating characteristic
(SERV 66);
or
shift the base point of the heating characteristic
(= external heat supply) horizontally.
The number of adaption steps executed is shown under
SERV 88
The automatic adaption of the heating characteristic parameters
is executed with high weighting factors for the first adaption steps
(if a deviation has been detected) and with reduced weighting
for the subsequent adaption steps.

Adapting the normal-temperature setpoint
Normal temperature can easily be changed by pressing the keys shown above (see also PAR 1 and 7). If a second heating circuit
is installed, the operator must specify whether the entry is valid for heating circuit 1 or heating circuit 2 after pressing the
yellow key. This is effected by means of key for heating circuit 1 or for heating circuit 2.
Example:
Use these keys when the heating characteristic is adjusted properly and the normal temperature is to be increased or reduced
(please refer also to the section on remote control EGS 52/15)
Tips for energy saving
Your heating system controller has been designed according to
state-of-the art principles of energy saving. Your management
of the heating system is, however, also important.
The highest savings are possible when the heating
system is switched off during the night. Normal buildings
(of medium-heavy construction and average-type insu-
lation) cool down by 2...3 °C when the heating is
switched off for between 8 and 10 hours. Try to comple-
tely switch off the heating system over night ( instead
of reduced operation ). The integrated frost protection
function will reliably prevent freezing of system compo-
nents.
Can the switching times of the weekly program for or
operation be advanced?
Heat to temperatures between 19 °C and 21 °C.
Each additional degree increases the heating costs by
approx. 6 %.
Air the rooms only for short periods (5 min) but with wide
open windows and, if possible, across the room.
The radiator-thermostat valve can be partially closed in
rooms not being used for a considerable period of time
(except for the reference room).
Close window shutters and curtains at night.
Curtains hanging over the radiators reduce their efficien-
cy and result in increased energy consumption.
Switch the heating system to reduced temperature ( )
or OFF ( ), when you leave the house for several
hours. Use the short-term absence key for this
purpose.

PRO time programs
Dependent on the corresponding system configuration, the com-
ponents of the system can be controlled individually. By pressing
one of the yellow keys of the user keypad, the controller is
switched to the corresponding continuous operating mode (refer
to the section on operating mode selection). The controller nor-
mally operates in mode. By suitably programming the time
programs PRO 0...2, several components of the system can be
triggered once (timer) or repeatedly (weekly and annual pro-
grams). The operating status of the system can be influenced
by several sources in the following manner:
Possible conflicts between the individual sources are solved by
different priorities assigned to the sources (Example: annual
program specifies: heating circuit 1 ON, weekly program spe-
cifies: circuit 1 OFF; the annual program has higher priority than
the weekly program, therefore heating circuit 1 is switched ON).
The timer has the highest priority; it can therefore not be inter-
rupted by the continuous operating mode (disabling is, however,
possible with PRO 0 = 000 (h)).
The controller has 3 time programs:
PRO 0: 1 timer (hourly count-down)
PRO 1: 1 weekly program with a maximum of
40 switching commands
PRO 2: 1 annual program with a maximum of
28 switching commands
