1 General information
This document is not a comprehensive technical data sheet; rather, it describes the main steps to be taken in order to operate a Sauter ecoUnit1
room operating unit as a uni-directional unit.
The profile in this operating mode is EPP*: A5 -10 -01
In addition, two PTM buttons are available on the EY-RU146 (EEP*: F6 -02 -01).
*EEP V2.61
The ecoUint110 room sensor is pre-set to uni-directional operating mode and the default values cannot be changed because
there is no LCD.
2 First steps
2.1 Uni-directional operating mode
The ecoUnit1 room operating unit has to be configured appropriately to set it to uni-directional operating mode,
i.e. configuration identifier 5 must be set to a value of 01...04.

digit 1: Configuration identifier
digit 2: Prefixed sign(-)

The following table indicates the meanings of the possible configurations. The identifiers (6-9) shown in this table
are valid only for the uni-directional mode.
5Select/block function(s) for buttons 1 to 6 (only ecoUnit144 and
ecoUnit146)
00 (bi-directional mode) default ecoUnit14x
Uni-directional modes:
01 only dXs (default for ecoUnit110)
02 dXs + occupancy function
03 dXs + fan function
04 dXs + occupancy + fan
6Select display for actual value °C or °F 00 = °C (default)
01 = °F
7Display and setting range for setpoint correction (max ± 9.9 K)
Display without °C or °F (- 9.9 °...+ 9.9 °)
00...99 ± 9.9 K
20: - 2.0 °...0.0 °...2.0 ° (default)
8Resolution of setpoint correction range
(number of stages based on 0...max. value)
Transmission of setpoint correction is defined as unsigned number
0...255. The set resolution changes in value each time the button is
pressed: Value = 255/ (2x resolution)
00...99
Default 04 = 255 / (2 x 04) = 32
Example of default setting
(configuration identifiers 7 + 8)
Displayed range 20: -2.0°...2.0°
Resolution 04: The range 0...2.0°C is divided into 4 stages
Display: -2/-1.5/-1/-0.5/0/0.5/1/1.5/2
Value transmission (approx.): 0/32/64/128/160/192/224/256
9Correction value: Calibrate displayed value (Xi); the correction value is
added to the measured actual value. The device sends Xi plus measured
correction value.
00...99 0.0...9.9 K
Digit 2 = prefixed sign (–)
Default 0: 0 K
AShow setpoint correction with or without unit 00 Display with unit
Setpoint correction is displayed with the unit °C or °F
01 Display without unit
Setpoint correction is displayed without unit. Only the numerical value is
shown.
Default 0: Display with unit

The following table describes the procedure for changing the configuration:
Step Action
1. Switching to configuration mode • Press and hold down button 6 for at least 7-10 seconds; it then changes to the configuration mode.
During this time, the display is turned on for approx. 5 seconds, then it remains off for 2 - 5 seconds
before switching to configuration mode.
• Digits “XXX” are shown (1. Position = configuration identifier,
positions 2+3 = set value).
• Starting from now, button 1 or 6 must be pressed within 10 seconds, otherwise the device will
automatically switch back to the operating mode.
2. Selecting a configuration
(digits 1...9)
5 00 > 7 s
> 1 s
• You can now select the required configuration identifier using button 6 (= increment), button 1 (=
decrement). The buttons should be pressed for longer than one second.
• After the highest configuration identifier is reached, the display automatically switches back to
identifier 0.
• If identifier 0 is shown and you switch back to the preceding identifier, the highest identifier is shown.
• To switch to the uni-directional operating mode, configuration identifier 5 must be selected.
3. Changing the configuration value
5 00 < 1 s
< 1 s
• You can change the current value with button 6 (= increment) and button 1 (= decrement); to do this,
press the buttons briefly, i.e. for less than one second.
• Press button 1 or 6 for approx. 2 seconds to switch to the next or previous configuration identifier.
• The function selection 01...04 can now be set for the uni-directional mode.
1 18 > 7 s

4. Saving the configuration and exiting the
configuration mode
> 5 s
• Press button 1 for approx. 5 seconds. The previous configuration identifier is displayed for approx.
2 seconds. The display is then switched off. The data has now been saved and you can release the
button.
5. Exiting from configuration mode without
saving data
• If no button is pressed for approx. 10 seconds, the system switches to operating mode automatically.
Any changed data will not be saved.
