FUNCTION
The room thermostat regulates heating and/or cooling in a room via digital outputs on/o for
valves in 2 or 4 pipe installations and for 3-speed fan control. The touch screen shows the
actual operating state and is also used to access all parameters, such as setpoint, hysteresis,
fan speed etc. The unit has a built-in room temperature sensor. The change-over (between
heating and cooling at 2 pipe installation) can be controlled by selecting the mode on the
display or via a digital input connected to any potential free contact (e.g. heat pump in COOL
mode). Functions such as mould protection and automatic valve exercise ensures a proper
functionality and a problem free work over the time.
HANDLING
The display behaves dierently depending on the mode and the state that the controller is
currently operating in. The thermostat can be in one of the following states:
• O: Energy stop state where the controller neither heats nor cools. No background light is lit,
only the On/O button is shown and usable.
• Occupied: Comfort (Standard) state or if a presence detector is connected and someone is in
the room. Optimal heating and cooling takes place.
• Standby: Energy saving state where reduced heating or cooling takes place.

Symbol Description
On/O button
Arrow up = increase button for
setpoint adjustment + for start parameter list: press
both together until the display
shows 0000, then short “up” to
show P001
Arrow down = decrease button for
setpoint adjustment -
Changeover button to switch between heating and cooling via the
display
Fan button to regulate the fan speed via the display between AUTO /
MAN (o/1/2/3)
The display can be in 3 modes, when controller state is
Occupied or Standby :
• Active mode: The controller is activated, but no changes are made now. The display shows either
the current room temperature (standard) or the calculated setpoint (if parameter P045 is set to 0).
• Setpoint mode: This mode is activated when pressing one of the arrows when in Active mode.
Either the calculated setpoint ± adjustment (standard) or the current user defined setpoint
adjustment (if P046 = 1) are shown.
• Idle mode: The controller has been inactive during a set time span (activatable with P044 > 0
seconds). All buttons and segments, except the two arrows, are dimmed down in the display.

INSTALLATION
1. Install the attached clamp-on temperature sensor at the supply pipeline from the heat pump.
Extend the cable if necessary up to 50m with J-Y(St)Y 2x2x0,8.
2. Separate the back plate from the display part with a small screwdriver. Insert him in the
grooves at the bottom of the display part and turn it slightly.
3. Connect the wires to the terminals.

Standard 2-pipe installations (see manual for optional 4-pipe installations):
4. Place the back plate over the electrical wallbox and fasten it on the wall using the mounting holes.
5. Clip the display back on to the back plate. Switch on the power supply. Controller starts in
O state. Press On/O button to switch to On state.

SETTINGS
Starting from display is in active mode, the controller settings can be edit in the following way:
1. Press both arrow buttons together until the display shows 0000.
2. Then press short “up”, to show P001 = Parameter 1.
3. Use “up” or “down” to step through the parameter list.
4. Press shortly the On/O button to go in edit mode. Setting value is shown and flashes.
5. Edit the value by arrow buttons “up” or “down”.
6. Confirm your edit with press the On/O button. Display jumps back to the parameter
number.
If the display is left in the Parameter menu for more than 10 seconds without any activity
(buttons pressed), the controller will automatically exit the parameter menu. The parameter
menu can also be left, with the selection of “EXIT” and confirm with On/O.

ERROR MESSAGES
The controller shows an error message, if the measured temperature is outside the limits or
there is no connection to the sensor. The following messages may appear:
Value Description To do
LO Measured value at AI less than low limit 0°C check the temperature of the pipeline and
the value of the disconnected sensor (must
be between 1kΩ and 1,309kΩ)
HI Measured value at AI exceeds high limit 80°C
ERR Error: short circuit or open connection at AI check the cable between controller AI
