Commissioning
1 Mounting
Remove controller from its base by proceed according to
Fig. A.
For mounting, refer to Figs. B and C and "Mounting notes".
2 Check wiring
For the electrical connections, refer to "Connection
diagram" (also refer to Figs. D and E).
Note: Do not use stranded wires, only solid wires or
stranded wires with ferrules.
3 Remove the battery transit tab
As soon as the battery transit tab is removed, the controller
starts to operate (also refer to Fig. F).
4 Configuration
4.1 Accessing the heating engineer level
The heating engineer level will be enabled by pressing
simultaneously the warmer and colder buttons and by
turning the setting knob counter-clockwise and then
clockwise (also refer to Fig. H).
4.2 Functions
4.2.1 Calibrating the temperature sensor
After activating the heating engineer level, the CAL symbol
will flash. When pressing the OK-knob, the room
temperature currently measured flashes and can now be
recalibrated by a maximum of ± 2 °C by turning the setting
knob. To store the recalibration, press the OK-knob
(also refer to Fig. ).
4.2.2 Setpoint limitation
There are 2 setting choices available:
or
On the heating engineer level, change from the flashing
CAL symbol to the setpoint limitation symbol by turning the
setting knob clockwise (also refer to Fig.
Press the OK-knob to accept. 5...29 °C will flash (factory
setting). Press the OK-knob to accept or continue turning.
Setting 16...29 °C will flash.
Press the OK-knob to accept.
4.2.3 Optimum start control
On the heating engineer level, change from the flashing
CAL symbol to the optimum start control symbols
by turning the setting knob
clockwise (also refer to Figs.
Press the OK-knob to accept.
will flash, optimization is switched off. Press the OK-knob to
accept or continue turning until you reach ¼ h/°C,
½ h/°C or 1 h/°C. Press the OK-knob to accept.
4.2.4 Control mode
On the heating engineer level, change from the flashing
CAL symbol to the symbols of the various control modes by
turning the setting knob (also refer to Fig.
Press to accept. (factory setting) will flash. Press the
OK-knob to accept or continue turning the setting knob to
select one of the following control modes:

, PID 6, PID 12 or
accept the required control mode.
A brief description of the control modes is given below (also
refer to Fig. ).
Self-learning
Adaptive control: Suited for all standard
applications.
PID 12 Normal controlled systems:
For locations with normal temperature variations.
PID 6 Fast controlled systems:
For locations with significant temperature
variations.
Difficult controlled systems:
Proper on / off controller with a switching
differential of 0.5 C.
(factory setting)
4.2.5 Periodic pump run
This function protects the pump against seizing during
longer off periods. Periodic pump run is activated for one
minute every 24 hours at 12:00 (when pump run is activated,
the flame symbol appears on the display).
On the heating engineer level, change from the flashing
CAL symbol to the symbol by turning the setting knob
(factory setting, periodic pump run off). Press to accept.
will flash (factory setting). Press the OK-knob to accept
or continue turning the setting knob. The
periodic pump run on will flash. Press the OK-knob to
accept (also refer to Fig.
4.2.6 Heating / cooling mode
On the heating engineer level, change from the flashing
CAL symbol to the heating / cooling symbols by turning the
setting knob.
Press the OK-knob to accept, the
flash (factory setting). Press the OK-knob to accept or con-
tinue turning the setting knob. The cooling symbol
flash. Press the OK-knob to accept (also refer to Fig
4.2.7 Protection mode
Use operating mode selector
refer to Fig. ).
Adjustment of standard values (frost protection = 5 °C;
overheat protection = 35 °C) being done in temperature
menu T by setpoint (refer to Operating Instructions).
5 Replacing the controller on its base
