Commissioning
Preparatory checks
1. Do NOT turn on power yet.
2. Check wiring to ensure it accords with the plant's
connection diagram.
3. Check each actuating device to see if ...
– it is correctly installed (observe direction of
flow indicated on valve body),
– manual control is disengaged.
4. Exercise caution in connection with floor and
ceiling heating systems!
The limit thermostat must be correctly set. During
the function check, the flow temperature must not
exceed the maximum permissible level (usually
55 °C); if it does, proceed immediately as follows:
– Either close the valve manually, or
– Switch off the pump, or
– Shut the pump isolating valve .
5. Turn on power. The display shows the time of day.
If not, the reason may be one of the following:
– No mains voltage
– Main fuse defective
– Main switch not set to ON
6. Addressing the room units:
– Room unit heating circuit 1 = address 1
(factory setting)
– Room unit heating circuit 2 = address 2
General information about operation
• Setting elements for commissioning:
– Readjustment of room temperature: Via setting knob,
separately for heating circuits 1 and 2!
– Other variables: On the display; each setting is
assigned an operating line. If required, make
separate settings for heating circuits 1 and 2!
• Buttons for selection and adjustment of values:
Press to select the next lower operating line
Press to select the next higher operating line
Press to decrease the displayed value
Press to increase the displayed value

• Block jump function:
To select an individual operating line quickly,
2 button combinations can be used:

• When pressing one of the buttons, the display lighting
is switched on for a certain time
Setting procedure
1. Make the required settings on the "End-user" level
(operating lines 1...50).
2. Configure plant type on operating line 51.
3. Enter the relevant settings on the parameter list
below. All functions and operating lines required for
the configured plant type are activated and adjust-
able; all operating lines that are not required cannot
be accessed.
4. Make the required settings on the "Heating engineer"
level (operating lines 61...208).
Commissioning and function check
• Operating lines especially for the function check:
161 = simulation of outside temperature
162 = relay test
163 = sensor test
164 = display of setpoint
• If Er (error) appears on the display: Query operating
line 50 to pinpoint the fault
• If no operating line is selected for 30 minutes, or if
one of the operating mode buttons is pressed, the
controller switches to the "non-operated" state
