Ç Operating mode selection
Turn the knob to select the operating mode required. The
operating mode selected is indicated by a symbol at the
bottom of the display. It takes effect when the setting is not
changed for 5 s.
The following operating modes are available for selection:
i

Part 1: Operation
Operation in normal mode
W
Service (automatic reset after 15 min)
heat generator regulates to HS set temperature =
maximum HS temperature => as soon as a HS
temperature of 65°C is reached, the consumers regulate to
their maximum flow temperature for heat removal (cooling
function).
!
The cooling function must be explicitly enabled in
the consumer circuits by means of a set value.
Effect of the operating mode
The operating mode set here affects the boiler regulation
and the integrated heating circuits of the controller.
Each heating circuit can be assigned a separate operating
mode from the one set by means of the "operating mode"
parameter in the user level of the corresponding heating
circuit.
When the "i = Standby/OFF", and "F = Summer mode"
operating modes are set, they have a reducing effect on
system controllers with respect to all heating circuits and
consumer circuits in the entire system.
!
For mixer controllers the reduction of operating
mode is only effective for internal heating circuits.

temperature displays. Temperatures which change
rapidly can have higher deviations for short periods
due to the different time-related behaviour of various
sensors.

Duration of lowering phase at least 6 hours
At the beginning of the lowering period, the current room

The heating curve is calculated from the values
determined during this time by the regulator for the flow
pipe nominal temperature and the external temperature.

heating circuit (see FBR).
[Plug III; 1+2]
The flow temperature control operates like normal room
control [ROOMS-INFL].
The set value for the water temperature can be entered in
the user area of the associated heating circuit level
[T-POOL1/2/3]. The heating program operates. No heating
takes place during the reduction period (frost protection
only).
The water temperature and the current set value are
displayed in the display level [T-POOL / T-POOL DES].

This function can be used to operate additional hot water
circuits. The heating circuit flow sensor is located in the hot
water storage tank.
The hot water temperature set value can be entered in the
user area of the associated heating circuit level [T-DHW

04 => Return flow temperature increase via mixer motor
(only for HC2)
The heating circuit flow sensor is used as a heat generator
return flow sensor. The mixer motor controls to the heating
circuit set value for 24 hours [MIN T-FLOW].
Installation tip: Mixer motor OPEN => boiler flow is fed
into the return (=> return flow temperature increase)
Mixer motor CLOSED => heating circuit return is passed
through. When the mixer motor is open it must be ensured
that there is circulation through the HS (boiler pump).
05 => Header pump
(only for HC1)
The pump relay for the direct circuit is used as the header
pump for the cascade. The pump switches ON as soon as
heat is requested from the cascade. The pump switches
OFF when there is no longer a heat request and the followup time has elapsed.
PUMP MODE (pump operating mode)
The circulation pumps are switched off if heating is not
required. The mixer motors are closed at the same time =>
"The heating circuit is switched off".
(Switch on with 1K hysteresis)
This adjustment concerns the weather dependent shutdown. If room temperature regulation is enabled (ROOMSINFL > 0) the "thermostat function" takes effect in addition.

The measured temperature setting for the heating circuit
flow is limited to the maximum flow temperature setting
(overheating protection).
MIN T-FLOW (min. flow temperature)
The measured temperature setting of the heating circuit
flow is increased to the minimum flow temperature setting
(e.g. with air heating).
T-FROST PROT (frost protection temperature)
If the outside temperature drops below the programmed
value, the system switches to frost protection mode
(pumps are switched on).
"----" Frost protection mode is deactivated!
OUT-TEMP-DEL (outside temperature delay)
The selected outside temperature delay must be matched
to the type of construction of the building. In the case of
heavy structures (thick walls), a long delay must be
selected since a change in outside temperature affects the
room temperature later accordingly. With light structures
Expert area
Part 3: General function description
(walls have no storage effect) the delay should be set
(0 hrs.).
SLOPE OFFSET (heating slope distance)
The HS temperature that is required for a mixer circuit is
calculated by adding the calculated temperature setting for
the heating circuit flow to the heating curve distance. The
heating curve distance compensates for sensor tolerances
and heat loss up to the mixer.
B-HEAT SINK (circuit enable)

01 => The heating circuit can be used by higher-order
functions (e.g. cooling function of a heat generator to

Heat circuit control
Weather-dependent control
The HS or flow temperature is determined via the set heat
slope to suit the measured outside temperature in such a
way that the set value for the room is approximately set if
the heating system is configured correctly.
=> Exact setting of the heat slope is extremely important
for weather-dependent control.
The circulation pump is controlled weather-dependently.
The circulation pump is switched on if there is a heating
demand and in Frost-protection mode.
Room sensor influence
The current room temperature can be included in
computation of the required flow temperature via a present
room temperature sensor.
The influence factor (parameter list) can be set between 0
(fully weather-dependent regulation) and 20 (room
temperature regulation with minimal outdoor temperature
influence). Position "----" deactivates room temperature
control. Positions "----" and "0" indicate differences for
demand-dependent circulation pump control.

Hot water generation
The programmed hot water temperature is stabilised by
switching the hot-water cylinder charging pump and the
burner. Storage tank charging starts when the storage tank
temperature drops below the temperature setting by 5K.
Storage tank charging stops when the temperature setting
is reached.
Frost protection function
The frost protection circuit prevents the heating system
from freezing by automatically switching heating operation
on.
Outdoor sensor frost protection
If the measured outside temperature drops below the set
frost protection temperature the room temperature setting
is set to 5°C for the relevant heating circuit. The heating
circuit is enabled:
•
•
the pumps are switched on
the heat request is sent to the HS

Flow or storage tank sensor frost protection
The sensor frost protection is activated when the flow or
storage tank temperature drops below 7°C. Only the
relevant pump is switched on.
The sensor frost protection is deactivated when the flow or
storage tank temperature increases to above 9°C.

temperature drops below the set heating limit by 1K
(= 1°C).
Circulation pump control
T-LIMIT DAY => applies during heating times
T-LIMIT N => applies during reduction times
Switched according to heating requirement
Demand-dependent circulation pump control (automatic
summertime switchover) switches the circulation pumps off
if there is no heating demand. The mixers are closed at the
same time.
Conditions for switch-off:
Room temperature-dependent control
The room temperature exceeds the set desired
temperature.
Weather-dependent control
Outside temperature exceeds room temperature set value
or flow temperature set value drops below 20°C.
!
If the room temperature factor is "0", the pump
continues to run during the reduced operation period
after a one-off heating demand.
Switched according to heating limits
If the outside temperature that is measured and calculated
by the controller exceeds the heating limit specified here,
heating is disabled, the pumps switch off and the mixers
Delayed pump switch-off
In the case of switch-off of the circulation pumps, the
circulation pumps are not switched off until 5 minutes later
if one of the burners was on during the last 5 minutes
before the switch-off instant.
Pump blocking protection
The controller effectively prevents blocking of the pumps if
they are not switched on for long periods. The integrated
protection function switches on all pumps which have not
been in operation during the past 24 hours for 5 seconds
at 12.00 h ours every day.
Mixer motor blocking protection
If the mixer motor has not moved for 24 hours it is fully
opened at approximately 03:00 hrs. (once only). The
heating circuit pump is switched off during this time. The
maximum flow temperature is monitored. Cancelled at
maximum flow temperature – 5K.

of the controller is reconfigured in accordance with
the connected sensors the next time the controller is
switched on.
Removing the controller:
E
Disconnect the unit from the power supply before
removing it.
d) Insert a sharp-pointed tool at an angle with respect to
the exterior wall into one of the unlocking holes (the
tool must be slid between mounting clamp and control
panel wall).
e) Lever the tool with respect to the unit exterior wall.
This causes the mounting clamp to release the control
panel wall.
Raise the unit slightly at the corresponding side and repeat
the procedure on the other side of the unit.
The unit can now be removed.
Connecting instructions
E The controller is designed for an operating current of
230 V AC at 50 Hz. The burner contact is potential-free
and must always be connected in series with the
mechanical heat generator thermostat (if present).
E Important: Bus lines and sensor lines must be laid
separately, away from mains cables!
!
Note for installation in connection with digital room
device
When installing a digital room device, the heating circuitspecific set values are adjusted at the room device. These
values are automatically superceeded inside the controller.
!
If during operation the digital room device is
separated from the BUS for a longer time period
(>5min), the heating controller will continue to work
with its own set values.
In order to avoid damages in case of errors - for deviations
from relevant set values (such as maximum flow
temperature for floor heaters) - we suggest the following
procedure:
1. Installing the new heating controller
2. Set all values for heating controller
3. Install one digital room device
4. Set all values for digital room device
After connecting or modifying the connections of
sensors and remote controls the controller must be
briefly switched off (mains switch/fuse). The function

All sensors can be checked in the "General/Service/Sensor
test" level. All the sensors that are connected must appear
in this level with plausible measurements.
Actuators (mixer motors, pumps):
All actuators can be checked in the "General/Service/Relay
test" level. All relays can be individually switched using this
level. This makes it easy to check whether these
components have been correctly connected (e.g. mixer
motor direction of rotation).
BUS connection:
In control devices with connection to
Mixer motor => Communication symbol appears in
standard display (" " or "v" depending on version)
Boiler controller => Outside temperature and boiler
temperature display (see "Display/Installation")
In boiler controller with connection to
Control unit => Room temperature displayed and current
room temperature setting blanked out "----" (see
"Display/heating circuit")
In mixer motor expansion controllers with connection to
Boiler controller => Outside temperature and HS
temperature display (see "Display/Installation")

Part 4: Installation and Start-up
Control unit => Room temperature displayed and current
room temperature setting blanked out "----" (see
"Display/heating circuit")
In case of communication problems
Check connecting cables: Bus lines and sensor lines must
be laid separately, away from mains cables! Poles
switches?
Check bus feed: There must be at least 8V DC between
the "+" and "-" terminals of the BUS connector (connector
IX, terminals 3+4). If you measure a lower voltage, an
external power supply must be installed.
Pumps do not switch off
Check manual / automatic switch => Automatic
Pumps do not switch on
Check operating mode => Standard F (test B)
Check time and heating program => Heating time
Check pump switching => Type of pump switching
Standard => Outside temperature >
