General mode of operation
Heating circuit regulation
Weather-based regulation
The set heating curve is used to
determine the boiler or supply
temperature appropriate to the
measured outdoor temperature,
such that with a properly
configured heating system in the
reference room, approximately the
set room target temperature value
is achieved.
=> The precise setting of the
heating curve is extremely
important for weather-based
regulation.
The circulation pump is
regulated based on the weather.
The circulation pump is switched on
when there is demand for heating
and in frost protection mode.
Room sensor influence
The current room temperature can
be factored into the calculation of
the required supply temperature by
installing a room temperature sensor.
The influence factor (parameter
list) can be set between 0
(regulation purely based on
the weather) and 20 (room
temperature-based regulation
with only a slight influence from
the outdoor temperature). In the
position “----” room temperature-
based regulation is deactivated.
The positions “----” and “0” show
differences for demand-oriented
circulation pump switching.
Water heating
The hot water programme of
the control module affects Hot
water target temperature I of the
connected main controller. The
hot water programme of the main
controller is a separate programme.
frost protection temperature, the
room target temperature for the
corresponding heating circuit is
set to 5°C. The heating circuit is
enabled:
- Pumps are switched on
- Request for heat is sent
to the boiler
“----” => Outdoor frost protection
sensor is deactivated
The function is cancelled if the
outdoor temperature climbs
above the set frost protection
temperature by 1K.
Frost protection via the room
sensor
If the room temperature drops
below 5°C, the frost protection
function is activated.
The room target temperature for
the corresponding heating circuit
is set to 5°C. The heating circuit is
enabled:
- Pumps are switched on
- Request for heat is sent to the
boiler
Condition for shutdown:
Room temperature-based regulation
The room temperature exceeds
the set target value.
Weather-based regulation
The outdoor temperature exceeds
the target room temperature value
or the target supply temperature
value by 20°C.
If the room sensor influence is
“0”, after a one-off demand
for heating during the
reduction period, the pump
runs continuously.
NOTE
When the circulation pumps are
shut down, there is a lag period
of 5 minutes, if the burner was
switched on in the last 5 minutes
before the pump shutdown.
Pump lag
The controller effectively prevents
the pumps from seizing due to
extended shutdown periods.
The integrated protection function
switches on all pumps, which have
not been run in the past 24 hours,
daily at 12:00pm for 5 seconds.
Pump seizing protection
Frost protection function
The frost protection mechanism
prevents the heating system from
freezing by automatically switching
on heating mode.
Outdoor frost protection sensor
If the measured outdoor
temperature drops below the set
Every 10 minutes, an automatic
check is performed to determine
that the settings values of the
controller are within the specified
limits. If a value is found to be
outside of the limits, then it is
replaced by the associated default
value. Error 81 appears in the
Favourites line on the standard
display to indicate that a value
exceeded the permissible range.
In this case, the user should check
the key settings of the controller.
The warning symbol goes out after
the unit is restarted (RESET).
EEPROM check
If the mixer has not moved for
24 hours, is is fully opened once
at approx. 3:00am. During this
time, the heating circuit pump is
switched off. The maximum supply
temperature is monitored. The
process is cancelled if maximum
supply temperature – 5K.
Mixer seizing protection
Heating demand-dependent
switching
Demand-dependent circulation
pump switching shuts down the
circulation pumps if there is no
demand for heating. At the same
time, the mixers are closed.
