warm the radiators get. Since the warmth is usually spread across several
radiators, the radiator temperature usually is distinctly below the displayed
value.
Flow Setv:
The control tries to heat the heating circuit up to that value and keep it
remaining there. Amongst others, the actual value is influenced by
dimensions such as outside temperature, requested ambient temperature,
actual ambient temperature (if room device available) etc.
NOTICE: If the mixer is set to "OFF" (heating circuit without mixer), the
upper buffer temperature is shown as the flow-setv-temperature.
Pump OFF Mixer CL
Pump = heating circuit pump OFF/ON;
Heating circuit mixer (= eletric control device to regulate the flow "warmer"
or "colder") –
CL = closes (temperature falls), STOP (temperatur reached),
OPEN = opens (temperature rises). NOTICE: If the mixer is set to "OFF" at
“Basicsettings Menu” (heating circuit without mixer), the display frame
"Mixer CL" is omitted".
Status line:
Here, the current heating circuit status is displayed; the following texts are
possible:
"Summer!"
Heating temperature switched off automatically as outside temperature is
too high and thus heating is not required any longer.
(see menu frame "H-circuit 1 temperatures").
"Hightemp.running!
Heating circuit heats to reach and keep the "high" room temperature
setting (see menu picture "H-circuit 1 Temperatures").
"LowTempMode on!
Heating circuit heats to reach and keep the "low" room temperature setting
(see menu picture "H-circuit 1 Temperatures").
"Frostprotect!"
Operational mode is set to "frost protection", heating circuit is not heating.
(temperatures have not reached the frost protection range).
"Frostpr.running !"
Heating circuit heats in "frost protection mode" to reach and keep the frost
protection temperature (8°C)
"Roomtemp. OK!"
Water is being heated, the buffer is still too cold, burner switch is set to
"ON", pellets burner starts to load the buffer.
„Lowering active!"
The set value is “low” to lower the room temperature from a “high” to a
“low” setvalue. For that, the pump is switched off and the mixer closed.
In an hourly interval, the pump is activated for a few minutes. If the
flowtemperature falls to low, the heating circuit is switched on and heats to
reach and keep the "low" temperature.
"Dom.wat1 loading"
"Dom.wat2 loading"
"Dom.wat3 loading"
If the loading of a Domestic hot water tank takes longer than 1.5 hrs, the
heating circuit is switched off temporarily to enable the Domestic hot water
loading to the set value.
"Buffer cold!"
Heating circuit would like to heat, but buffer still too cold. If the burner switch
is set to "ON", the pellets burner starts to load the buffer.
"Probe faulty!"
The heating circuit flow-probe is defective or not connected.
„Screed drying on!"
The function “Screed drying” is active see “Screed drying”.
