8 x Errors, malfunctions and messages
Heating does not warm
up enough
Water flow too low.
Check that all stop valves of the water circuit are
completely open.
Check that the water filter is dirty.
Check that the expansion tank is defective.
Fully vent the heating system and device-internal
circulation pump.
On the control unit (rotary switch position "Info"
)
check that there is sufficient water pressure (>0.5 bar),
if necessary, refill the heating water.
Check that the resistance in the water circuit is not too
high for the pump (see installation manual for
"Technical Data").
Target value range is too low.
Increase parameter [Heat-Slope].
Increase parameter [T vbh1 max].
Increase parameter [Max T-Flow].
Weather-controlled flow temperature regula-
tion.
Check the settings on the "HC Configuration" level of
the parameters [T-Outside lim day], [Heat-Slope] and
the settings in the "Set Temp Day"
rotary switch
position.
Optional Backup-Heater (EKBUxx) or alterna-
tive heater not switched on.
Check the mains supply to the Backup-Heater
(EKBUxx).
Thermal protection switch (STB) on Backup-Heater
(EKBUxx) has been triggered. Unlock.
Check the parameters [Function Heating] and
[BUH s1 power] and [BUH s2 power].
Water quantity in heating system too low
Check the primary pressure in the expansion
container and the water pressure, if necessary, refill
the heating water and reset the primary pressure
(see chapter 7.4).
Hot water supply is taking too much of the out-
put of the heat pump.
Check the settings of the parameter [Function
Heating] in level "Configuration", sub-level "Setup".
Check the settings of the parameter [Power DHW] in
level "Configuration", sub-level "System ".
Hot water does not warm
up
DIP switch configured incorrectly
Check DIP switch setting on board A1P
(see section 8.4).
Hot water supply switched off (e.g. switching
time program is in the economy phase,
parameters for hot water supply have been
set incorrectly).
Check the operating mode setting.
Check the request parameters.
Storage tank charging temperature too low. Increase the target hot water temperature.
Draw-off rate too high. Reduce the draw-off rate, limit throughput.
Output of heat pump too low.
Check the switching times for room heating and hot
water supply for overlaps.
Water quantity in heating system too low.
Check the primary pressure in the expansion
container and the water pressure, if necessary, refill
the heating water and reset the primary pressure
(see chapter 7.4).
Optional Backup-Heater (EKBUxx) or alterna-
tive heater not switched on.
Check the mains supply to the Backup-Heater
(EKBUxx).
Thermal protection switch (STB) on Backup-Heater
(EKBUxx) has been triggered. Unlock.
Check the parameters [Function Heating] and
[BUH s1 power] and [BUH s2 power].
