Alarm Levels And Handling - Weider BWP 270 0A Mode D'emploi Et D'installation

used to improve acoustic comfort or to avoid acoustic interferences without a significant loss of performance.
(Installation not ducted on ambient air).
If your air outlet and/or air inlet are ducted, it is mandatory to set the "FanOper" parameter value to "High".
The menu parameter "FanCon" controls the fan-operating mode for the use with constant ventilation. If this parameter
is unselected ("Off") the fan will stop together with the HP. If this parameter is set to "Low" for low or "High" for high
speed, the fan will operate permanently and accordingly, while the HP is in the "standby" operating mode (= constant
ventilation). Factory setting "OFF".
Note: The design of an integrated constant ventilation system has to be done under the responsibility of an expert
specified in order to match air flows. The manufacturer declines all responsibility on such a design.
The "FanPause" function improves the operation of the DHW HP in humid environment (bathroom, laundry,
basement...). This function forces the draining of condensation water recovery box, in order to prevent overflow. When
activated the fan will stop either for 15 or 30 seconds per full operating hour. An interruption of the HP fan operation
(e.g. because the water temperature set point has been reached) resets the "FanPause" function timer. The timer restarts
together with the HP operation. If "FanCon" is activated, the "FanPause" function will interrupt the fan operation after
every full operation hour. If "FanPause" is set to "Off" then the function is deactivated.

ALARM LEVELS AND HANDLING

There are 3 alarm levels. The display can show 3 different alarms at the same time. The alarm must be acknowledged and
reset by pressing the rotary/push button.
Level 1 - The information alarm: does not affect the HP operating, but informs the user that there is a problem, which
might need action and should be resolved as soon as possible. (Alarm no. 8, 9 and 10).
Level 2 - The cooling circuit alarm:: This alarm level stops the DHW production via HP. If a supplementary heating is
chosen in the "Heatpump" parameter menu ("HP + FL", "HP+boil", "EL", or "boil"), DHW is generated by the
supplementary heating up to the DHW "SETPOINT" temperature. (Alarm no. 3, 4, 5 and 6).
Level 3 - DHW HP alarm: The DHW production will cease completely. A severe malfunction or defect is supposed. This
alarm level needs the intervention of your installer or the manufacturer's after-sales-service. (Alarm no. 1 and 2)
The user can see the alarms in the alarm menu, where also the alarms are acknowledged. The problem/defect has to be
settled and the alarm has to be acknowledged, before normal operation resumes. If there are simultaneous alarms, the
alarms are displayed (up to 3 alarms) in a sequence, according to their priority.
Special handling of Pressostat switch alarms (alarm 5 & 6)
The Pressostat switch protects the compressor and the cooling circuit against overpressure. At the first time the problem
comes up, alarm nr.5 is displayed and the HP stops operating. LED (29) is flashing in red until the problem is solved
(pressure is normal again), The now resumes normal operating mode automatically. (LED indicator: standby mode =
orange light; HP operating mode = green light). If alarm 5 persists, call your installer.
Should a Pressostat problem occur again in less than 6 hours after the first alarm, alarm nr.6 is displayed and the HP
stops operating. Call your installer! LED (29) is flashing in red until the problem is solved (pressure is normal again) and
the alarm acknowledged by pressing the rotary/push button, The LED (29) now flashes in orange. When the alarm is
reset, the HP will restart and LED (29) turns for constant light (standby mode = orange light; HP operating mode = green
light).
