Cooling Down; Power Outage - Wamsler WP2-8 Instructions D'installation Et D'utilisation

WP2-8_GB 61 / 189
When the boiler has been turned off, the green LED keeps flashing until it is fully switched off
(OFF).
INACTIVE STATUSES
When the P2 (ON/OFF) key is pressed to turn the appliance off, the goes to SWITCH OFF
status, and then switches over to cooling down.
The exhaust gas fan switches to the highest grade in order to burn all the pellets in the
combustion chamber.
The following status can be reached only when the temperature of the exhaust gas does not
exceed the 70°C limit value.

COOLING DOWN

The exhaust gas fan remains in switched on status for 300 seconds.
Thereafter, the exhaust gas fan fully switches off (LED L2 in OFF status).

POWER OUTAGE

In the case of any power outage not longer than 10 seconds, the boiler continues to operate.
When the boiler is in STAND-BY mode, it switches back in this mode.
In all the other statuses, the boiler switches off when there occurs power outage.
PRESSURE DROP (pneumatic storage tank)
When there is any unforeseeable pressure drop in the equipment, and the pneumatic storage
tank opens in the burning phase, then the boiler switches over to "DEPRESSION" status, where
the exhaust gas fan increases the speed until the pneumatic storage tank can close again.
When the contact element of the pneumatic storage tank remains open for more than 20
seconds, then the boiler switches over to the alarm status due to the pressure drop.
ALARM
Upon any fault indication, the boiler switches into alarm status after a 60-second delay. If the
fault indication is not cleared within the prescribed period, the boiler shifts into alarm status, and
switches off. Then, the exhaust gas fan operates at maximum speed.
The memory records all the alarm statuses in the alarm history, with the exception of the "no
pellet" status.
