W36, E36 Standby Modus active
Function:
Indicates that a standby operation is active (Draining, AntiFreeze
or KeepWarm).
Procedure:
–
Standby-Operation “Draining”
If a module has no demand for 72 hours standby draining is triggered on
the unit. During draining the information W36 is shown in the display. In
standby mode the draining function is triggered only once (no repetition
after 72 additional operating hours without demand).
–
Full Draining
With full draining the cylinder is completely drained (3 minutes) after
72 hours in standby operation.
–
Partial draining
With partial draining only a short draining cycle is performed. Subse-
quently, it is checked whether or not there is a current flow between
the electrodes. If still current flows (the electrodes are still in the
water), the draining is repeated (max. 20 times). If no current flows,
partial draining is terminated. If the safety chain is interrupted no
partial draining can be performed (contactor cannot be activated).
In this case a full draining is performed automatically.
–
Standby operation “KeepWarm” and “AntiFreeze”
If a module has no demand the keep warm or anti freeze function is ac-
tivated. With keep warm function the water in the cylinder is heated with
150 W for a maximum of 72 hours as standard. With anti freeze function
the water in the cylinder is heated with 50 W without time limitation.
