1.1.7Configuring the cleaning trigger 1 (Clean Trg. 1)

With the cleaning trigger 1 settings you determine whether the forced draining/cleaning (MHTC Reflow) or the box cleaning (MHTC Flow) is time or interval controlled or triggered via an external signal. The forced draining can be deactivated, however the box cleaning can be deactivated. The forced draining cannot be deactivated for the MHTC Reflow. The washing can be deactivated for either the MHTC Flow or Reflow.

Note: the forced cleaning/draining serves to empty the water tub regularly and independent of the operation time of the Nortec MH.

Select “Clean Trg. 1” in the settings menu, then press the <Set> key. The current settings for the forced draining/box cleaning appear. The available settings depend on whether the interval controlled (Periodic (factory setting), timer controlled (Timer) or external signal controlled (Demand) triggering of the forced draining/box cleaning is selected.

Interval controlled draining/box cleaning (Periodic). With Periodic Int you can determine in which time intervals the draining/box cleaning is performed (setting range: 0.5 ...24 .0h, factory setting: 2.0h).

Time controlled draining/box cleaning (Timer)With the parameters “time 1” to “time 4” you can define up to four times of day to start the draining/box cleaning (factory setting: no starting times defined).

Triggering the draining/box cleaning via an external signal (Demand). In order to trigger the draining/box cleaning via an external signal

apotential-free contact (B4 ) must be connected to the control board of the control unit MH. Closing the contact results in a draining/box cleaning cycle.

Cleaning trigger 1 deactivated (Off)Note: this option is only available/visible for model MHTC Flow.
