1.1.7 Configuring 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

a potential-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.
