7 Appendix 1- Options
7.1 General
ML180-MLT350 dehumidifiers have been designed to ensure that
options can be incorporated with the minimum external physical
alteration.
For connections details refer to the Circuit Diagram Supplement provided
with the unit.
NOTE! Voltage drops may be experienced when using excessively long cables. At
operation the voltage must be 24V measured at the connection point
(dehumidifier) for ALL external humidistat and remote switch connections. If the
measured voltage is less than 20V, a separate relay controlled by the humidistat
must be used.
7.2 Configuration alternatives
This appendix includes information about all configurations and
components that can be added when ordering ML dehumidifiers.
7.3 Running Time meter
The running time meter indicates accumulated number of hours the
dehumidifier has been in dehumidifying operation. The two digits to
the right indicated percentage of one hour, e.g. 0000475 should be
read as four hours and 45 minutes. The running time meter is not
re-setable.

7.4.1 General
Checking and changing set points and control parameters can be made
