VAV adjustment and diagnostic tool for use with the NMV-D3-MP.MHS or LMV-D3-MP.MHS compact volume controllers


Product Information

The MHS version of the ZTH-EU has additional functions which allow full on-site calibration and setting of the V-Nominal airflow. These additional functions only work with the MHS range of volume controllers.

The ZTH-EU.MHS comes complete with a connection lead that allows quick connection to either the NMV-D3-MP.MHS or the LMV-D3-MP.MHS compact volume controllers. 

Alternative connection leads are available to purchase so that the ZTH-EU.MHS can be used with any number of previous VAV actuator models. Please click on this link to the ZK Cables datasheet to establish if you need an alternative lead.
