Controllability
The potentiometer-controlled speed selector allows accurate setting of airflow
The unit has 2 fully variable speeds for trickle and boost, with an inbuilt humidistat activation for the boost speed.
A switched live (LS) can also be used to select boost speed when wired through an Isolator Relay (Part No. 442030 - not supplied).
An additional third speed (purge) is available using a second switched live connection.
MVDC-MS H
(443298) the Boost setting is activated by the internal humidity sensor. The internal humidity sensor uses one of the two available LS inputs, the other remaining LS input can be used to switch the unit to Purge speed.
MVDC-MS H
has the option to switch from Normal to Boost speed (in effect over-riding the internal humidity sensor), this can be achieved by connecting an isolated switched live connection to the LS connection on the power supply terminal block. This must be isolated by using, for example an Isolator Relay Control, Vent-Axia part number 442030, or similar.
