Screen Link Multiplexer
Part number: CSLM
Overview
The Screen Link Multiplexer is used to display and control up to four AC systems on a single Nova CAT wall controller (CCASLWE). It also supports connecting up to two Nova CAT wall controllers to a single Multiplexer. The Screen Link Multiplexer forms part of a Screen Link Multiplexer Kit (CSLMK), wich consists of a CSLM + 1m CAT5 cable (CFC1s).
Installation Guides
Each ducted AC unit is connected to a CPU Module (C225). A Screen Link Module (CSL) in turn is paired with a CPU Module. In order to show multiple ducted AC units on a Nova CAT wall controller, connect each CSL module to the CSLM. From there, run a CAT5 cable and connect the Nova CAT wall controller. All the systems will now be controllable from the Nova screen.
Each Multiplexer is powered seperately with a 24VAC power supply (CT24ACE). The Multiplexer can display up to 4 indoor units and a maximum of 2 Nova wall controllers can be connected.
