INSTALLATION
INSTALL THE HEAT/COOL DUCT SWITCH
OPERATION
The Climate Wizard CW-6S is available as a Stand Alone
cooling solution or as a Dual System heating and cooling
package (CW-6S Dual System) when combined with a Braemar
Ducted Gas heater. If installing a Dual System, the Heat Cool
Duct Switch (HCDS) is required to allow the cooler and heater
to share the same set of ducts and room outlets.
The Heat/Cool Duct Switch (HCDS) interacts with the
MagIQtouch Wall Control, the CW-6S Cooler and the Ducted
Gas Heater ducting dampers in the Dual System. The HCDS
automatically responds to switch the appliance ducting dampers
open and closed according to the Wall Control setting. If
Heating is selected, the dampers isolate the Cooler from the
duct outlets. If Cooling is selected, the dampers isolate the
Heater from the duct outlets.
The HCDS can be fitted to any installation using MagIQtouch
controls. It has a programmable period that delays the start of
the fan motor to allow time for the 24VAC dampers to open and/
or for residual heat to dissipate from the ducting.

The Heat/Cool Duct Switch KIT contains;
Control Enclosure Assembly (inc. Power Cable/Plug), 20m
Communication lead, Screws Enclosure Mount, Cable Ties.
NOTE: Dampers & damper control cables (24VAC) are not
supplied. Use ONLY Belimo LM24A; LM24A-T; or LM24A-90-T
damper models.
STEP 1 - ASSEMBLE THE HEAT/COOL SWITCH
ENCLOSURE
Open the enclosure and take note of output positions on the
circuit board for 24V damper wiring (not supplied).
ILL2991-A
STEP 2 - WIRING CONNECTION
Wire as per schematic diagram.
Mount a mains power supply socket in close proximity to the
heater in the roof space as the damper control enclosure
requires its own separate 240V/50Hz supply.
IMPORTANT! Do not connect until installation is complete.
Wall Controller cable (20m) must plug into enclosure marked
"HEATER". The 20m Cooler communication cable must plug
into the enclosure marked "COOLER". Both cables are routed
through the Communication In/Out cable gland.
Connect damper control cable (not supplied) to the output
24VAC on the circuit board. Ensure the damper cable is
restrained using the cable tie provided, then route through the
Damper Out cable gland.
Use the supplied screws to attach the damper control inside the
roof space either onto the dropper, on a nearby joist or near the
heater unit The Heat Cool Duct Switch must be within 20m of
the heater unit, but not on top of the unit.
Plug in the Heat/Cool Duct Switch power cable.
