Robertshaw SlimZone Deluxe ZONE CONTROL SYSTEM - Manual (Page 7)

• Proper location of motorized zone dampers is important. Motorized zone dampers
should be located on the trunk lines as close to the main supply plenum as possible or,
when necessary, where branch lines intersect the trunk. This will greatly minimize air
noise and reduce turbulence. Always make sure that zone dampers are accessible for
service and/or replacement.
• Plenty of return air helps provide optimum results. It is recommended that each zone
have its own return whenever possible. When this is not possible, the return air path from
one zone should not influence any other zone thermostat. Sufficient return air is required
to maintain proper zone control. Do not rely on free air infiltration for optimum results.
• Balancing dampers should be installed ahead of all motorized zone dampers.
• Whenever possible zone dampers should be installed 10 ft (3m) from discharge grilles and
registers. Flex or lined duct is recommended on the last 5 ft (1.5m) to the grilles or registers.
• Pressure drop across the motorized zone damper is negligible and normally not a factor
when sizing or calculating branch duct CFM.
• When HVAC equipment incorporates an economizer, it is recommended that the econo-
mizer be equipped with an air relief damper.
• Robertshaw motorized zone dampers are designed to work only with low pressure sys-
tems of 1.0 inches wg or less.
• Zone thermostats and motorized zone dampers may be located up to 300 ft (90m) from
the Deluxe logic panel when 18AWG copper thermostat wire is used.
• The Deluxe system requires standard electromechanical or electronic heat/cool thermo-
stats. Do not use heat pump thermostats. The control algorithm in the Deluxe logic panel
is configured such that heat pump thermostats are not required.
• Maximum load allowed to be switched by the output terminals is 2.5 amps at 60ºF
(20ºC). All outputs are protected by a current limiting device (poly-switch).
