ION SYST0101CW Installation Instructions Manual page 11

"Daisy chain" wiring, where each communicating component is wired one after another, rather
than all components connecting a in "star" fashion to one point, is preferred. For wiring runs
over 100 feet, terminating with a 100 ohm resistor at each end of the chain can help to avoid or
mitigate electrical noise problems.
4.4.2. Damper Control Module (zoning systems only)
When used, all wiring is run back to the Ion System Damper Control Module (SYST0101ZP).
Select a location near the furnace or fan coil where wiring from the control, each Remote Room
Sensor or Smart (Zone) Sensor (when available), each damper actuator, and the equipment itself
can come together easily. The Damper Control Module is approved for indoor use only and
should never be installed with any of its components exposed to the elements. The Damper
Control Module (and zone dampers) may be installed in any area where the temperature remains
between -4°F to 158°F (-20°C to 70°C), and there is no condensation. The cover must be
installed to prevent damage from other sources. Do not locate where it will be accessible to
children. It may be mounted in either vertical or horizontal position. Remember that wiring
access is likely the most important consideration.
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
To prevent possible damage to the Damper Control Module, DO NOT mount on
plenum, ductwork, or flush against furnace or fan coil.
4.5. Decorative Trim Plate
Sold separately, a thin decorative trim plate is available to hide any marks/screw holes left from
the previous thermostat. The trim plate is captured between the backplate and the system
control. Align the trim plate around the backplate, and snap on the system control.
4.5.1. Mounting
First become familiar with all plastic assembly pieces shown on the following page. The Ion
System Control will snap together with the standard backplate supplied with the wall control.
Attach backplate using only a small hole in the wall allowing a four wire connection to pass
through. Mount the front assembly to the standard backplate. The figure below shows the
optional decorative trim plate, described in the Decorative Trim Plate Section, installed with the
standard backplate. The decorative trim plate is captured between the backplate and the system
control. Align the decorative trim plate around the backplate, and snap on the system control.
