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

4.2 INSTALLATION OF BACKPLATE
The control panel can be mounted on any interior surface. Use the mounting holes (Figure
4.1) to secure in place using the supplied #8 screws. Mount the control panel in a location
that provides easy access for service. Do not mount the control panel on any part of the
HVAC equipment or where moisture may be present. Also, it is strongly recommended that
the panel be installed on a nonvibrating surface. There are several round holes and knock-
outs for through-the-wall or surface wiring.
CAUTION:
Use proper care when removing upper or lower end cap knock-outs. Apply a sharp rap with
the butt end of a screwdriver to remove knock-outs. Do not use sharp instruments to
remove the knock-outs as internal damage may occur.

4.3 THERMOSTAT INSTALLATION
Heat pump thermostats must not be used with the SlimZone Classic panel. Zone
thermostats should be installed in a location that best suits the general load characteristics
of the space it will control. Do not mount thermostats in hallways, exterior walls, or near
cold air returns or registers.
4.4 WIRING
Use #18 AWG (nonshielded) copper wire for all system wiring. Thermostats and damper
actuators may be located up to 300ft. (90m) from the control panel. All system wires
should be tagged to identify thermostat, damper, and equipment wiring. Refer to Figure
4.2 for panel wiring diagram. A spare or third wire should be run between the control panel
and each zone damper in the event that a 3 wire damper actuator is used.
4.5 DAMPERS
Typical dampers are designed to work with low pressure systems (1.0" WC or less).
Balancing dampers should be installed ahead of all zone dampers. Zone dampers should
