9.6 Occupied / Un-occupied
A terminal strip for building automation systems (BAS)
is provided to force the system into occupied mode or
un-occupied mode (Home or away). The terminal strip
will be labeled “Occupancy Sensor”. This terminal strip
leaves the factory jumped which forces the system to
be occupied all the time. When the jumper is removed
or broken by the BAS the system will go un-occupied
unless schedules are set up in the Protostar touch
screen. For more information about schedules in the
Protostar see section 9.5 in this manual.
9.7 Optional Ultra Violet Sanitizer.
The Optional UV light, when ordered with the system
will have a toggle switch in the electrical box to turn on
/ off the UV light. (UV sanitizer must be powered down
if panel is removed to area where light is installed.
Severe eye burn could occur) The UV light mounting
bracket and plug will be located in the blower chamber.
The UV blub will ship uninstalled, in a box in the blower
chamber in order to prevent breakage.
9.8 Optional Zone Damper Output
If the system was designed to control multiple zones,
each zone will have a 3 position terminal strip for a
damper connection. Each terminal strip will be labeled
with the zone number and in smaller letters C, NO and
NC.
C = 24Vac common
NO = 24Vac when damper is to open
NC = 24Vac when damper is to close
A maximum of 4 zones can be controlled. The number
of dampers that can be used is limited by the power
consumption of each damper.
Total damper power consumption from all 4 zones
cannot exceed 40 VA. If power consumption is not
equally spread between all 4 zones keep in mind no one
zone can handle more than 16 VA.
For example the recommended damper motor the
Belimo LMB24-3-T, is rated for 2.0 VA. Using this
damper we could have 5 dampers on each zone output.
For example if there were only 3 zones one could have
two zones with 6 dampers and one zone with 8
dampers, but one could never have a zone with more
than 8 dampers. Check the output of your dampers if
not using the recommended Belimo damper, most
other brands will pull much more wattage then the
Belimo motors.
9.9 Thermostat Wiring
All thermostats for the advanced controller utilize
communicating thermostats. Communication wire is
required. Communication wire requirements are:
• Wire Gauge 18 AWG
• Wire Type stranded copper
• Wire insulation 0.009" low smoke PVC
• UL temp rating -40 to 75 deg C
• Jacket 0.0140" low smoke PVC
• 0.255" nominal O.D.
• Shielding foil, with drain wire. Drain wire
should be connected to ground lug in system.
• Capacitance 47 pF/ft nominal
• Resistance 6.9 ohms / 1000 feet
• Maximum length 500 feet.
Note: For a priority system, NEVER install the T-Stat
directly over the return air grill. Installing the T-Stat in
this position can cause erratic system operation. This is
due to the warm air at times rising out of the return
when the unit is heating water.
9.9.1 Protostar Touch Screen Thermostat Wiring
The Protostar Touch Screen Thermostat is the standard
thermostat used for zone one or the primary
thermostat in a non-zoned system. No addressing to
the Protostar is required because it’s always considered
zone 1.
The Protostar thermostat wires to a 4 position terminal
in the electrical box labeled “Touchscreen”. This
terminal strip has a second label identical to the
labeling on the Protostar thermostat. Connection is
simply connecting D on the terminal strip to D on the
Protostar, C to C, B to B and A to A.
It’s important to note the Protostar thermostat is
powered by 24 vac, always wire to the correct terminal
strip provided and labeled in the electrical box.
