Arzel Series - AirBoss

Zoning System
Zoning Glossary
Air Pump: The Arzel
®
Zoning System uses
self-contained, low-pressure micro pumps to open
and close dampers. They provide noiseless, long-life
and economical service.
P. 12
Automatic Bypass Control: Pressure-switch
operated bypass control is available. (Must be
ordered separately.)
P. 16
Compressor Lockout “ Timed Off Delay”: When the
compressor is turned off, it cannot restart for 4
minutes. This feature allows the refrigerant pressure
to balance before restarting.
P. 9
Damper Positioning Delay: On a call for Heat, the
damper closure will delay for 1 minute to allow the air
handler to start before any dampers are positioned.
This provides for a SofStart™
.
Damper Position Indicator: External indicator of the
damper position. Makes troubleshooting and system
check-out easy.
P. 15
Emergency Heat: A changeover switch (manual or
remote) is located on the PC board for heat pump
operation only.
P. 7
Energy Conservation Cycle (ECC
™
): Dampers remain
open for 2 minutes, in the last zone that called for
heating or cooling, to take advantage of additional
energy savings from residual heating and cooling in
the HVAC system.
P. 9
EzySlide
™
Damper Installation: Round and
rectangular dampers are available from 4” to 40”.
P. 13
Fan-On-Heat: In the “ON” position, the fan starts
immediately with any call for heating at the HVAC
Output terminals.
P. 9
Fossil Fuel Back-up Switch: Switches customize the
system operation for a Fossil Fuel backup furnace
when used with a heat pump. This eliminates the
need for a fossil fuel kit.
P. 8
Heat Pump: All AirBoss™ systems are fully heat
pump compatible.
P. 7, 8
Leaving Air Temperature Control (LAT): Easily set
with rotary switches; range is 40°F to 56°F for cooling,
and 110°F to 180°F for heating. LAT sensor kit with
15-ft. cable is included.
P. 10,11
Manual Pump Switch (MPS
™
): Opens all dampers
during emergency or test operations by switching
“MPS” to “ON” and “PWR” switch to “OFF”.
P. 12
Master Zone Control (MZC
™
): Can be set-up either by
a programmable thermostat, manual switch or a time
clock. It gives control of the entire HVAC system to the
Zone 1 thermostat. Use for occupied/unoccupied
set-back, or set-up programs.
P. 10
Self-Testing LAT Circuit: LAT control will indicate, with
LED flashes, when the sensor is shorted or open.
P
.
10
Sensor Verification: Easy conversion of LAT (DC
Voltage) reading to monitor temperatures in the supply
duct.
P. 11
Smart Slave Zones (SSZ
™
): A Smart Slave Zone
thermostat controls dampers only. It does not control
the HVAC equipment, and only opens its dampers when
the conditioned air in the ducts matches its
requirements. Any number of thermostats
(programmable/ non-programmable or autochangeover)
can be used.
P. 11
Thermostat Selection: Any standard thermostat,
programmable/non-programmable or auto-changeover
over can be used. Heat pump thermostats are required
on all zones for heat pump installation.
P. 5
ThreeWay Priority
™
System: Provides a selection of
“Heating”, “Cooling” or “Automatic” Priority Systems. In
Automatic mode, the first call establishes priority.
Heating and Cooling calls always override fan-only
operation. Under any priority, an opposing call, after
waiting 20 minutes, will take control of the system
and serve its zone for up to 20 minutes. All zone
thermostats have equal, full-function heating, cooling,
and fan capability.
P. 8
Transformer: A single 24 Volt AC Transformer (40 or
100 VA) is included to power all Arzel equipment,
dampers and thermostats.
P. 4
Two-Stage: Heating and/or cooling is available from all
zones with either 2-stage or single-stage thermostats.
Second-stage time delay can be adjusted from 2 to 30
minutes if a single-stage thermo stat is used.
Second-stage (both heating and cooling) is delayed by
30 seconds to prevent starting both stages
simultaneously.
