1.
Read these instructions carefully. Failure to
follow them could damage the Arzel
®
Zoning
System and/or cause a hazardous condition.
2.
Disconnect the power supply to the HVAC
system and the Zoning System before making
any wiring connections to prevent the danger of
electrical shock or equipment damage.
3.
The Arzel System is designed for indoor use
only.
4.
You must touch a grounded metal object before
handling the Control Panel to avoid potential
loss of internal programs due to electrostatic
discharge.
5.
Install in ambient temperature between 40
o
F
and 95
o
F in a non-condensing area.
6.
Be sure the HVAC manufacturer’s operating
specifications are compatible with the Arzel
Zoning System.
WHEN INSTALLING THIS PRODUCT...
CONTROL PANEL DANGER!
7. Check all sysem operations after installation is
complete.
8.
All wiring must comply with applicable electrical
codes, ordinances and regulations.
9.
Use properly grounded tools, safety glasses and
gloves, when drilling or cutting sheet-metal
ducts, fiberglass or any hard objects.
10. The damper blade gently wipes the inside of the
ductwork. Insert a sleeve inside any fiber- glass,
or abraidable ductwork, so the blade does not
abrade the materials into the air.
11. Leave these instructions with the installed
system for future use.
12. There are both AC and DC Terminals on the
circuit board. Do not intermingle wires.
13. All LAT limit controls are to be used as
secondary controls only. The LAT control
setting must be below/above your primary
factory protection level.
GENERAL SYSTEM OPERATION:
A call from any zone thermostat will call on the HVAC equipment, position the solenoid air valve and open
the dampers for its zone. Both micro pumps are energized to automatically position the dampers, either
open or closed, as required. The vacuum pump opens the dampers, and the pressure pump closes the
dampers. When the thermostat is satisfied, a 3-minute Energy Conservation Cycle™ (ECC) is initiated
and the dampers are held in place for 2 minutes. This will deliver the residual conditioned air to the last
zone(s) served. In the third minute, the micro pump continues to operate to open all the zone dampers for
a SofStart™ on the next cycle. See ECC Bypass (Fig. 9d) if you wish to eliminate the third minute of the
ECC cycle.
LOCATING AND MOUNTING THE CONTROL PANEL:
Locate the control panel on a wall area near the HVAC air-handling equipment (furnace, fan, coil, etc.)
5-feet above the floor. Do not mount the control panel on ductwork or HVAC equipment. Panels should be
installed in non-condensing areas at an ambient temperature range between 40
o
F to 150
o
F.
24-VOLT POWER SUPPLY AND GROUNDING:
One 24-Volt AC transformer (provided with the system) powers all zone thermostats, and the Arzel
Control Panel. The HVAC system transformer provides power for the heating and air-conditioning
equipment outputs only. Do not mix HVAC and Arzel transformer outputs. A positive ground terminal is
provided for grounding connection. (Fig. 5a)
