INSTALLATION
ZONE DAMPERS
1. Zone dampers may be two-wire (powered closed, spring open) or three-wire (powered closed, powered open)
2. Two-wire dampers connect to the zone damper terminals marked ‘D’ and ‘D’. Three-wire dampers connect to
the terminals marked PC (Powered Closed), C (Common), and PO (Powered Open).
3. As many as three dampers may be wired in parallel for any single zone, providing the total VA of all dampers
does not exceed the VA rating of the zone control panel transformer.
4. A 40 VA transformer will power the panel and up to four (4) dampers. A 75 VA transformer will power the panel
and up to seven (7) dampers.
5. If the total VA of all dampers exceeds 75 VA, a relay and a separate 24 volt transformer will be required to
power additional dampers.
6. Use only 18 gauge thermostat wire. Do not exceed 300 feet from zone damper to control panel.
ZONE THERMOSTATS
1. Zone thermostats must match equipment type. (Heat / Cool or Heat Pump) Power stealing thermostats are not
recommended.
2. Use only 18 gauge thermostat wire. Do not exceed 300 feet from zone thermostat to control panel.
REMOTE SENSORS
Z-600-DAS
1. Mount the Z-600-DAS Discharge Air Sensor in the supply trunk. Mount the sensor out of the line of sight of the
heat exchanger and cooling coils whenever possible and before any zone dampers. The Z-600-DAS sensor
has a resistance value of 10,000 Ohms @ 77° F.
2. Use 18 gauge thermostat wire to connect the sensor to the DAS terminals on the zone control panel.
Z-600-OTS
(For dual fuel applications)
1. Mount the Z-600-OTS Outdoor Temperature Sensor inside the outdoor unit where it will not be directly exposed
to sunlight, water, snow or ice. The Z-600-OTS sensor has a resistance value of 10,000 Ohms @ 77° F.
2. Use 18 gauge thermostat wire to connect the sensor to the OTS terminals on the control panel.
HVAC UNIT
1. Wire the HVAC unit to the HVAC System terminals on the zone control panel. For equipment having separate
heating and cooling transformers, cut the jumper marked RH-RC on the control board and wire independently.
2. Use 18 gauge thermostat wire to connect the zone control panel HVAC System terminals to the HVAC
unit
terminals.
3.
The 24 VAC equipment common does not wire to the Z-600 panel
.
