RED-4 Wiring Instructions - Duro Dyne

Wiring Instructions
All wiring should be done in accordance with local and
national codes. Use color-coded, multi-conductor thermostat
wire.
THESE PANELS ARE DESIGNED FOR USE
WITH 24VAC CONTROLS AND SHOULD
NOT BE USED WITH OTHER VOLTAGES. USE
CAUTION TO AVOID ELECTRIC SHOCK OR
DAMAGE TO EQUIPMENT.
Wiring Supply Air Sensor
To install the optional Supply Air Sensor, connect two wires
to the Supply Air Sensor and to the two terminals marked
“SAS” on the panel.
A heat pump thermostat can be used in Zone1 to provide
emergency heat control from the thermostat. Be sure to set
DIP switch #4 to HP.
The Supply Air Sensor should be installed in the Supply Air
Plenum so that it measures the supply air temperature.
Wiring Outdoor Air Temperature Sensor
To install the optional Outdoor Air Temperature Sensor,
connect two wires to the Outdoor Air Sensor and to the
two terminals marked “OAS” on the panel.
The Outdoor Air Temperature Sensor should be installed
outside and in a shaded location.
Wiring Dampers
The panel can be used with any 24VAC power open/power
close or spring return damper. Terminal M1 is 24VAC
common, M2 is 24VAC, M4 is 24VAC when the panel
opens the damper and M6 is 24VAC when the panel closes
the damper.
Wiring Zone Thermostats
All zones can use low cost, heat-cool thermostats as shown
below. Be sure to set DIP switch #4 to HC if a heat- cool
thermostat is used in Zone1.

The panel can be used with a wide variety of HVAC systems.
Some of the more common configurations follow:
PLEASE NOTE: The RED4 panel must
be powered by an independent low
voltage power supply and not by the
