HEAT ORDER
The Stages of heat will always operate in this order, with duct heat always wired as stages 1, 2, or 3.
Perimeter/Baseboard heat is always be wired AFTER duct heat stages. If there is no duct heat, wire
perimeter heat on stages 1, 2, or 3 instead.
For example, if there are 3 stages of heat, with 2 stages of duct heat and 1 stage of perimeter heat, wire
duct heat on DO-09 and DO-10, and wire perimeter heat on DO-11.
Priority order can be determined from the heatConfig (A4) setpoint.
If duct heat has priority with this example, DO-09 and DO-10 will be enabled before DO-11. If Perimeter heat
has priority, DO-11 will be enabled before DO-09 and DO-10.
• DO-09 = 1
st
stage of Heat (if tri-state is configured, the first stage is DO-10 and DO-11)
• DO-10 = 2
nd
stage of Heat (not available Tri-State is selected for 1
st
stage)
• DO-11 = 3
rd
stage of Heat (if tri-State is 1
st
stage, and a digital 2
nd
stage is needed, set heatConfig
(A4) to 3 stages of heat)
• DO-12 reserved for On/Off control for fan only.
• AO-14 = 1
st
stage of Heat
• AO-15 = 2
nd
stage of Heat (not available if a variable fan is configured)
DIGITAL HARDWARE OUTPUT CONFIGURATION
Each stage of heat requires the hardware output to be configured. The default setting for the heating
outputs is digital on/off control on DO-09, DO-10, DO-11. DO-12 is reserved for fan control only.
DO-09 can be set with stg1OutType (A1) setpoint for:
• 0 = Digital on/off
• 1 = 0-10V
• 2 = 2-10V
• 3 = Tri-State
• 4 = Custom AO14 range
DO-10 can be set with stg2OutType (A2) setpoint for:
• 0 = Digital on/off
• 1 = 0-10v
• 2 = 2-10v
• 4 = Custom AO15 range
DO-11 is set for:
• Digital on/off
DO-12 is set for:
• Digital on/off
