PROGRAMMING THE RESISTIVE
MONITOR
The resistive monitor is a 0-10 kΩ analog output for monitoring the HOA switch
position. Please use the following ranges for the DDC scaling.
Condition Range* (Ω) Nominal Values without Wire
Resistance* (Ω)
Line Open Greater than 8630 n/a
HOA Off 5290 to 8630 6190
HOA Auto 2880 to 5289 3391
HOA On 1200 to 2879 1406
Line Shorted Less than 1200 n/a
* Ranges based on the presence of 0-1000 Ω of resistance due to wire. Average # of feet for 1000Ω
by wire AWG listed below.
