3. Scroll to Parameters 31 and 39 and set values.
•
The remote setpoint value for 10V is set using Parameter 39.
•
The remote setpoint value for voltage input between 0V and 10V is linearly distributed
between 32°F and the value set for Parameter 39.
•
The heat request is maintained until the remote setpoint falls 3.6°F below the value set
for Parameter 31, at which point the unit will go to Standby.
•
The heat request will resume when the voltage input reaches the value set for
Parameter 31.
Example:
Set Parameter 39 = 140°F
Set Parameter 31 = 90°F
10V signal will call for 140°F setpoint.
9V signal will call for 129°F setpoint.
7.5V signal will call for 113°F setpoint.
Unit will go to Standby when voltage signal drops to 5.04V (86.4°F remote setpoint).
Unit will resume operation when voltage signal reaches 5.37V (90°F).
