Setup Variable Function Notes
AV24 PWM minimum value or Binary On Delay
or Actuator Runtime (Tri-State Valves) Depends on OP1 configuration
AV25 PWM maximum value Depends on OP1 configuration
AV26 PWM minimum value or Binary On Delay Depends on OP2 configuration
AV27 PWM maximum value Depends on OP2 configuration
AV28 PWM minimum value or Binary On Delay Depends on OP3 configuration
AV29 PWM maximum value or Time
Proportioned Heating Controller Limit Depends on OP1-3 configuration
Sequence of Operation
The selected heating outputs will be operated according to their type and the controller stage that they
are associated with. There can be up to three stages of heating, depending on the heating type and
configuration of the outputs. Also, Outputs 1 to 3 may be defined as Time Proportioned instead.

Sequence of Operation
Input 3 represents the built-in humidity sensor and becomes the input to the internal controller. The
adjustable room setpoint (AV6) becomes the humidity setpoint. And the controller proportional band is
used for humidity control, now in units of percent. Output 1 (via AV1) will operate according to its
selected output type and the value of the controller output, typically turning O
N
when the humidity is
low and O
FF
when the setpoint value has been reached.
