default
150 s for floating
This configuration variable specifies for the output 1 configured as
• FLOATING: the runtime of the valve (time to run from fully closed to
fully open)
• PWM: the cycle time
• ONE_STAGE, TWO_STAGE, and THREE_STAGE: minimum ON
time before switching to the next stage.
150 s for floating
This configuration variable specifies for the output 2 configured as
• FLOATING: the runtime of the valve (time to run from fully closed to
fully open)
• PWM: the cycle time
• ONE_STAGE, TWO_STAGE, and THREE_STAGE: minimum ON
time before switching to the next stage.
90 s
This configuration variable is used only for ONE_STAGE,
TWO_STAGE, and THREE_STAGE output 1 and specifies the mini-
mum OFF time before switching to the next stage.
90 s
This configuration variable is used only for ONE_STAGE,
TWO_STAGE, and THREE_STAGE output 2 and specifies the mini-
mum OFF time before switching to the next stage
REHEAT
This configuration variable specifies the usage of the reheat relay.
FREE_USE specifies that the relay is controlled via the network using
the nviReheatRelay .
0%
This configuration variable specifies the zero position for PWM
actuators. This setting applies to PWM actuators only and is used for
both actuators if both are configured as PWM actuators.
100%
This configuration variable specifies the fully open position for PWM
actuators. This setting applies to PWM actuators only and is used for
both actuators if both are configured as PWM actuators.
36 DDF (20 K)
This configuration variable specifies the throttling range for use in the
proportional portion of the PID loop gain for the cooling mode. The
minimum configurable value (not including 0 for disabling) is 3.6 DDF
(2 K) for PI or 2.25 DDF (1.25 K) for P control. For versions prior to
1.0.3, the minimum value is 7.2 DDF (4 K).
