8.7.13 Frost Protection
Frost protection will assist in keeping the NeoTherm
from freezing when the unit is not able to fire, but is still
able to run the pumps. The frost overrun time can be
changed on this screen.
8.7.14 System Configuration
The installer can set the control to display temperature
units in °F or °C, can adjust the anti short -cycle time,
the low fire cutoff time, burner off inhibit time, and can
set the time allowed for an alarm to sound before being
silenced.
8.7.15 Fan Configuration
To increase/decrease the speed at which the fan control
loop reacts to a decrease in fan speed, adjust the Fan
gain down parameter. Similarly, to increase/decrease
the speed at which the fan control loop reacts to an
increase in fan speed, adjust the Fan gain up parameter.
The minimum duty cycle is a view only parameter. To
set a fixed RPM at which the fan should ramp up or
down, adjust the Speed up ramp or Speed down ramp
respectively.
8.7.16 Sensor Configuration
The outdoor temperature can be read from the outdoor
sensor that is shipped with the NeoTherm.
