Vent-Wise Screens

These screens are only displayed if a Vent-Wise Card is fitted. Replacing J4 3-4 link with a Vent-Wise board
converts S/W1, S/W2 and S/W3 from switch inputs to Vent-Wise inputs. In addition SW4 can be used by a
momentary switch.

Vent-Wise sensors measure current or temperature. When the current or temperature exceeds a ‘trip’ level,
boost airflow is selected. Low / Normal airflow is resumed after a timed delay once the current or temperature
has dropped below the trip level.

Any of the sensor types can be connected to S/W1, S/W2 or S/W3 but once the Vent-Wise Card is fitted,
ordinary switches must not be used.

In use, the Vent-Wise Card with three sensors will run hot to the touch albeit well below its maximum
temperature. If any input is shorted (e.g. used with switch), the board will overheat and shut down.

Nominal trip level is with the Load Pot set to (60 %). A temperature sensor will trip with hot water at around 40

º

C

and a current one around 1.5 A. Time Pot setting is from 1 to 25 minutes with a default of 20 minutes.

A one-second push on a momentary switch wired to SW4 will run boost for up to 25 minutes. The overrun timer
can be set from 15 to 30 mins. A second one-second push will cancel the boost as would a “cancel boost”
signal from one of the sensors. Multiple momentary switches may be wired in parallel to SW4.

Screens for each of the three switches are displayed.
Enter a percentage value for the Load Pot setting.
