Supply temperature control with 0 to 10Vdc SCR and override input

By closing contact on BI 1, will force setpoint to

« Unocc HT » adjustable inside setup parameters.

By adjusting to a low setpoint (ex: 0°F) is a way to

disable heating. By adjusting to 180°F, is a way to

force maximum heating.

If parameter « MenuScro » = On, will display

« Unoccup » when contact closed and

« Occupied » when contact open.
