You can now select or deselect the zones by pushing the green zone selection buttons, numbered 22 to 31 inclusive (See "Controls Layout" under the General heading).

The zone will be selected to run when the button becomes illuminated. If one of the buttons refuses to illuminate select that zone by pushing the grey up down buttons on the panelview itself. When the zone becomes highlighted in the box, check to see if the label to the right of the selected zone changes between "Off" and "On" when the green zone button is pushed. If this label changes then you have a blown or faulty lamp in the zone selection button. If the label does not change, please contact your current service provider, as you will not be able to select that zone for instant heat.
