Not use to this dual temp. setup. Use to seeing Sporlan SORIT with solenoid in the pilot line! Switched the toggle switch at bottom of case and the DT coil does not appear to energize or deenergize and top coil is enrgized but will only stay in med. temp. need low temp. ? Have an old Danfoss NC25-- DT setup is com on? Switched to manual on still med. temp!
