The FP975 is supplied fi tted with a Danfoss Randall SET wallplate.
However the FP975 will also mount directly onto a Danfoss Randall

when used with existing MK.9 wallplates the left hand switch
must be set in the MK.9 position to re-confi gure the time control
to match MK.9 wiring connections.

controlled is a) fully pumped with a mid-position valve, b) fully
pumped with a two port zone valve in each circuit, c) GRAVITY
