FP975

Electronic 7-Day Programmer

Application

The FP975 7-day full programmer oﬀ ers all

the control ﬂ exibility and user features of its

counterpart, FP715, in the regular Mk18 range,

but with two important diﬀ erences:

1) This unit is intended speciﬁ cally to replace, or

upgrade systems with, Danfoss Randall Mk.9

time controls. They have British Gas Standard

wallplates which are used by many other

models, including the Danfoss Randall SET

range, the Horstmann 425 Diadem and Tiara,

and their 525 and 527 models.

2) This model has voltage-free output contacts,

making it applicable to systems with low

voltage control circuits, e.g. combination

boilers or warm air.

The unit is supplied with a SET wallplate but,

simply by re-positioning a small switch on the

back, interchangeability is achieved with Mk.9

controls.

Replace models With

922 & 972 FP975

The FP975 is supplied as a full 7-day control, but

the installer can easily and quickly convert it to a

weekday/weekend or 24 hour unit if preferred.

The FP975 will plug on to the wallplates of

both Danfoss Randall Mk.9 and SET time

controls.

When used on an existing correctly wired

MK.9 wallplate, no wiring changes need to

be made but the small switch on the back

of the new unit should be re-positioned as

shown overleaf.

For SET replacement, no such adjustment

is necessary.
