Application

The Danfoss Randall FP975 7-day full programmer
and TS975 7-day time switch offer all the control
flexibility and user features of their counterparts in the
regular Mk18 range (FP75 and TS75), but with two
important differences.
1) These units are intended specifically to replace, or
upgrade systems with, Danfoss Randall Mk.9 time
controls. They have British Gas Standard wallplates
used by many other models, including the Danfoss
Randall SET range, the Horstmann 425 Diadem and
Tiara, and their 525 and 527 models.
2) Both models have voltage-free output contacts,
making them applicable to systems with low voltage
control circuits, e.g. combination boilers or warm air.
Units are supplied with SET wallplates but, simply by
re-positioning a small switch in the back, interchangeability
is achieved with Mk.9 controls.
Replace models With
922 & 972 FP975
911 & 971 TS975
Both the FP975 and the TS975 are supplied as full 7-
day controls, but the installer can easily and quickly
convert them to weekday/weekend units if preferred.
