Classic controlsClassic time controls are recommended only for use as like-for-like replacements. They come in either a

1-day programmer version (ST699) or a 7-day programmer version (ST799).

Single channel timeswitch controlsST9100 single channel timeswitches are designed for control of a single heating zone or combi boiler

applications. The three timeswitches in the range are:

• ST9100A – 1-day timeswitch

• ST9100C – 7-day timeswitch to suit 7-day, and 5/2 day, timing profiles

• ST9100S – 1-day timeswitch with a service interval reminder.

Two channel programmersST9400 programmers are two channel programmers with independent timing for control of heating and

hot water. The three programmers in the range are:

• S9400A – 1-day programmer with two channels

• ST9400C – 7-day programmer, two channels to suit 7-day or 5/2-day timing profiles

• ST9400S – 1-day programmer, two channel model with a service interval reminder.

Two zone programmersST9500C is a two channel 7-day full programmer designed to control two heating zones. Zoning a house

not only helps make the heating system more energy efficient, but can also improve comfort conditions,

as each zone will only be heated when required. Building regulations strongly recommend zoning for

most houses and mandate it for certain larger properties.

Wireless enabled packsSundial RF2 packs are boxed sets of controls that feature a combination of a wireless enabled timer,

wireless thermostat and wireless cylinder thermostat to suit a range of installation types.

ST6991 Day Classic Programmer

The ST699 time control programmer can be used as a

replacement programmer on gravity, primary or fully

pumped systems.

The ST699 has a proven, easy-to-use design. The front

panels of each programmer will fit to the same back plate.

Programming the timing sequence is straightforward,

using the top slider switch and [+] and [−] buttons.

Please note it is recommended that, in order to comply with Part L1 Building Regulations, central heating systems should be upgraded to fully pumped with a fully independent programmer, e.g. ST9400C.

InstallationThe ST699 programmer can be either surface or flush

mounted, for both of which fixing screws are supplied. The

wiring sub-base has holes to suit single pattress boxes

and breakouts for surface and channelled wiring.

If used to provide time control for a gravity hot water /

pumped heating system, it is not possible to select

Heating only without Hot Water. For these installations a

Heating and Hot Water sticker is supplied, which should

be placed over the existing HEATING caption.

Fixing screws are supplied for either surface or flush

mounting box.
