APPLICATION
The ST699 and ST799 are time control programmers that can
be used as replacement programmers on gravity primary or fully
pumped systems. The ST699 has a proven easy to use design
that originates from 1980. The ST799 (shown) was introduced to
offer a flexible 7 day programme.
The front panels of each programmer will fit to the same
backplate. 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.
