Honeywell ST699 User manual

HEATING CONTROLS
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.
